省际粮食贸易隐含污染与环境比较优势研究
Embodied pollution and environmental comparative advantage of China's inter-provincial grain trade
摘要
Abstract
In order to coordinate the contradiction between grain production,trade and non-point source pollution,and to achieve green agricultural development and regional win-win interests,based on the calculation of inter-provincial grain trade volume,this paper uses grey water footprint method to calculate inter-provincial nitrogen pollution and pollution intensity,and constructs the environmental comparative advantage network of food trade nitrogen pollution.The results show that the pattern of China's inter-provincial grain trade network has changed from"strip"to"cluster",and the trend of trade centralization is obvious.The implied pollution and pollution intensity of inter-provincial grain trade showed a decreasing trend,but regional differences significantly aggravated environmental inequality.The network of inter-provincial environmental comparative advantage showed an olive pattern of"small at both ends and large in the middle".The regions with the smallest environmental comparative advantage were concentrated in North China,and the largest was Heilongjiang.关键词
