Abstract

Robot-centered intelligent manufacturing is leading a new round of technological revolution and industrial change. Existing studies have neglected the impact of air pollution, a non-monetary factor, on firms' intelligent manufacturing transformation (FIMT). Using matched samples from China's industrial enterprise database and China's customs database, and based on enterprises' “machine replacing human” strategy, this paper reveals the facilitating effect of air pollution on FIMT. The robustness estimation results after endogeneity treatment, replacing the core variables, changing the clustering level, removing the policy influence, avoiding the interference of domestic robots, changing the estimation strategy, and restricting the import trade mode still support the conclusion. The mechanism by which air pollution accelerates FIMT lies in the first: the factor substitution effect of rising labor costs due to air pollution. The second is the skill-capital complementarity effect due to increased firms' human capital investment induced by air pollution. The third is the intelligent investment effect due to increased economic policy uncertainty induced by air pollution. In addition, air pollution accelerates FIMT more significantly in non-state-owned firms, high labor-intensity industries, and regions with high population aging. This paper argues that there is no conflict between environmental governance and intelligent manufacturing transformation. Air pollution and “machines replacing humans” in the labor market efficiency and fairness issues need attention.
