生态供求视角下宁夏生态安全现状与驱动因素分析

Ecological security status and causes of Ningxia from the perspective of ecological supply and demand

论文借鉴国内生产总值核算中的国土原则和产品法计算得到宁夏自治区的生态足迹和生态承载力,从生态供给和生态需求两个角度对区域经济系统运行安全状况进行综合评价,进而构建向量自回归模型以模拟宁夏产业结构变动与生态足迹变动之间的动态响应关系,采用脉冲响应函数探讨其内在冲击响应机制,得到对应的定量分析结果。

Based on the national land principle and product method in the GDP calculation, the paper calculates the ecological footprint and ecological carrying capacity of Ningxia Autonomous Region, and comprehensively evaluates the operational safety of regional economic systems from the perspectives of ecological supply and ecological demand, and then constructs a vector self. The regression model simulates the dynamic response relationship between industrial structure changes and ecological footprint changes in Ningxia. The impulse response function is used to explore its intrinsic impact response mechanism, and the corresponding quantitative analysis results are obtained.
