Measurement of urban total factor productivity and analysis of spatial spillover effect of factors in China
The spatial spillover effect of urban factors plays an important role in the high-quality development of urban economy and regional coordinated development in China.Based on the rational construction of CD production function embedded in general nested spatial econometric model,this paper uses the data of 258 cit-ies at prefecture level and above in China from 2000 to 2018 to measure the urban total factor productivity in-corporating spatial spillover effect of factors to represent high-quality development of urban economy in China.At the same time,this paper uses appreciate production function embedded in general nested spatial economet-ric model to decompose the spatial spillover effect of capital and labour factors of specific cities and 5 major urban agglomerations,and explore the radiation driving capacity of specific cities and 5 major urban agglomer-ations to improve current situation of regional coordinated development in China.The results show that:1)In terms of timing development,the overall urban total factor productivity in China has decreased slightly,but there is a gradual rising trend after 2017.In terms of spatial evolution,the total factor productivity in cities in southern and northern China has changed significantly,while the total factor productivity in eastern and west-ern cities remains stable.2)The result of measurement of urban total factor productivity with spatial spillover effect of factors is 0.4663 higher than that of those without spatial spillover effect of factors,indicating that spatial spillover effect of factors has a remarkable positive effect on urban total factor productivity.3)Among the specific cities,the spatial spillover effect of factors of national central cities,and cities in the Bohai Bay,the Yangtze River Delta and the Pearl River Delta is strong,while the spatial spillover effect of factors of central and western cities is weak.Among the 5 major urban agglomerations,the spatial spillover effect of factors in Yangtze River Delta urban agglomeration is higher,while that in Chengdu-Chongqing urban agglomeration is lower.
