主要统计指标解释

全社会固定资产投资  是以货币形式表现的在一定时期内全社会建造和购置固定资产的工作量以及与此有关的费用的总称。该指标是反映固定资产投资规模、结构和发展速度的综合性指标,又是观察工程进度和考核投资效果的重要依据。全社会固定资产投资按登记注册类型可分为国有、集体、个体、联营、股份制、外商、港澳台商、其他等。

城镇固定资产投资　指城镇各种登记注册类型的企业、事业、行政单位及个体户进行的计划总投资(或实际需要总投资)50万元及50万元以上的建设项目投资和房地产开发投资。县城及以上区域内发生的投资，县及县以上各级政府及主管部门直接领导、管理的建设项目和企业事业单位的投资均为城镇固定资产投资。

房地产开发投资  指各种登记注册类型的房地产开发公司、商品房建设公司及其他房地产开发法人单位和附属于其他法人单位实际从事房地产开发或经营活动的单位统一开发的包括统代建、拆迁还建的住宅、厂房、仓库、饭店、宾馆、度假村、写字楼、办公楼等房屋建筑物和配套的服务设施，土地开发工程（如道路、给水、排水、供电、供热、通讯、平整场地等基础设施工程）的投资；不包括单纯的土地交易活动。

农村投资　包括在农村区域范围内进行固定资产投资活动的企业、事业、行政单位及农户投资。

建设总规模　是指在报告期内所有施工项目的计划总投资。这个指标和施工项目相对应。

在建总规模　是指在报告期末所有在建项目的计划总投资。

在建净规模　是指报告期末所有在建项目建成投产尚需的投资总量。

在建净规模＝在建总规模－未投产项目（期末在建）累计完成投资。

固定资产投资的资金来源  根据固定资产投资的资金来源不同，分为国家预算内资金、国内贷款、利用外资、自筹资金和其他资金。

(1)国家预算内资金：分为财政拨款和财政安排的贷款两部分。包括中央财政的基本建设基金(分经营性基金和非经营性基金两部分)、专项支出(如煤代油专项等)、收回再贷、贴息资金，财政安排的挖潜改造和新产品试制支出、城建支出、商业部门简易建筑支出、不发达地区发展基金等资金中用于固定资产投资的资金；地方财政中由国家统筹安排的资金等。

(2)国内贷款：指报告期固定资产投资单位向银行及非银行金融机构借入的用于固定资产投资的各种国内借款，包括银行利用自有资金及吸收的存款发放的贷款、上级主管部门拨入的国内贷款、国家专项贷款、地方财政专项资金安排的贷款、国内储备贷款、周转贷款等。

(3)利用外资：指报告期收到的用于固定资产建造和购置的国外资金(包括设备、材料、技术在内)。包括对外借款(外国政府、国际金融组织贷款、出口信贷、外国银行商业贷款、对外发行债券和股票)、外商直接投资及外商其他投资。不包括我国自有外汇资金(国家外汇、地方外汇、留成外汇、调剂外汇和中国银行自有资金发行的外汇贷款等)。计算利用外资时，需要折算成人民币，折算中所使用的外汇汇率按现汇计算，即按使用外汇时的汇率计算。

(4)自筹资金：指固定资产投资单位报告期收到的，由各地区、各部门及企、事业单位筹集用于固定资产投资的预算外资金，包括中央各部门、各级地方和企、事业单位的自筹资金。

(5)其他资金：指在报告期收到的除以上各种资金之外其他用于固定资产投资的资金，包括企业或金融机构通过发行各种债券筹集到的资金、群众集资、个人资金、无偿捐赠的资金及其他单位拨入的资金等。

固定资产投资按国民经济行业分  根据建设项目建成投产后的主要产品或主要用途及社会经济活动性质来确定国民经济行业。一般情况下，一个建设项目或一个企业、事业单位只能属于一种国民经济行业。

固定资产投资按隶属关系分  是按建设单位或企业、事业、行政单位的主管上级机关确定的。

（1）中央：是指中共中央、人大常委会和国务院各部、委、局、总公司以及直属机构直接领导的建设项目和企业、事业、行政单位。这些单位的固定资产投资计划由国务院各部门直接编制和下达，建设中所需物资、主要设备以及建设中的问题都由中央有关部门安排和解决。

（2）地方：是由省（自治区、直辖市）、地区（州、盟、省辖市）、县（旗、县级市）三级政府及业务主管部门直接领导和管理的建设项目、企业、事业、行政单位。地方项目还包括不隶属以上各级政府及主管部门的建设项目和企业、事业单位，如外商投资企业和无主管部门的企业等。

