【地区生产总值(地区GDP)】指按市场价格计算的一个地区所有常住单位在一定时期内生产活动的最终成果。地区生产总值有三种表现形态，即价值形态、收入形态和产品形态。从价值形态看，它是所有常住单位在一定时期内生产的全部货物和服务价值与同期投入的全部非固定资产货物和服务价值的差额，即所有常住单位的增加值之和；从收入形态看，它是所有常住单位在一定时期内形成的劳动者报酬、生产税净额、固定资产折旧、营业盈余等各项收入之和；从产品形态看，它是所有常住单位在一定时期内最终使用的货物和服务价值与货物和服务净流出价值之和。

【三次产业】三次产业的划分是世界上较为常用的产业结构分类，但各国的划分不尽一致。根据《国民经济行业分类》（GB/T 4754—2017）和《三次产业划分规定》，我国的三次产业划分是：

第一产业是指农、林、牧、渔业（不含农、林、牧、渔专业及辅助性活动）。

第二产业是指采矿业（不含开采专业及辅助性活动），制造业（不含金属制品、机械和设备修理业），电力、热力、燃气及水生产和供应业，建筑业。

【生产税净额】指生产税减生产补贴后的余额。生产税指政府对生产单位从事生产、销售和经营活动以及因从事生产活动使用某些生产要素(如固定资产和土地等)所征收的各种税收、附加费和规费。生产补贴与生产税相反，指政府为影响生产单位生产、销售及定价等生产活动而对其提供的无偿支出，因此视为负生产税，包括农业生产补贴、政策亏损补贴等。

【固定资产折旧】指由于自然退化、正常淘汰或损耗而导致的固定资产价值下降，用以代表固定资产通过生产过程被转移到其产出中的价值。

【营业盈余】指常住单位创造的增加值扣除劳动者报酬、生产税净额和固定资产折旧后的余额。

【支出法国内生产总值】是从最终使用的角度反映一个国家(或地区)一定时期内生产活动最终成果的一种方法，包括最终消费支出、资本形成总额及货物和服务净出口三部分。计算公式为：

支出法国内生产总值=最终消费支出+资本形成总额+货物和服务净出口

【最终消费支出】最终消费支出指常住单位为了直接满足个人或公共消费需求而对货物和服务的支出总额。最终消费支出分为居民消费支出和政府消费支出。

【居民消费支出】指常住居民为了直接满足生活需要购买和使用货物及服务的消费支出。居民消费支出既包括直接以货币形式购买货物和服务，也包括通过实物报酬形式得到的货物和服务以及居民自产自用的货物，还包括虚拟计算的自有住房服务和间接计算的金融中介服务。

【政府消费支出】指政府部门为全社会提供公共服务发生的消费支出，和免费或以没有显著经济意义价格向居民提供货物和服务的净支出。

【资本形成总额】反映常住单位在核算期非金融生产资产的积累情况，包括固定资本形成总额和存货变动两部分。

【固定资本形成总额】指生产者获得减处置的固定资产的价值，加上附着于非生产资产价值上的某些特定支出，如所有权转移费用。固定资产是通过生产活动生产出来的，在生产活动中使用一年以上，单位价值在规定标准以上的资产，不包括自然资产、耐用消费品、小型工器具。固定资本形成总额按购买者价格计算，并在所有权发生变化时记录。目前的核算内容主要包括住宅，其他建筑和构筑物，机器和设备，知识产权产品的获得减处置等。

【存货变动】指常住单位存货实物量变动的市场价值，即期末价值减期初价值的差额，其中不包括核算期内由于价格变动而产生的持有损益。存货的核算范围既包括生产单位购进的原材料、燃料和储备物资等存货，也包括生产单位生产的产成品、在制品和半成品等存货。存货变动可以是正值，也可以是负值，正值表示存货增加，负值表示存货减少。根据资料来源，存货变动按行业计算。

【可比价格】指在不同时期的价值指标对比时，扣除了价格变动的因素，以确切反映物量的变化。按可比价格计算有两种方法：一种是直接用产品产量乘某一年的不变价格计算；另一种是用价格指数换算。

【平均增长速度】表明社会经济现象在一个较长的时期内逐期平均增长变化的程度，它不能根据各个环比增长速度直接求得，但与平均发展速度之间存在着一定的数量关系：平均增长速度＝平均发展速度－1。平均发展速度是一种根据环比发展速度计算的序时平均数，由于各时期对比的基础不同，所以计算平均发展速度不能采用一般的序时平均数的计算方法，计算方法分为水平法和累计法。水平法，又称几何平均法，即将环比发展速度按连乘法用几何平均数公式计算。累计法，也称方程法，根据一段时期内各年发展水平总和与基期水平的关系，列出方程式计算平均发展速度。水平法着重考虑最后一年所达到的发展水平；累计法着重考虑整个时期累计发展水平的总量。

本年鉴内所列的平均增长速度，除固定资产投资用“累计法”计算外，其余均用“水平法”计算。从某年到某年平均增长速度的年份，均不包括基期年在内。如1979 年平均增长速度是以1978年为基期计算的，余类推。

【Gross Domestic Product (GDP)】refers to the final results of production activities of all resident units in a region in a certain period of time calculated at market prices. 3. There are three forms of gross regional product, namely value form, income form and product form. From the perspective of value pattern, it is the difference between the value of all goods and services produced by all resident units in a certain period and the value of all goods and services of non-fixed assets invested in the same period, that is, the sum of the added value of all resident units.

In terms of product form, it is the sum of the value of goods and services ultimately used by all resident units and the net outflow value of goods and services within a certain period.

