The article explores how the structure and position of China's domestic market network impact regional economic growth. By analyzing data from 29 provinces between 1997-2011, the study found that the evolution of market relations and network position significantly influence economic growth. Before 2004, increased market integration hindered growth but after 2004, it promoted growth and reduced regional disparities. Improving a region's network position can shift from inhibiting to promoting economic growth. To enhance a region's position, local governments should reduce market barriers, connect with key markets, and develop unique advantages.
