Abstract:

Based on the time series of the gross domestic product and the demographic census of China, and statistical yearbooks in 31 provinces (China mainland), the labor participation rate, capital output elasticity and total factor productivity were localized in order to build the Cobb-Douglas model under the Shared Socioeconomic Pathways (SSPs) framework. The changes of national and provincial output value of the primary, secondary and tertiary industries were analyzed for the first half of the 21st century. The results show that: (1) The output value of three industries in China will be different significantly under SSPs. The primary and secondary industries show the same trend, but output value of the latter will be higher than that of the former. And they will increase under SSP1, SSP2 and SSP5, while decline under SSP3 and SSP4. The tertiary industry will continuously grow under all SSPs. (2) The growth rate of output value of three industries will decrease. The differences of industrial growth rates and material and cultural need lead to the gradual decrease of contribution of the primary and the secondary industries to economy, while the increase of contribution of the tertiary industry. (3) Different social and economic development policies have significant impacts on the provincial output value of three industries. Spatially, the output value of the primary, secondary and tertiary industries is high in the east but low in the west in China in 2020-2050. By the mid-21st century, increase in the output value in the eastern region will be the highest for three industries. The increase of the output value of the primary and secondary industries in the northeast region will be the lowest, while that of the tertiary industry in the western region will be the lowest. In 2050, contribution of the primary industry to provincial GDP will be less than 8% and that of the tertiary industry will be higher than 60% generally. Meanwhile, share of the secondary industry will be 25%-30%. The contribution of the output value of the tertiary industry to GDP in the eastern region will be always higher than that in the west, and industrial structure of the eastern region is more reasonable.

Key words: Cobb-Douglas model, Output value from industries, Shared Socioeconomic Pathways (SSPs), China, Province
