Theory of Competitive Advantage: Economic Growth Orientation presents a mezzoeconomic framework for understanding economic growth through the dual role of regional governments and enterprises. Chen Yunxian and Xu Lei critique comparative advantage theory and firm-centered accounts of competitive advantage, arguing that long-term development is shaped by enterprise competition at the microeconomic level and intergovernmental competition at the mezzoeconomic level. The volume introduces an original "9-in-3" competition framework , the DRP Model , a four-stage theory of regional economic growth , and a gradient transference model for analyzing regional government competitiveness and regional competitive advantage. A dedicated chapter presents Shenzhen as a case in China's regional economic development. With 23 figures , glossary, references, and index, the work is recommended for academic libraries supporting economics, development economics, regional economics, public policy, industrial economics, China studies , and comparative political economy .
