This system aims to bring about the most effective coordination of social, economic and ecological factors in agricultural practices. Key approaches include ecological planning at the landscape level, cycling system design at the ecosystem level, and the re-establishment of the importance of biodiversity. The social and economic environment favoured for ecoagriculture is important in order to enable its development. For the social environment, it is important to set up the necessary moral standards involved through educational, legislative and evaluation systems. For the economic environment, efficient government subsidy policies, an effective market system to deal with pollutant discharge, and efficient markets for the sale of ecologically-friendly products.展开更多

In this paper, we study the transboundary industrial pollution control problem in the Beijing-Tianjin-Hebei region in the context of industrial relocation. Firstly, we construct an economic model of pollution control with relevant variables such as environmental tax and environmental damage coefficient. Secondly, we solve the economic contributions by using the proportional split-off solution. Finally, we compare the optimal relocation quantity and welfare functions in both cooperative and non-cooperative cases. Our research finds that: 1) The optimal strategy is closely related to utility coefficient, environmental loss coefficient and incentive intensity coefficient.2) The welfare function and the optimal relocation quantity in the cooperative case are significantly greater than those in the non-cooperative case. Based on the analysis, some suggestions are provided for transboundary industrial pollution management.展开更多
