Abstract:

Based on value-added model, social network analysis and dynamic panel model, this paper conducts a sample survey of 40470 city-city units consisting of 285 prefecture-level cities and above from 2003 to 2017, and discusses the evolution of China's regional economic synergetic network and the reasons for its formation. The results show that: (1) The regional economic synergetic network density has experienced three short cycles and two gaps. The first short cycle refers to the regional economic synergetic network density changing from high density in 2003 to low density in 2009. The other two cycles refer to 2009-2013 and 2013-2017. The gaps refer to the low densities between every two cycles in 2009 and 2013. Among all the synergetic movements, the synergic movements with eastern cities are stronger than the those with central and western cities. That is, there is a significant eastern oriented characteristic with high-intensity synergic movements located in eastern cities. (2) The regional economic synergetic network has transferred from a pentagram coverage pattern to a fan-shaped pattern with the Pearl River delta region and the Yangtze River delta region as the two cores. Then the regional economic synergetic network has changed to a fan-shaped pattern with the Pearl River delta region as the core. Finally, the regional economic synergetic network has formed a multilayer nested pattern. With the evolution of the regional economic synergetic network, there is a significant cross-regional characteristic with geographical distant synergies across the eastern, central and western regions. (3) As for the reasons for the regional economic synergetic network formation, comparative advantage, economic contact and industrial system are the three main driving forces that determine the network evolution. The virtuous circle of the comparative advantage, economic contact and industrial system in eastern cities leads to the characteristic of the east orientation. Cross-regional synergic movements are beneficial to the integration of regional differentiation comparative advantage, the reduction of the risk of resource contention and redundancy construction, and the formation of an efficient industrial division of labor system and cross-regional synergetic network.
