Abstract

To guarantee the safety of metropolitan cities' vegetable supply is not only the important basis of economic development and social stability, but also a key part of the national food security strategy in China. Based on the practical data of Beijing, Shanghai and Hangzhou, this paper employs grey correlation dynamic analysis (hereafter GCDA) method to comparatively analyze the influence factors that impact the three cities' vegetable production in the natural, technical, and economic aspects, such as vegetable sown areas, yearly rainfall, average air temperature, sunshine hours, yield per area, effective irrigation areas, total agricultural machinery power, rural electrical power consumption, amount of chemical fertilizer consumption, total costs of unit vegetable production, net profits of unit vegetable production, labor number, urbanization and industrial development levels. The analysis results show that different factors have different influences on the vegetable production for the metropolitan cities in different regions. Especially, the following factors, such as the vegetable sown areas, total power of agricultural machinery, reasonable fertilizer consumption, effective irrigating areas, and sufficient labor number, have higher impacts on the vegetable production capability of the three major cities compared with other factors. In the end of this paper, the different countermeasures for the different metropolitan cities are put forward according to the analysis results.
