This study uses the China Private Enterprise Survey (CPES) data and the national census data to construct a double difference model (DID), investigating the impact of rising labor costs on private firms' innovation investment. The study finds that rising labor costs significantly increase private firms' R&D investment, especially for larger private industrial firms.
This paper constructs a double difference model (DID) based on the China Private Enterprise Survey (CPES) data over the period 1995-2019, combined with the 2005 national census data and considering the policy shock of the implementation of the Chinese government's Minimum Wage Regulation in March 2004, to investigate whether rising labor costs promote private firms' innovation investment. Robustness tests are conducted using placebo tests and event study methods. The study finds that (1) rising labor costs significantly increase private firms' R&D investment and that this effect has significant lag and cumulative effects; (2) private industrial firms (especially above-scale private industrial firms) are more affected by rising labor costs than other private firms and have more incentives to increase innovation investment; and (3) innovation investment of below-scale private industrial firms is not significantly affected by rising labor costs.