固定资产投资按建设性质分  根据整个建设项目情况来确定。建设项目的性质一般分为新建、扩建、改建和技术改造、迁建、恢复。房地产开发单位、农村投资、城镇工矿区私人建房投资不划分建设性质。

(1)新建：一般指从无到有开始建设的企业、事业和行政单位或建设项目。现有企业、事业、行政单位一般不属于新建。但如有的单位原有基础很小，经过建设后新增的固定资产价值超过该企、事业、行政单位原有固定资产价值(原值)三倍以上的也应作为新建。

(2)扩建：指在厂内或其他地点，为扩大原有产品的生产能力(或效益)或增加新的产品生产能力，而增建主要的生产车间(或主要工程)、分厂、独立的生产线。行政、事业单位在原单位增建业务用房(如学校增建教学用房、医院增建门诊部、病房等)也作为扩建。

现有企、事业单位为扩大原有主要产品生产能力或增加新的产品生产能力，增建一个或几个主要生产车间(或主要工程)、分厂，同时进行一些更新改造工程的，也应作为扩建。

(3)改建和技术改造：指现有企业、事业单位，对原有设施进行技术改造或更新(包括相应配套的辅助性生产、生活福利设施) 的建设项目。现有企业、事业单位为适应市场变化的需要，而改变企业的主要产品种类(如军工企业转产民用品等) 的建设项目，应作为改建。原有产品生产作业线由于各工序(车间)之间能力不平衡，为填平补齐充分发挥原有生产能力而增建不增加本企业主要产品设计能力的车间，也应作为改建。技术改造是指企业、事业单位在现有基础上，用先进的技术代替落后的技术，用先进的工艺和装备代替落后的工艺和装备，以改变企业落后的技术经济面貌，实现以内涵为主的扩大再生产，达到提高产品质量、促进产品更新换代、节约能源、降低消耗、扩大生产规模、全面提高社会经济效益的目的。技术改造具体包括以下内容：机器设备和工具的更新改造；生产工艺改革、节约能源和原材料的改造；厂房建筑和公共设施的改造；劳动条件和生产环境的改造等。

(3)其他费用：指在固定资产建造和购置过程中发生的，除上述几项内容以外的各种应分摊计入固定资产的费用。

施工项目  指报告期内进行过建筑或安装施工活动的项目。凡是报告期内施过工的建设项目，不论施工时间长短，均作为施工项目统计。施工项目个数可以反映一定时期固定资产投资的实际规模，与同期全部建成投产项目个数相比，可以从建设速度的角度反映固定资产投资的效果。根据建设项目施工活动的不同性质，施工项目又分为：本年正式施工项目、本年收尾项目和以前年度全部停缓建项目。

全部建成投产项目  工业项目指设计文件规定形成生产能力的主体工程及其相应配套的辅助设施全部建成，经负荷试运转，证明具备生产设计规定合格产品的条件，并经过验收鉴定合格或达到竣工验收标准，与生产性工程配套的生活福利设施可以满足近期正常生产的需要，正式移交生产的建设项目。非工业项目指设计文件规定的主体工程和相应的配套工程全部建成，能够发挥设计规定的全部效益，经验收鉴定合格或达到竣工验收标准，正式移交使用的建设项目。

新增生产能力(或工程效益)  指通过固定资产投资活动而增加的设计能力(或工程效益)，该指标是以实物形态表现的反映固定资产投资成果的指标，也是考核投资经济效果的重要依据之一。

新增生产能力(或工程效益)一般有以下几种表现形式：

(1)用产品数量表示，以工程在单位时间内(一般是一年)所能生产的产品数量(即年产量)表示。如原煤开采用万吨／年表示，化学农药用吨／年表示，拖拉机制造用台／年表示等。某些化工产品由于含量差别较大，按其设计含量计算折合量表示，如硫酸、纯碱、烧碱等。

(2)用单位时间内所能处理的原料数量表示，以工程每天(或小时)所能处理原料的数量表示。如机制糖工程日处理原料吨，食用植物油日处理原料吨，城市污水处理能力用万吨／日表示等。

(3)用新增加的主要设备的数量或容量表示，如新增棉布织机、丝织机等台数，毛纺锭等锭数，发电厂新增发电机组容量用千瓦表示等。

(4)用建筑物容积、容量、面积、长度表示，是非工业项目或工程新增效益的一种表现形式。如铁路投产里程、新建公路、水库容量、粮食仓库、学校学生席位、医院病床、有效灌溉面积等。

