基于生态补偿的国家重点生态功能区居民可持续生计影响研究

在对可持续生计的理论机理进行分析的基础上,将熵值法和极差标准化法相结合,确定各指标权重并进行标准化,得到国家重点生态功能区居民生计资本、生态补偿政策以及可持续生计能力的量化值,并利用可行的广义最小二乘法进行实证分析。研究发现,五种生计资本对居民的可持续生计具有正向影响,且影响程度的排序为人力资本>金融资本>社会资本>自然资本>物质资本。生态补偿政策对国家重点生态功能区居民可持续生计能力也具有正向影响,说明生态补偿政策有利于改善当地收入状况,巩固脱贫攻坚成果。最后,生态补偿政策还可通过与人力资本、金融资本、物质资本和自然资本的交互作用,促进国家重点生态功能区居民可持续生计能力的提高。

The Impact of Sustainable Livelihood of Residents in the National Key Ecological Function Areas Based on Ecological Compensation

Based on the analysis of the theoretical mechanism of the sustainable livelihood,the article combines the entropy method and range standardization method to determine the weight of each index and standardize the weight value,so as to obtain the quantitative value of livelihood capital,ecological compensation policies and sustainable livelihood capacity of residents in the national key ecological function areas,and then using the feasible generalized least square method for empirical analysis.The study finds that,firstly,five kinds of livelihood capital have positive impact on the sustainable livelihood of residents,and the order of the degree of impact is human capital>financial capital>social capital>natural capital>physical capital.Secondly,the ecological compensation policy also has a positive impact on the sustainable livelihood ability of residents in national key ecological functional areas,indicating that the ecological compensation policy is conducive to improving local income and consolidating the achievements of poverty alleviation.Finally,ecological compensation policy can also promote the improvement of sustainable livelihood of residents through the interaction with human capital,financial capital,physical capital and natural capital.
