摘要
影响农业科技进步的两个主要因素是技术追赶效应及农村劳动力人力资本水平,其中分布方差是分析人力资本对科技进步及经济增长影响的新视角。本文针对文献中的争议,根据Benhabib-Spiegel理论框架检验农村劳动力人力资本及追赶效应对农业科技进步的影响。考虑到各省份间农业科技进步可能存在空间相关性,因此本文建立空间计量经济学模型,基于我国2000年-2010年间的省级面板数据进行实证分析。结果表明:2000年-2010年间,我国各省份农业科技进步水平存在显著的空间相关关系,并且空间相关性在逐年增大;人力资本均值及分布方差对农业科技进步有显著的正向影响;农村劳动力的人力资本水平与受教育年限间并非为线性关系;技术追赶效应对农业科技进步水平有正向影响;财政支农也显著影响了农业科技进步水平。本文认为要逐步转变农村地区仅强调义务教育重要性的现状,应该通过发展职业教育、对农民合作经济组织的发起人或生产大户等农业生产的带头人进行培训等途径适当扩大人力资本分布方差。
Two major factors lhat affect the progress of agricultural science and technology are the technology catching-up effect and rural labor human capital, and dispersion is a new perspective to analyze the influence of human capital on science and technology. progress and econonnc growth. According to the Benhabib-Spiegel theoretical framework and aiming at the dispute of previons studies, this paper inspects the influence of rural labor human capital and catch-up effect on agricultural science and technology progress. Considering the spatial correlation, this paper makes an empirical analysis based on 2000 -2010 provincial panel data in China by building a spatial econometric model. The results show that： in the period of 2000 - 2010, there is a significant spatial correlation between the agricuhural science and technology of the various provinces, and the spatial correlation increases year by year; human capital dispersion has a significant positive effect on agricultural science and technology progress; human capital and years of education are no linear relations; catch-up effect and financial support for agriculture significantly influence the agricultural science and technology progress level. This paper considers that the current situation of only emphasis on the importance of compulsory education in rural area should be gradually changed by the ways of developing the vocational education and training of cooperative economic organizations sponsor and big providers of agriculture to appropriately expand the human capital dispersion.