根据工程的特点，有时需要用两种或两种以上的复合计量单位表示新增生产能力(或工程效益)，如新增内燃机生产能力同时用年产台数、千瓦数表示等。

为了规范新增生产能力(或工程效益)的名称和计算单位，国家统计局制订了《新增生产能力(或工程效益)目录及代码》。各固定资产投资单位在统计新增生产能力(或工程效益)时，必须按目录中规定的名称、计量单位和代码填报。

房屋建筑面积  指房屋建筑物勒脚以上外墙外围的水平截面面积，包括房屋建筑物的有效面积和结构面积。该指标是从实物形态上反映建设规模和建设成果的重要指标之一，也是检查工程形象进度、计算工程造价、分析投资效果、研究施工任务和建筑材料之间平衡情况的重要依据。

住宅建筑面积  指施工和竣工房屋建筑面积中供居住用的房屋建筑面积。

施工面积  指报告期内施工的全部房屋建筑面积。包括本期新开工的面积和上期开工跨入本期继续施工的房屋面积，以及上期已停建在本期恢复施工的房屋面积。本期竣工和本期施工后又停缓建的房屋，其建筑面积仍计入本期房屋施工面积中。

竣工面积  指在报告期内房屋建筑按照设计要求已经全部完工，达到住人和使用条件，经验收鉴定合格(或达到竣工验收标准)，正式移交使用单位的各栋房屋建筑面积的总和。

房屋建筑面积竣工率  指一定时期内房屋竣工面积占同期房屋施工面积的比率。

新增固定资产  指报告期内已经完成建造和购置过程，并已交付生产或使用单位的固定资产价值。该指标是表示固定资产投资成果的价值指标，也是反映建设进度，计算固定资产投资效果的重要指标。

项目建成投产率  指一定时期内全部建成投产项目个数与同期施工项目个数的比率。该指标是从建设单位建设速度的角度反映投资效果的指标。

固定资产交付使用率  指一定时期新增固定资产与同期完成投资额的比率。该指标是反映固定资产动用速度，衡量建设过程中宏观投资效果的综合指标。由于新增固定资产是较长时期内形成的结果，而投资额则是当年完成的，因此，该指标一般适宜于反映较长时期内固定资产的动用情况。

商品房销售面积  指报告期内出售商品房屋的合同总面积(即双方签署的正式买卖合同中所确定的建筑面积)。由现房销售建筑面积和期房销售建筑面积两部分组成。

商品房销售额  指报告期内出售商品房屋的合同总价款(即双方签署的正式买卖合同中所确定的合同总价)。该指标与商品房销售面积同口径，由现房销售额和期房销售额两部分组成。

经济适用房  指根据经济适用房计划安排建设的政策性住宅。经济是指房屋建筑造价和销售价格低于一般商品住宅；适用是指适合中低收入家庭购买使用。经济适用房主要是由国家统一下达投资计划，房地产公司开发，对外销售；用地一般采用行政划拨或招标投标方式，免收土地出让金；对各种经批准的收费减半征收，开发利润不超过3%；销售价格实行政府指导价。该指标可以分析房地产投资结构，反映中低收入家庭商品住宅的供求平衡情况。

Explanatory Notes on Main Statistical Indicators

Total Investment in Fixed Assets in the Whole Country   refers to the volume of activities in construction and purchases of fixed assets of the whole country and related fees, expressed in monetary terms during the reference period. It is a comprehensive indicator which shows the size, structure and growth of the investment in fixed assets, providing a basis for observing the progress of construction projects and evaluating results of investment. Total investment in fixed assets in the whole country includes, by type of ownership, the investment by State-owned units, collective-owned units, individuals, joint ownership units, share-holding units, as well as investments by entrepreneurs from foreign countries and from Hong Kong, Macao and Taiwan, and by other units.

Urban Investment in Fixed Assets  refers to construction projects involving a total planned (or required) investment of 500,000 yuan and over by enterprises of various types of ownership, institutions, administrative units and individuals in urban areas, investment in real estate development. In other words, all investments that take place in county towns and urban areas, investment in construction projects under the direct leadership and management of government agencies at and above county levels and investments by enterprises and institutions at and above county levels are covered in urban investment in fixed assets.

