Abstract: The expansion of population urbanization is the engine of the development of agricultural produces circulation industry，and efficiency improvement of agricultural produces circulation industry is a strong guarantee for urban population expansion. So，the coupling level of the two in time and space affects the quality of regional economic coordinated development. Based on the DEA-Malquist index and the coupling models, this paper measures industry′s technical efficiency of 31 provinces from 2005 to 2015, variation of total factor and its decomposition, and the coupling with the level of population urbanization. This study shows low technical efficiency of agricultural produces circulation industry and high growth of population urbanization coexist; technological progress, rather than technical efficiency, has promoted the total factor productivity growth of agricultural produces circulation industry; the coupling degree between population urbanization growth and the variation of agricultural produces circulation industry efficiency is developed from low level to high level in rotation of time and space, but the difference between provinces is obvious. Therefore, it is necessary to make full use of the spillover effects of the cities and improve the technical efficiency of agricultural produces circulation industry in the low coupling zone and accelerate the pace of urbanization in the high-coupling zone. In addition, we should promote the integration of e-commerce to optimize the circulation link of agricultural produces.

Key words: population urbanization, agricultural produces circulation industry, technical efficiency, Spatial-temporal Coupling
