技术创新路径对涉农企业效率的影响

Study of Effects of Technical Innovation Paths on Efficiency of Agricultural Enterprises

基于2006—2014年面板数据,通过构建随机前沿生产函数模型来研究引进国外技术、消化吸收技术、购买国内技术和改造升级技术4种技术创新路径对我国涉农企业效率的影响,并在此基础上研究不同技术创新路径对不同性质涉农企业效率的影响。研究结果表明:我国涉农企业逐渐由劳动密集型转变为资本密集型;消化吸收技术创新路径对涉农企业效率影响具有稳定的正向效应,引进国外技术、购买国内技术创新路径对涉农企业效率影响由不显著的正向效应逐步转变为显著的负向效应;消化吸收技术、改造升级技术创新路径对内资涉农企业、港澳台投资涉农企业分别具有显著的正向效应和显著的负向效应,且改造升级技术创新路径对港澳台投资涉农企业效率的影响小于对内资涉农企业的影响。

On the basis of stochastic frontier production function, this study focuses on exploring the varied effects on agricultural enterprises by the distinctive selection among four technological innovation paths which are international technology import, technology assimilation, domestic technology purchase and technology update through the panel model analysis with data sources from 2006 to 2014. The research outputs propose that China＇s agricultural enterprises gradually change from the labor - intensive to capital intensive ; technology assimilation imposes the stable positive effects on the efficiency of the enterprises; international technology import and domestic technology purchase are turning to be significantly negative from being insignificantly positive. Meanwhile, technology assimilation and technology update are significantly positive to enterprises which are funded from domestic and less significantly negative to Hong Kong, Macao and Taiwan enterprises.