Investment in Real Estate Development   refers to investment by real estate development companies, commercialized buildings construction companies and other real estate development units of various types of ownership in the construction of buildings, such as residential buildings, factory buildings, warehouses, hotels, guesthouses, holiday villages, office buildings, and the complementary service facilities and land development projects, such as roads, water supply, water drainage, power supply, heating supply, telecommunications, land leveling and other infrastructural projects. It does not include activities in pure land transactions.

Investment in Rural Areas   refers to investment in fixed assets by enterprises, institutions, administrative units and households in rural areas.

Total Size of Construction   refers to the planned total investment for all construction projects during the reference period. This item should correspond with projects under work.

Total Size of Investment in Projects under Construction   refers to the planned total investment of all projects under construction at the end of the reference period.

Net Size of Investment in Projects under Construction   refers to the outstanding requirement of investment of all projects under construction at the end of the reference period.

Net size of investment in projects under construction= Total size of investment – Accumulated completed investment of projects under construction

Sources of Funds for Investment in Fixed Assets  are categorized as funds from the State budget, domestic loans, foreign investment, self-raised funds, and others, depending on the sources of investment.

(1) Fund from the State budget consists of budgetary appropriation and loans from the State budget. More specifically, it includes, from the budget of the central government, capital construction fund (operation fund and non-operational fund), special expenses (e.g. expenses on substituting petroleum with coal), loans from repayment, discount fund, expenses on innovation and trial production of new products, expenses on urban construction, expenses on temporary construction from business departments, development fund for less developed areas, as well as local budgetary fund transferred from the central budget.

(2) Domestic loans refer to loans of various forms borrowed by investing units from banks and non-bank financial institutions during the reference period for the purpose of investment in fixed assets, including loans issued by banks from their self-owned funds and deposit, loans appropriated by higher authorities, special loans by government, loans arranged by local government from special funds, domestic reserve loan, and working loan.

(3) Foreign investment refers to foreign funds received during the reference period for the construction and purchase of investment in fixed assets (covering equipment, materials and technology), including foreign borrowings (loans from foreign governments and international financial institutions, export credit, commercial loans from foreign banks, issue of bonds and stocks overseas), foreign direct investment and other foreign investments. Excluded from this category is capital in foreign exchanges owned by China (foreign exchanges owned by the central and local governments, foreign exchanges retained by enterprises, foreign exchanges by enterprises through the regulating mechanism, loans in foreign exchanges issued by the Bank of China with its own fund, etc.). In calculating the utilization of foreign capital, foreign currencies are converted into Chinese Renminbi applying the current exchange rate when the foreign capitals are actually used.

(4) Self-raised funds refer to extra-budgetary funds for investment in fixed assets received during the reference period by investing units from central government ministries, local governments, enterprises and institutions, including their self-raised funds.

(5) Others refer to funds for investment in fixed assets received from sources other than those listed above, including capital raised through issuing bonds by enterprises or financial institutions, funds raised from individuals and through donations, and funds transferred from other units.

Investment in Fixed Assets by Sector the classification of construction projects by sector is determined by the major products or the purpose of the projects when they are put into production or use, and by the nature of their social economic activities. In general, one project or one enterprise or institution can only be classified into one sector.

Investment in Fixed Assets by Jurisdiction of Management   refers to the classification of investment by the competent authorities under which investment is made by construction units, enterprises, institutions or administrative units.

(1) Central investment refers to the investment in projects or by enterprises, institutions or administrative units which are under the direct leadership and management of the State Council and of the national commissions, ministries, agencies and State-owned large corporations. Various ministries and departments of the State Council prepare and implement plans for investment in fixed assets by those departments, and arrange and ensure the supply of materials and key equipment required for the projects.

(2) Local investment refers to the investment in projects or by enterprises, institutions or administrative units which are under the direct leadership and management of departments under the provincial, prefecture and county governments. Also included are projects by foreign-invested enterprises and enterprises without competent managing authorities.

Investment in Fixed Assets by Type of Construction  construction projects in general can be classified, by the type of construction, into new construction, expansion, reconstruction and technical transformation, moving and restoration. However, investment by type of construction is not applied to investment by real-estate development units, investment in rural areas and private investment in housing construction in urban areas and in industrial and mining areas.

(1) New construction in general refers to construction projects, which start from scratch, of enterprises, institutions, administrative agencies. Construction in existing enterprises, institutions or agencies is generally not considered as new construction. In case the size of the existing unit is quite small, and the value of newly added fixed assets is more than three times of the original value, the expansion will be considered as new construction.

