| 摘 要： | 生态移民政策评估是多学科领域的热点问题,而机理研究是其关键环节。本研究通过构建“生态移民政策→生计资本→收入”分析框架,以生计资本为中介变量,选择形成型指标建立结构方程模型分析生态移民政策对收入的影响机理,采用偏最小二乘回归方法估算路径系数,测算生态移民政策对收入的直接效应、间接效应和总效应,验证生态移民政策影响收入作用机理的有效性。陕南和宁夏的生态移民分别是城镇化社区安置和新农村安置的典型,通过实证分析两地生态移民政策作用机理,针对关键生计资本提出优化措施,以增加农户生计资本并长效促进收入提高。研究表明：两种类型的生态移民政策通过人力资本、社会资本、金融资本和物质资本对农户收入均有正向作用,但是影响大小略有区别。陕南地区的生态移民政策通过社会资本改善农户收入的作用最强,人力资本次之,金融资本和物质资本相对较小;宁夏地区的生态移民政策通过金融资本改善农户收入的作用最强,人力资本次之,社会资本和物质资本相对较小,自然资本具有微弱的负向影响。总体而言,生态移民政策的实施能有效促进农户生计资本存量的积累,进而产生稳定可持续的收入流量。

| Abstract: | Policy assessment of ecological migration is a heated issue in a multidisciplinary context, and the impact mechanism lies on the key position. By constructing the analytical framework of Ecological migration policy → livelihood capital → income and using Structural Equation Modeling with Formative Indicators, a structural equation model with livelihood capitals as mediator variables was adopted to explore the impact mechanism of ecological migration policy on household income. Through the Partial Least Squares regression method, path coefficients were calculated to estimate the direct, indirect and total effects between the ecological migration policy and income, and then verify the effectiveness of the mechanism. As the representatives of urban community and new village resettlement, the migration households in southern Shaanxi and Ningxia were selected as sampling to conduct an empirical analysis of the mechanism of ecological migration, and to put forward optimization measures to improve farmer livelihood capital and increase household income. We found that ecological migration policy in southern Shaanxi and Ningxia has a positive effect on the improvement of farmer income through human capital, social capital, financial capital and physical capital, with a slight difference in each path. In southern Shaanxi, the most important way to improve household income is using social capital, the second is human capital; financial capital and physical capital are relatively small. In Ningxia, the sequence of importance is financial capital, human capital, social capital physical capital, while natural capital plays a negative role. In general, ecological migration policy can effectively accumulate the stock of farmer livelihood capital and then produce a stable and sustainable income flow. |
