内容提要 | 立足于我国2005-2012年间505个县域贫困区样本,从第一地理外部性和第二地理外部性的视角考察地理资本对我国胡焕庸线上空间贫困陷阱的影响。研究发现:第一,土地资本、物质资本、社会资本、政府行为以及以技术进步都能通过直接效应显著促进自身经济增长;第二,邻居贫困区中的土地资本、物质资本、社会资本以及技术进步都存在正第一地理外部性,而人力资本和地方政府支出则对目标贫困的经济增长具有显著的负第一地理外部性;第三,目标贫困区的耕地资本、物质资本、社会资本、技术进步、地方政府支出都能通过正第二地理外部性显著促进邻居区域经济增长,并且在稳健性检验的GNS模型中,耕地资本、技术进步以及政府支出的对邻居贫困区的正第二地理外部性以及人力资本的负第二地理外部性都处于富有弹性区域。本文的发现可逃离胡焕庸线上空间贫困陷阱提供相应政策启示。 |
Abstract | By using a variety of econometric regression models to analyze the 2005~2012 spatial panel data of 505 poverty regions at the county level in China, this paper analyzes the impact on spatial poverty taps on the Hu Huanyong Line from the perspective of first geographic externalities (FGE) and second geographic externalities (SGE), gets following results: firstly, land capital, physical capital, social capital, local government behavior and technical progress can significantly promote the economic growth of poor areas by means of direct effect. Secondly, land capital, physical capital, social capital and technical progress in neighbor areas have positive FGE, while its human capital and local government spending both have significant and negative FGE. Thirdly, land capital, physical capital, social capital, technical progress and government spending in local area all will promote neighbor areas’ economic growth significantly through positive SGE, and in the GNS model, both the positive SGE from land capital, technical progress and government spending and the negative SGE from human capital are in the elastic region. These findings have a significant enlightenment on escaping spatial poverty taps on the Hu Huanyong line. |