【Three Strata of Industry】The division of the three industries is the commonly used industrial structure classification in the world, but the division of different countries is not consistent. According to the "Classification of National Economic Industries" (GB/T 4754 -- 2017) and "Regulations on the Division of Tertiary Industries", China's tertiary industries are divided as follows:

The primary industry refers to agriculture, forestry, animal husbandry and fishery (excluding agriculture, forestry, animal husbandry and fishery specialties and auxiliary activities).

The secondary industry refers to mining (excluding mining specialty and auxiliary activities), manufacturing (excluding metal products, machinery and equipment repair), production and supply of electricity, heat, gas and water, and construction.

The tertiary industry, that is, the service industry, refers to the industries other than the primary and secondary industries.

【Compensation of Employees】refers to the total remuneration obtained by a laborer for engaging in productive activities. It includes remuneration in monetary form as well as remuneration in kind form. It mainly includes salary, bonus, allowance and subsidy, social insurance premium paid by the unit for its employees, supplementary social insurance premium and housing accumulation fund, pension for the employees of administrative institutions, employee stock options and other forms of remuneration and welfare provided by the unit for its employees.

【Net Taxes on Production】refers to the balance of production tax less production subsidy. Production tax refers to all kinds of taxes, surcharges and fees levied by the government on production units engaged in production, sales and business operations and on the use of certain factors of production (such as fixed assets and land, etc.) for production activities. In contrast to production tax, production subsidy refers to the government's free expenditure to production units in order to affect production, sales and pricing of production activities, so it is regarded as negative production tax, including agricultural production subsidies, policy loss subsidies, etc.

【Depreciation of Fixed Assets】A decline in the value of a fixed asset due to natural degradation, normal obsolescence or depletion, used to represent the value of a fixed asset transferred to its output through the production process.

【Operating Surplus】refers to the balance of the value added created by the resident units after deducting the labourers remuneration, net taxes on production and the depreciation of fixed assets.

【GDP by Expenditure Approach】refers to the method of measuring the final results of production activities of a country (region) during a given period from the perspective of final uses. It includes final consumption expenditure, gross capital formation and net export of goods and services. The formula for computation is:

GDP by expenditure approach = final consumption expenditure + gross capital formation + net export of goods and services.

【Final Consumption Expenditure】refers to the total expenditure of a resident unit on goods and services to directly meet personal or public consumption needs. Final consumption expenditure is divided into household consumption expenditure and government consumption expenditure.

【Household Consumption Expenditure】refers to the consumption expenditure of permanent residents to purchase and use goods and services directly to meet their daily needs. Residents' consumption expenditure includes not only goods and services purchased directly in the form of money, goods and services obtained in the form of physical remuneration and goods produced and used by residents themselves, but also self-owned housing services calculated virtually and financial intermediary services calculated indirectly.

【Government Consumption Expenditure】refers to the consumption expenditure incurred by government departments in providing public services to the whole society, and the net expenditure on providing goods and services to residents free of charge or at a price of no significant economic significance.

【Gross Capital Formation】reflects the accumulation of non-financial productive assets of the resident unit during the accounting period, including gross fixed capital formation and inventory changes.

【Gross Fixed Capital Formation】refers to the value of the fixed assets acquired by the producer less disposed of, plus certain expenses attached to the value of the non-productive assets, such as ownership transfer expenses. Fixed assets are assets produced through production activities, used in production activities for more than one year, and whose unit value is above the prescribed standard, excluding natural assets, consumer durables and small industrial appliances. Gross fixed capital formation is calculated at purchasers' prices and recorded when there is a change in ownership. The current accounting mainly includes residential buildings, other buildings and structures, machinery and equipment, acquisition minus disposal of intellectual property products, etc.

【Changes in Inventories】refers to the market value of the change in the physical inventory of resident units, namely, the difference between the ending value and the beginning value, excluding the holding gains and losses arising from the price change during the accounting period. The accounting scope of inventory includes not only the inventories of raw materials, fuels and reserve materials purchased by the production units, but also the inventories of finished products, work-in-process and semi-finished products produced by the production units. Inventory changes can be positive or negative, with a positive value indicating an increase in inventory and a negative value indicating a decrease. Inventory changes are calculated by industry, depending on the source.

【Comparable price】refers to when the value index is compared in different periods, the factors of price change are deducted to reflect the change of material quantity. There are two methods to calculate the comparable price: one is to calculate the product output directly by the constant price of a certain year, and the other is to convert by the price index.

【Average Annual Growth Rate】shows the average growth rate of social and economic development during a longer period. It can not be directly calculated by chain based growth rate. The relation is:

Average Annual Growth Rate = Average Speed of Development - 1

Average speed of development is the time series average of speed which calculated by chain based. Because the reference bases during the different periods are not same, average speed of development can not be calculated by the general method. Level approach and accumulative approach for calculating average speed of development rate are applied. The "level approach", or the method of calculating the geometric average, is derived by the formula of geometric average of the chain-based speeds of development, or comparing the level of the last year of the interval with that of the beginning year; the other is called the "accumulative approach" or the "algebraic average", "equation" method, which is derived by the summation of the actual figure of each year in the interval divided by the figure in the base year. The level approach focuses on the level of the last year, while the accumulative approach emphasizes the aggregate development in the duration.

The average annual growth rates listed in the yearbook are calculated by the level approach except for the growth rate of investment in fixed assets. The base year is not listed in the duration for which average annual growth rates are computed. For example, the average growth rate in 1979 is calculated on the basis of 1978, and so on.
