Government cooperation, market integration, and productivity: evidence from China.

This paper examines the causal effect of regional market integration on firm productivity through the use of 2001–2008 firm-level microdata in China. The research design relies on a regression discontinuity design based on China's Pan-Pearl River Delta (PPRD) regional cooperation policy. The results indicate that the PPRD regional cooperation policy increases the total factor productivity (TFP) of firms by 6% on average. The positive impact of the PPRD regional cooperation policy on TFP is greater for private firms, large firms, and labour-intensive firms. Exploring the mechanism through which regional cooperation increases firm TFP, we find that the PPRD regional cooperation policy improves firms' productivity primarily by expanding the scale of firms, promoting technological innovation, and optimizing the allocation of factors. The study findings deepen our understanding of productivity improvement from the perspective of the market environment. [ABSTRACT FROM AUTHOR]
