A gridded dataset comprising value-added of primary, secondary and tertiary industries in China under shared socioeconomic pathways from 2020-2100

The Cobb-Douglas production function is applied to project the output values of primary, secondary and tertiary industries in China at the provincial scale from 2020-2100 within the framework of shared socioeconomic pathways (SSPs). The provincial output value is re-allocated to grids at a 0.1 degree resolution based on the gridded land use and population. There are 15 files in total, which are saved in the form of. CSV. Each file is a combination of an industry sector and an SSP. In each file, the first and second columns are the longitude and latitude of the grids, respectively, and the first row is the year. Starting from the third column and the second row, the output value is given as a two-dimensional matrix in units of yuan.

本数据集采用柯布-道格拉斯生产函数（Cobb-Douglas production function），在共享社会经济路径（shared socioeconomic pathways, SSPs）框架下，对2020至2100年中国省域尺度下第一、第二、第三产业的产值进行投影预测。基于网格化土地利用与人口数据，将省域产值重新分配至0.1度分辨率的网格单元中。数据集共包含15个文件，均以CSV格式存储。每个文件对应一个产业部门与一种SSP情景的组合。各文件中，第1、2列分别为网格的经度与纬度，第1行为年份序列；自第2行第3列起，以元为单位的产值以二维矩阵形式给出。
