Market Integration and Regional Innovation in China: Evidence from the Yangtze River Delta Region

Abstract

Market integration is an important tool for China’s regionally coordinated economic development. At the same time, China is implementing an innovation-driven development strategy. Therefore, the way the market integration affects regional innovation is of great significance to analyze this problem. The panel data of 27 cities in the Yangtze River Delta region in China with the highest degree of economic integration from 2009 to 2018 are used to investigate the impact of market integration (MI) on regional innovation (RI). The main findings are as follows: the first-order lag term of RI is significantly positive, and RI has certain path dependence. In this regard, MI has a positive impact on RI and promotes RI. The estimated coefficient of MI is significantly positive and has a positive impact on RI and promotes RI. This provides a reference for promoting RI through MI. The contributions of the paper are threefold: (1) This paper examines the impact of MI on RI to provide policy implications for the coordinated development of innovation between regions. (2) The relative price method is adopted to measure the MI, which covers 16 kinds of commodities, covering a wider range than does the traditional method. (3) This paper uses the generalized method of moments (GMM) to test the effect of MI on RI for the first time.

Does COVID-19 Exacerbate Regional Income Inequality? Evidence from 20 Provinces of China

“…The study controls for GDP per capita (RGDP) as it measures the level of regional economic development, which is routinely employed as a determinant of income inequality [45][46][47]. The population (POP) is also included as a control variable as it measures the size of a region, which may also affect income inequality [48]. Additionally, according to previous studies, the industrialization process may also affect income inequality [45,49].…”

A study on the measurement of inter-provincial trade costs in Yangtze River Delta from the perspective of value-added trade and its promotion effect

“…Factor markets' integration level lags far behind commodity markets [6]. In addition to economic factors, various institutional barriers contribute to the distorted development of YRD integration [7]. The uneven development within the Yangtze River Delta region, the severe phenomenon of "vassal economy," the stagnation of market integration and industrial division of labor, the difficulty of synergistic development between mega-cities and super-small cities, the inadequate coordination mechanism of regional interests and the current governmental assessment system, and the failure of Shanghai's core leading role to give full play to the Yangtze River Delta integration are all severe constraints to the development level [8][9][10].…”
