我国企业税收负担及其承担的"五险一金"缴费率与企业全要素生产率之间存在"倒 U 型"关系.门槛效应分析表明,在企业税收负担高于门槛值 9.32%～10.05%区间、"五险一金"缴费率高于 25.21%～26.82%区间时通过政策调节降低其占比有利于实现 TFP 水平的提升.在进行安慰剂检验、替换核心变量运算方法等检验后,结论依旧稳健.异质性分析表明企业所有制结构、规模、资本密集度和区域差异对研究结果有所影响.
TAX BURDEN OF ENTERPRISES,CONTRIBUTION RATE OF"FIVE INSURANCES AND ONE FUND"AND TOTAL FACTOR PRODUCTIVITY OF ENTERPRISES
There is an inverted U-shaped relationship between the tax burden of Chinese enterprises and the payment rate of"five in-surances and one fund"and the total factor productivity of enterprises.The threshold effect analysis shows that when the tax burden of enterprises is 9.32%～10.05% higher than the threshold value When the payment rate of"five insurances and one fund"is higher than the range of 25.21%～26.82%,reducing its proportion through policy adjustment is conducive to the improvement of TFP level.After the placebo test and the replacement of the core variable operation method,the conclusion is still robust.Heterogeneity analysis shows that differences of enterprise ownership structure,scale,capital intensity and region have an impact on the research results.