(2) Expansion refers to construction of new major production workshop, branch factory or independent production line within a factory or in other locations, for the purpose of increasing the production capacity (or improving efficiency) or adding new production capacity. Newly constructed accommodation for the operation of institutions and administrative organizations (such as newly constructed buildings for teaching in schools, buildings for clinics or wards in hospitals, etc.) are also classified as expansion.

Also included in expansion are investments by existing enterprises or institutions in building major production line(s) or branch factory(ies) along with some work on innovation, for the purpose of expanding the production capacity of original products or producing new products.

(3) Reconstruction and technical transformation refers to construction projects by existing enterprises or institutions in innovation or technical transformation of the old facilities (including auxiliary production equipment and welfare facilities). Also considered as reconstruction is the construction of new workshops by the existing enterprises or institutions to change the variety of products to meet the market demand (such as the production of civil products by defense industries), or to bring the designed production capacity into full play through a more balanced production process on production lines. Technical transformation refers to replacement of old technology or equipment by new technology or equipment, in order to expand the reproduction through improvement of technology contents in production, to improve product quality, to promote new products, to save energy, to reduce consumption, to expand the production scale and to improve overall social-economic efficiency. Contents of technical transformation include: updating of machinery, equipment and tools; reforming production process by using energy or materials saving technology; construction of factory workshops and transformation of public facilities; improvement of working conditions and environment, etc.

Investment in Fixed Assets by Structure  by their contents and the mode of implementation, investment activities are classified into 3 categories, i.e. construction and installation, purchase of equipment and instrument, and other expenses.

(1) Construction and installation (work volume of construction and installation) refers to the construction of houses and buildings and the installation of various kinds of equipment and instruments. They include construction of houses; equipment foundations, industrial kilns and stoves, and metal structure work; preparation works and temporary works for project construction, and clearing up works post project construction; pavement of railways and roads, drilling of mines and putting up of oil pipes; construction of water conservancy; construction of underground air-raid shelters and construction of other special projects; value of equipment for heating, sanitation, ventilation, lighting, gas, painting, etc. that are covered by the budget of housing projects; laying out of various pipelines (for steam, compressed air, petroleum, tap water and sewage) and wiring and cabling for electric power and for communications; installation of various machinery and equipment; testing operation for pre-testing the quality of installation projects, and land and other development work conducted by real estate developers for commercialized housing. The value of equipment installed is itself not included in the value of installation projects.

(2) Purchase of equipment and instruments refers to the total value of equipment, tools, and instruments purchased or self-produced which come up to the cut-off point for fixed assets by the construction units or investing enterprises or institutions. Equipment, tools and instruments purchased or self-produced for new workshops by newly established or expanded units are categorized as “purchase of equipment and instruments” no matter whether they come up to the cut-off point for fixed assets.

(3) Other expenses refer to expenses arising during the construction or purchase of fixed assets other than those mentioned above.

Projects under Construction  refer to projects with construction and installation activities undertaken in the reference period. All projects that have construction activities undertaken during the reference period are reported as projects under construction irrespective of the length of construction work. The number of projects under construction can reflect the actual size of investment in fixed assets during a given period, and when compared with the number of projects completed and put into use during the same period, it demonstrates the results of investment in fixed assets from the angle of the speed of the construction. Depending on the nature of construction activities, projects under construction can also be classified into projects beginning construction in current year, winding-up projects in current year and stopped or suspended projects in previous years (with resumption of work in current year).

Projects Completed and Put into Use  Industrial projects refer to the major projects and auxiliary facilities having been completed in accordance with the design documents, resulting in forming production capacity and having checked and accepted after relevant tests, while the living and welfare facilities having been completed and being capable of ensuring normal production. Non-industrial projects refer to the major projects and auxiliary facilities which have been completed in accordance with the design documents; have been checked, accepted after relevant examination; and have been formally delivered for use.

Newly Increased Production Capacity (or Project Efficiency) refers to the increase in design capacity (or project efficiency) through investment in fixed assets, which reflects the accomplishment of investment in fixed assets in physical form and serves as an important basis for evaluating the economic efficiency of investment.

