本文基于“柯布-道格拉斯生产函数”推导出企业社保缴费对劳动力就业影响的决定方程,利用2007~2014年中国沪深两市419家制造业上市公司的财务数据,实证研究我国企业社保缴费对劳动力就业的影响效应。结果发现,企业社保缴费对劳动力就业存在显著的挤出效应,即企业社保缴费率每上升1%将挤出企业雇佣人数约6.9%的水平,而这一挤出水平需要人均GDP增长约0.04个百分点才能弥补。进一步研究发现,企业的所有制性质是影响企业社保缴费就业挤出效应差异的重要原因,其中国有控股企业的社保缴费对劳动力就业具有明显的挤出效应,而这种挤出效应并没有在民营控股企业中发现。
Based on “Cobb - Douglas production function ”, this paper deduces the determinants of the contribution of social security contribution to the employment of the labor force. Using the financial data of 419 manufacturing listed companies in Shanghai and Shenzhen from 2007 to 2014, this paper empirically studies the social security Effect of Contribution on Labor Force Employment. As a result, it is found that there is a significant crowding-out effect on labor force employment by social insurance contributions in enterprises, that is, an increase of 1% in the social insurance contribution rate of enterprises will squeeze out about 6.9% of the employment of enterprises, and this level of extrusion requires GDP growth of about 0.04 Percentage point to make up. Further research finds that the nature of ownership of enterprises is an important reason that affects the difference of employment crowding-out effect of social security contributions. The contribution of social security of state-owned holding enterprises has obvious crowding-out effect on the employment of the labor force, and this crowding-out effect is not in private holding Found in the business.
