摘要
利用2008年新《劳动合同法》实施这一具有准自然实验性质的外生政策,以边际劳动生产率为分组变量,运用双重差分的方法,考察了劳动保护对企业创新的影响。研究表明:《劳动合同法》实施后,劳动保护的增强使得低劳动生产率的企业创新显著下降,这种"去芜存菁"的抑制效应在国有企业与民营企业中均存在,但动态趋势变化存在长期和短期的差异;进一步研究发现,劳动保护政策随着市场竞争的减弱、法治治理的改善和薪酬负担的加重,抑制了国有企业的创新,而民营企业受到的抑制效果较弱。研究结论丰富和拓展了中国制度背景下法与创新的文献,并为政策制定提供了经验证据。
Using the implementation of the 2008 Labor Contract Law as a policy of quasi-natural experimentation,this paper discusses the impact of labor protection on enterprise innovation by dividing marginal labor productivity into groups and adopting DID( difference in difference) method. The results are as follows. After the implementation of the Labor Contract Law,the improvement of labor protection makes the innovation of enterprises with low labor productivity decrease significantly. This restraining effect of separating wheat from chaff exists in both state-owned enterprises and private enterprises,but there are long-term and short-term differences in the dynamic trend. Further,this paper examines the specific impact mechanism of labor protection on enterprise innovation,and finds that with the weakening of market competition,the improvement of rule of law and the aggravation of salary burden,labor protection policy has inhibited the innovation of state-owned enterprises,while the restraint effect of private enterprises is weak. The conclusions enrich and expand the literature of law and innovation under the background of Chinese system,and provide an empirical evidence for policy formulation.
