要素积累、人力资本与农业环境效率间门槛效应研究——低碳约束下面板门槛模型检验

农业环境治理问题不仅关系到农业经济的可持续发展,更关系到农户的身体健康.基于2000-2013年中国30个省级行政单位的均衡面板数据,建立以要素积累为门槛变量的面板门槛模型,检验了农村人力资本对农业环境效率提升非均衡变化的门槛效应.研究结果表明:人力资本与农业环境效率间会因为经济发展和物质资本积累水平的不同而呈现出显著的双门槛区间效应,表现为从经济低发展区到高发展区,人力资本与农业环境效率提升间具有显著的“反N型”特征趋势,而物质资本从匮乏区到丰富区,人力资本与农业环境效率提升间呈现明显的“倒U型”趋势特征.应加快确立和制定农业环境政策的“优化经济发展水平、物质资本和人力资本积累间结构”的导向和工具.

Research on threshold effect on the relationship between factor accumulation, human capital and agricultural environment efficiency

Agricultural environment governance issues directly affect the sustainable development of rural economy and farmers'' health.Based on balanced panel data of China''s 30 provinces from 2000 to 2013,this paper takes the factor accumulation as threshold variables to establish panel threshold regression model,in order to test the unbalanced threshold effect on rural human capital to improving the agricultural environment efficiency.The results show that between human capital and agricultural environment efficiency there has a significant dual threshold range effect relying on economic development and material capital accumulation.Human capital and agricultural environment efficiency ascension reveal a significant "inverse-N type" trend characteristic from the low area to the high-risk area of economic development.Human capital and agricultural environment efficiency ascension reveal an obvious "invert U-type" trend characteristic from the shortage area to the abundant area of material capital.Agricultural environment policy should reflect the guide of optimizing the structure in economic development level,physical capital and human capital accumulation.
