Abstract：
It is a new requirement for the structural reform of the agricultural supply side to explore the advantages of agglomeration of the main producing areas and to realize the improvement of quality and efficiency of agricultural production. Using the survey data from 306 vegetable farming specialty villages in Huang-Huai-Hai region and Bohai Economic Rim, this paper adopts the theory of industrial agglomeration and the Simultaneous Equations Model in a theoretical analysis of an empirical test on the interactive mechanism between Marshall externalities of industrial agglomeration and agricultural productivity. The main conclusions are: The increase of industrial agglomeration promotes the land productivity through Marshall externalities, and indirectly promotes labor productivity, while the increase in labor productivity will improve the agglomeration degree through cumulative effect. Forming a virtuous circle of interactive promotion these three factors promote the sustainable development of China’s vegetable industry.
