中国要素价格相对扭曲对企业技术创新影响的研究——基于微观企业数据的Probit检验

The Effect of Factor Price Distortion on Firms' R&D Activities in China:a Probit-Model Examination of Firm-Level Data

本文基于2005-2007中国工业企业微观企业数据,利用LP半参数估计方法计算了国有企业的要素价格相对扭曲程度。并在理论上分析了不同所有制企业所呈现出的不同程度的劳动力价格相对低估对不同类型企业研发创新动机产生的抑制作用。在此基础上,进一步利用2005-2007年中国工业企业微观数据构建基于面板的二元选择模型,验证了劳动力价格相对低估对企业研发创新活动的影响。结果表明,源于制度性因素所造成的,广大民营企业面临的更为严重的劳动力价格的相对低估情况严重抑制了企业的创新活力,放松对民营企业的体制性束缚是激发企业研发动机的关键。

In this paper, we calculate the relative distortion of factors price of Chinese companies using the LP semiparametric regression model and the panel data of industrial enterprises in China from 2005 to 2007. Based on the results, we analyze the affection of the relative underestimate of labor price on R＆D activities among the enterprises of different model to examine the affection using the same panel ownership theoretically. We also establish a probit data as mentioned before. The results show that the R＆D activities of the private enterprises which are facing more severe environment of the relative underestimate of labor price because of the institutional constraints are restrained; the key factor of the remission of distortion and the incentive of R＆D is relaxing the institutional constraints.
