【主题】Do state-owned enterprises undertake more social responsibilities? An empirical analysis of pollution control
Though state-owned enterprises (SOEs) are less economically efficient than their peers, one of the possible reasons is that they internalize more externalities and thus assume more social responsibilities. This paper compared the environmental performance of SOEs with private-owned enterprises (POEs). Based on the firm-level database from 1998 to 2007, we find that POEs produce more, remove less and thus emit more sulfur dioxide (SO2) than do SOEs by 5.31%, 6.41% and 7.68%, respectively. To mitigate endogeneity problems, we use the difference-in-differences (DID) method to explore how the environmental performance of enterprises will change after ownership changes. The results show that the privatization of SOEs will lead to increases in SO2 production and emissions by 7.61% and 8.18%, respectively. By comparing the results of the government-controlled pollutant SO2 and the non-controlled pollutant nitrogen oxides (NOx), we find that SOEs are more likely to react favorably to government regulations and thus have better environmental performance.
