毗邻沙漠地区微分博弈模型与宏观环境治理策略研究

工业化发展导致了脆弱的土地进一步沙漠化,沙漠地区政府应综合考虑经济发展与土地沙漠化导致的生态质量降低。通过构建两个沙漠化地区微分博弈模型,研究了两个地区的沙漠治理问题。研究结果表明,提高工业生产排放技术或沙漠治理技术均能够提高均衡经济产出水平,在工业生产收益系数较高的情况下也能够提高沙漠治理投入水平,并且两种技术提高存在交互效应;只有对生产排放技术水平和沙漠治理技术水平较高的地区,延长地方政府领导任期有利于沙漠治理;实现沙漠完全治理情况下控制土地再沙化的治理投入低于控制沙漠稳定在一定规模的治理投入。

Study on Differential Game Model and Macro-environmental Governance Strategy in Adjacent Desert Areas

The development of industrialization has led to the further desertification of fragile land, and governments in desertification areas should comprehensively consider economic development and the degradation of ecological quality caused by land desertification. This paper establishes a differential game model for two desertification areas to discuss the desert governance problems, the results show that improving industrial production emission technology or desert control technology can increase equilibrium economic output level, and they can also increase the investment level of desert control when the economic return coefficient is high, and there is an interactive effect between the two technologies; In areas with high level of production emission technology and desert control technology, extending the term of leadership of local governments leaders is more conducive to desertification control; The investment of controlling land re-desertification in the condition of completely combating desert is lower than that of controlling desert stable in a certain scale.
