Social Security Contributions and Corporate Flexible Employment:A Quasi-natural Experiment from the New Social Security Regulations
Flexible employment is an emerging employment pattern that improves the efficiency of the labor market.Based on the hand-collected flexible employment data of A-share listed firms from 2015 to 2021,using the new 2018 social security regulations as a quasi-natural experiment,this paper examines the impact of new social security regulations on firms'flexible employment using DiD method.It is found that this reform significantly promotes the flexible employment of firms,and this effect is more prominent among firms with weak bargaining power of labor,difficulty in cost adjustment,and lower position in the product market.Mechanism tests show that the new social security regulations increase the level of firms'liquidity constraints and affect their flexible employment decisions by reducing labor demand and promoting factor substitution.This paper provides policy implications for further optimizing the social security system and improving the structural"tax cuts and fee reductions".
