Employment impacts of renewable energy policies in China: A decomposition analysis based on a CGE modeling framework

Abstract

Employment impacts are one of the most important social impacts associated with the development of renewable energy, and are also one of the key concerns for policy makers designing renewable energy policies. Current studies tend to focus on the direct job changes in renewable sectors per se and on the indirect job changes along value chains of renewable energy, therefore depicting a picture of prosperity with large amounts of “green jobs”. However, the induced job changes in other sectors that are not directly in the value chains but are still influenced by electricity price changes and related financial resource transfers have usually been neglected, resulting in an incomplete and potentially biased understanding of this specific category of social impact. By using a computable general equilibrium (CGE) model of China that incorporates detailed renewable power generation technologies and considers labor market imperfections, our study tries to fill this gap and quantifies the full scope of job changes (direct, indirect and induced) brought by renewable energy development in China. Results show that per 1 TW h expansion of solar PV and wind power would create up to 45.1 thousand and 15.8 thousand, respectively, direct and indirect jobs in China. However, the scale of induced job changes is quite significant and may even lead to net job losses in the whole economy in some cases. We have further revealed the sectoral contributors to total job changes. In all, there are no assured conclusions on the occurrence of green jobs when developing renewable energy. The impacts are highly dependent on the species of renewable energy, the financing mechanisms for renewable subsidies, and the scopes of employment impacts. We suggest that full-scope employment impacts should be carefully considered and the detailed supporting policies should be carefully designed by decision makers when promoting renewable energy.
