How to alleviate the pressure of resources and the environ-ment and to achieve the sustainable development of the economy has become a global agenda.China＇ s economy growth has been rapid for decades since the reform and opening up policy,but this has also been a great drain on China＇ s resources and the environment, which is an ur-gent problem to tackle. In recently years, the Chinese government has launched many environ-mental policies in the hope of encouraging technological innovation to guarantee the sustain-able development of the economy. However, research suggested that technological innovationis negatively correlated with environmental policies in most scenarios. In some cases, the num-ber of technological innovation decreases after policies take effect and increases after a whilelike a U - curve. In order to solve this problem, I decided to analyze the panel data from 80provinces in China between 2008 and 2014 and conclude that local governance can implementenvironmental regulations while having a positive impact on the technological innovation inenterprises. In the conclusion, suggestions are given to local governments on how to better en-force environmental policies.展开更多

In each learning step, all agents commit to select the global policy to achieve the global goal. We prove this learning algorithm converges given certain restrictions on stage games of learned Q values, and show that it has quite lower computation time complexity than already developed multi-agent learning algorithms for general-sum games. An example is analyzed to show the algorithm＇ s merits.展开更多

In order to find the relationship between the farmers＇ response to the microeeonomic policies and land degradation, the authors surveyed 120 household in three villages in the black soil zone in Heilongjiang Province. Based on the feedback of the questionnaires, the authors established a model to analyze the impact. The results demonstrated that land degradation was impacted by farmers behaviors in the process of the adjustment of agricultural structures in the city of Zhaodong. And the main factors acted on the land degradation were the agricultural labour education level, the transfer of the labour from agricultural production, the price of the agricultural production materials, and the land scale management. The authors put forward some suggestions for sustainable agriculture based on the analysis on the topic.展开更多