The newly increased production capacity (project efficiency) is usually expressed in one of the following forms:

(1) Volume of output of products, i.e. the volume of output that the project can produce during a given period (usually a year). For instance, the capacity in coal mining is expressed in 10,000 tons/year, the capacity in producing chemical pesticides expressed in ton/year, the capacity in producing tractors in tractor/year, etc. For some chemical products where the effective contents differ significantly, the production capacity is expressed as the designed effective content equivalent, such as in the case of sulphuric acid, soda ash, caustic soda, etc;

(2) volume of raw materials processed per unit of time, i.e. the volume of raw materials that could be processed by the project per day (or per hour), such as tons of materials processed per day by a sugar refining project or edible vegetable oil project, or tons of urban sewage processed per day;

(3) number or capacity of major equipment increased, such as number of cotton or silk looms increased, wool spindles increased, or capacity (in kilowatts) of power generators increased; and

(4) physical measures (volume, capacity, area, and length) of construction, which is typical for non-industrial projects, for instance, the length of railways put into operation, the length of highways, the capacity of reservoirs, the capacity of warehouses, the floor space of housing projects, capacity for new students in schools or beds in hospitals, areas under new irrigation project, etc.

The special features of projects may sometimes call for the combined use of two or more measurements to reflect the increase in production capacity (or project efficiency); for instance, the new capacity for the production of internal combustion engines is expressed in sets per year and kilowatts per year simultaneously.

To standardize the nomenclature and unit of measurement for newly increased production capacity (or project efficiency), the National Bureau of Statistics has developed the Nomenclature and Codes for New Production Capacity (Project Efficiency). All reporting units with investment activities are required to follow these two nomenclatures in reporting statistics on new production capacity (project efficiency).

Floor Space of Buildings under Construction refers to the total floor space of the horizontal section of outer walls above the plinth of the building, including the effective area and the area occupied by the structure. This indicator is one of the important indicators in physical terms to reflect the scale and accomplishment of the construction industry and also an important basis for monitoring the progress, calculating the cost, analyzing the efficiency and studying the supply of building materials in relation to the construction projects.

Floor Space of Residential Buildings refers to the floor space of the residential buildings among the total space of buildings under construction or completed.

Floor Space under Construction   refers to total floor space of all buildings under construction during the reference period, including floor space of newly started buildings during the reference period, floor space of construction extended from the previous period to the current period, and floor space of construction suspended during the previous period and resumed in the current period. Floor space of construction completed in the current period, and floor space of construction started and then suspended in the current period are also included in the floor space under construction of the current year.

Floor Space Completed refers to the floor space of all buildings completed in the reference period, which have been appraised and accepted (or come up to the designed standards) and has been transferred to owner units.

Completion Rate of Floor Space of Buildings refers to the ratio of the floor space of buildings completed in a certain period of time to the floor space of buildings under construction in the same period.

Newly Increased Fixed Assets refer to the newly increased value of fixed assets, constructed or purchased, that have been transferred to the investors. This is an indicator that demonstrates the results of investment in fixed assets in monetary terms, and an important indicator to reflect the speed of construction and to calculate the efficiency of investment.

Rate of Construction Projects Completed and Put into Use refers to the ratio of the number of construction projects completed and put into use in a certain period of time to the number of projects under construction in the same period. This reflects the investment efficiency from the perspective of the speed of projects construction.

Rate of Projects of Fixed Assets Completed and Put into Operation refers to the ratio of the newly increased fixed assets to the total investment made in the same period. This is a comprehensive indicator reflecting the speed of the employment of fixed assets and the investment efficiency at the macro-level. As the newly increase fixed assets is the result of a long period while the investment is completed in the current year, this indicator is expected to be used to reflect the employment of fixed assets over a long period of time.

Area of Commercialized Housing Sold   refers to total contracted area of commercialized housing (i.e. area of floor space as designated in the formal contracts signed by both sides) during the reference time. It constitutes floor space of completed housing and floor space of future housing.

Value of Commercialized Housing Sold   refers to the total contracted value (i.e. value of sales/purchase for selling/purchase of commercialized housing as designated in the contract signed by both sides) during the reference time. This indicator has the same coverage as the area of commercialized housing sold, which constitutes floor space of completed housing and floor space of housing yet to be completed.

Economically Affordable Housing refers to housing constructed according to the State Plan for economically affordable housing. The features of houses of this category are low cost of construction and low prices, and therefore are affordable to mid-income and low income households. Economically affordable housing projects are developed by real estate companies under the State Investment Plan, with the land provided through government allocation or tendering procedures. Developers are exempted from land utilization fees and enjoy another 50% exemption of all other legitimate fees, while their profits are limited to less than 3%, and the completed houses are sold under government-guided prices. This indicator helps to analyze the investment structure of the real estate industry and the demand and supply of housing for mid-income and low income households.
