摘要:

本文利用我国2008年~2013年31个省市、自治区的面板数据,通过单位根检验和Hausman检验确定回归模型的影响形式,同时,利用F检验判定需要拟合的回归模型形式,建立变截距固定效应模型,以分析高科技产业的研发行为对产业绩效的影响。研究结果表明,研发经费的投入能够有效提升产业绩效；然而,研发人员数量的投入却削弱了产业绩效；目前,我国高技术产业的研发投入显现出非均衡状态。最后,基于估计结果我们有针对性地提出了相关的政策建议。

Abstract:

Panel data of 31 provinces from 2008 to 2013 are tested as unit root, and effect forms of regression model are set through Hausman Test. F-test is used to judge the demanding matching model forms, and variable-intercept models are established to analyze the influence of research and development behavior of high technology industry in industry performance. The research shows that input of research and development expenditure promotes the industry performance; the number of research and development staff can reduce the industry performance; national research and development input of high technology industry is still unbalanced; and at last, some policies and suggestions are proposed.
