Environmental Regulation, Technological Innovation, and Export Competitiveness: An Empirical Study Based on China's...

Area of Science:

• Environmental Economics
• International Trade
• Industrial Organization

Background:

• Developing nations face challenges balancing environmental protection with manufacturing competitiveness.
• Effective environmental regulation is crucial for sustainable development and international trade.
• China's manufacturing sector's export competitiveness is a key area of study.

Purpose of the Study:

• To investigate the impact of environmental regulation on China's manufacturing export competitiveness using export value added.
• To empirically test the Porter hypothesis and examine intra-industry heterogeneity.
• To explore the mechanisms through which environmental regulation influences technological innovation and export competitiveness.

Main Methods:

• Application of the Porter hypothesis for empirical analysis.
• Analysis of export value added to measure competitiveness.
• Investigation of intra-industry heterogeneity across pollution levels.
• Exploration of technological innovation mechanisms (independent R&D vs. technology introduction).

Main Results:

• Environmental regulation has a non-linear, U-shaped promotion effect (approx. 2%) on export competitiveness, contingent on prerequisites.
• Significant intra-industry heterogeneity observed, with stronger effects in heavily polluting industries.
• Independent R&D is negatively impacted by compliance costs, while technology introduction benefits from innovation offsets.

Conclusions:

• Environmental regulation can enhance manufacturing export competitiveness, but requires specific conditions to be met.
• Policy design must consider industry-specific pollution levels and technological innovation approaches.
• Findings provide insights for sustainable environmental policies and foreign trade strategies.
