主要统计指标解释

能源生产总量  指一定时期内，一个国家或地区一次能源生产量的总和。该指标是观察全省能源生产水平、规模、构成和发展速度的总量指标。一次能源生产量包括原煤、原油、天然气、水电、核能及其他动力能(如风能、地热能等)发电量，不包括低热值燃料生产量、生物质能、太阳能等的利用和由一次能源加工转换而成的二次能源产量。

能源消费总量  指一定时期内，一个国家或地区各行业和居民生活消费的各种能源的总和。该指标是观察能源消费水平、构成和增长速度的总量指标。能源消费总量包括原煤和原油及其制品、天然气、电力，不包括低热值燃料、生物质能和太阳能等的利用。能源消费总量分为终端能源消费量、能源加工转换损失量和能源损失量三部分。

(1)终端能源消费量：指一定时期内，一个国家或地区生产和生活消费的各种能源在扣除了用于加工转换二次能源消费量和损失量以后的数量。

(2)能源加工转换损失量：指一定时期内，一个国家或地区投入加工转换的各种能源数量之和与产出各种能源产品之和的差额。该指标是观察能源在加工转换过程中损失量变化的指标。

(3)能源损失量：指一定时期内，能源在输送、分配、储存过程中发生的损失和由客观原因造成的各种损失量，不包括各种气体能源放空、放散量。

能源生产弹性系数  是研究能源生产增长速度与国民经济增长速度之间关系的指标。计算公式：

国民经济年平均增长速度，可根据不同的目的或需要，用国民生产总值、国内生产总值等指标来计算，本年鉴是采用国内生产总值指标计算的。

电力生产弹性系数  是研究电力生产增长速度与国民经济增长速度之间关系的指标。一般来说，电力的发展应当快于国民经济的发展，也就是说电力应超前发展。计算公式为：

能源消费弹性系数  反映能源消费增长速度与国民经济增长速度之间比例关系的指标。计算公式为：

电力消费弹性系数  反映电力消费增长速度与国民经济增长速度之间比例关系的指标。计算公式为：

能源加工转换效率  指一定时期内，能源经过加工、转换后，产出的各种能源产品的数量与同期内投入加工转换的各种能源数量的比率。该指标是观察能源加工转换装置和生产工艺先进与落后、管理水平高低等的重要指标。计算公式为：

单位国内生产总值能耗  指一定时期内，一个国家或地区每生产一个单位的国内生产总值所消耗的能源。计算公式为：

单位国内生产总值电耗  指一定时期内，一个国家或地区每生产一个单位的国内生产总值所消耗的电力。计算公式为：

单位工业增加值能耗  指一定时期内，一个国家或地区每生产一个单位的工业增加值所消耗的能源。计算公式为：

Explanatory Notes on Main Statistical Indicators

Total Energy Production  refers to the total production of primary energy by all energy producing enterprises in the province in a given period of time. It is

a comprehensive indicator to show the level, scale, composition and pace of development of energy production of the country. The production of primary energy includes that of coal, crude oil, natural gas, hydro-power and electricity generated by nuclear energy and other means such as wind power and geothermal power. However, it does not include the production of fuels of low calorific value, bio-energy, solar energy and secondary energy converted from primary energy.

Total Energy Consumption refers to the total consumption of energy of various kinds by the production sectors and the households in the province in a given period of time. It is a comprehensive indicator to show the scale, composition and pace of increase of energy consumption. Total energy consumption includes that of coal, crude oil and their products, natural gas and electricity. However, it does not include the consumption of fuel of low calorific value, bio-energy and solar energy. Total energy consumption can be divided into three parts: end-use energy consumption; loss during the process of energy conversion; and energy loss.

(1)End-use Energy Consumption: It refers to the total energy consumption by the production sectors and the households in the province (region) in a given period of time. It does not include the consumption during the conversion of primary energy into secondary energy and the loss in the process of energy conversion.

(2)Loss During the Process of Energy Conversion: It refers to the total input of various kinds of energy for conversion, minus the total output of various kinds of energy in the province in a given period of time. It is an indicator to show the loss that occurs during the process of energy conversion.

(3)Energy Loss: It refers to the total of the loss of energy during the course of energy transport, distribution and storage and the loss caused by any objective reason in a given period of time. The loss of various kinds of gas due to gas discharges and stocktaking is not included.

Elasticity Ratio of Energy Production  is an indicator to show the relationship between the growth rate of energy production and the growth rate of the national economy. The formula is:

The average annual growth rate of the national economy can be measured by indicators such as the Gross National Product and the Gross Domestic Product, depending on the purposes or needs. The Gross Domestic Product has been used in the calculation of the ratio in this Yearbook.

Elasticity Ratio of Electricity Production  is an indicator to show the relationship between the growth rate of electricity production and the growth rate of the national economy. Generally speaking, the growth rate of electricity production should be higher than that of the national economy.

Its formula is:

Elasticity Ratio of Energy Consumption is an indicator to show the relationship between the growth rate of energy consumption and the growth rate of the national economy. The formula is:

Elasticity Ratio of Electricity Consumption is an indicator to show the relationship between the growth rate of electricity consumption and the growth rate of the national economy. The formula is:

Efficiency of Energy Processing and Conversion  refers to the ratio of the total output of energy products of various kinds after processing and conversion to the total input of energy of various kinds for processing and conversion in the same reference period. It is an important indicator to show the current conditions of energy processing and conversion equipment, production technique and management. The formula is:

Energy Consumption per Unit of GDP  refers to the energy consumption per unit of Gross Domestic Product in a province or the Gross Regional Product in a region in the same reference period. The formula is:
