## 第一篇综　合

一、本篇资料反映广州国民经济和社会发展的综合情况以及国民经济核算情况，分别由广州市统计局综合统计处和国民经济核算处整理提供。

二、综合统计资料是根据广州市统计局各专业统计年报资料以及广州市有关部门提供的统计资料加工整理而成。

三、国民经济核算资料主要包括广州市地区生产总值及其有关资料。地区生产总值是根据不同产业部门、不同支出构成的特点和资料来源情况而采用不同方法计算的。2019年，根据第四次全国经济普查结果，我市对2008-2018年度地区生产总值数据进行了修订。

地区生产总值是一个价值量指标，其价值的变化受价格变化和物量变化两大因素影响。不变价地区生产总值是把按当期价格计算的地区生产总值换算成按某个固定期（基期）价格计算的价值，从而使两个不同时期的价值进行比较时，能够剔除价格变化的影响，以反映物量变化，反映生产活动成果的实际变动。地区生产总值指数就是根据两个时期不变价地区生产总值计算得到的。随着经济的不断发展，各行业的价格结构也会不断发生变化，为了更好的反映这种变化对于经济的影响，计算不变价地区生产总值需要每隔若干年调整一次基期。我国自开始核算国内生产总值以来，共有1952年、1957年、1970年、1980年、1990年、2000年、2005年、2010年、2015年9个不变价基期，目前的基期是2015年。2015-2017年的不变价地区生产总值是按照2015年价格计算的。

四、根据《国家统计局关于执行新国民经济行业分类国家标准的通知》（国统字〔2017〕142号）要求，新《国民经济行业分类》从2017年统计年报和2018年定期统计报表统一开始使用。本资料中凡是涉及到分行业的表式（除个别部门提供的数据仍按旧行业分类，表中有注明），均按照新的行业分类《国民经济行业分类GB/T4754-2017》作调整。

## 1　General Survey

I. The summary data in this chapter reflect the national economy and social development of Guangzhou and also cover the data on its national economic accounts. The data are prepared and provided by the Division of Comprehensive Statistics and the Division of National Accounts of Guangzhou Municipal Bureau of Statistics respectively.

II. The summary data are processed and prepared in the light of the annual reports of various specialized fields provided by Guangzhou Municipal Bureau of Statistics and data provided by some related departments of Guangzhou Municipality.

III.The data on the national economic accounts mainly cover the gross domestic Product (GDP)and related data of Guangzhou. The regional gross domestic product is calculated by different methods according to the characteristics and sources of different industrial sectors and different expenditure components. The GDP data of 2008-2018 are revised in 2019,according to the data of the fourth national economic census.

Regional GDP is an index of value, and the change of value is influenced by two factors: price change and material quantity change. The regional GDP at constant prices is converted to the value calculated at a fixed (base period) price at current prices, so that when comparing the values of two different periods, the effects of price changes can be excluded. In order to reflect the volume of change, reflect the actual changes in the results of production activities. Regional GDP index is based on two periods of constant price region GDP calculation. With the continuous development of economy, the price structure of various industries will change constantly. In order to better reflect the impact of this change on the economy, the base period should be adjusted once every several years to calculate the gross domestic product in the constant price area. Since the beginning of our gross domestic product (GDP) accounting, there have been nine constant price base periods in 1952, 1957, 1970, 1980, 1990, 2000, 2005, 2010 and 2015. The current base period is 2015. Gross domestic product in constant prices for 2015-2017 is calculated at 2015 prices.

IV. According to the notice of the National Bureau of Statistics on the implementation of the new national standard of national economic industry classification (2017) 142, the new national economic industry classification has been used from the statistical annual report of 2017 and the periodic statistical report of 2018.
