企业性质、研发效率与全要素生产率——基于中国工业企业微观数据的实证检验

以企业性质影响全要素生产率的理论机制为基础,利用中国工业企业微观层面数据就企业性质通过研发效率作用于全要素生产率的假说进行实证检验。结果发现:内资企业性质降低了研发投资效率,从而抑制了全要素生产率的提升,其中国有企业的阻碍作用最为明显;外商投资企业性质则有利于发挥研发投资的功能,对全要素生产率具有显著的正效应。来自轻重工业分组的回归结果表明,不同行业中企业性质的影响存在一定差异,轻工业国有和私营企业性质对全要素生产率的作用不显著,而重工业企业与总体样本的结果较为一致。

Enterprise Ownership,R ＆amp; D Efficiency and Total Factor Productivity-Empirical Analysis Based on Industrial Firm-Level Data of China

Based on the theoretical mechanism and industrial firm-level data of China ,the impacts from enter-prise ownership on total factor productivity through R＆amp;D efficiency are tested .The results show that domestic enterprises ow nership decreases R＆amp;D efficiency ,so as to restrain the improvement of total factor productivity , in w hich state-ow ned ow nership has an apparent negative impact .Foreign enterprise ow nership is in favor of R＆amp;D investment ,so as to improve total factor productivity .According to the divisions by light and heavy in-dustries ,the empirical results show that enterprise ow nership in different industries has different impacts .T he impacts of state-ow ned and private enterprises in light-industries are not significant ,w hile the results of heavy-industry are the same as the total sample .
