Research on the Impact of the Eleventh Five Year Plan Policy on Industrial Waste Gas Emissions——Empirical Research Based on Shanghai Enterprises

Abstract

The Eleventh Five-Year Plan constitutes China’s medium and long-term blueprint for building a moderately prosperous society in all respects. To promote sustainable development and alleviate mounting environmental and resource pressures, it imposes new requirements on industrial production. Using pollution and operational data of Shanghai enterprises, this study applies a Difference-in-Diff erences (DID) model to analyze pollutant emission changes before and after the Plan’s implementation. Findings confi rm the policy effectively reduced exhaust gas emissions of Shanghai-based enterprises. Additionally, the study examines post-reduction production performance and the sustainability of enterprises’ green development.
