中国数字经济企业技术创新的区域差异及其时空演进

Research on the Regional Differences and Spatiotemporal Evolution of Technological Innovation in Chinese Digital Economy Enterprises

基于国家统计局最新标准匹配数字经济企业,综合运用多种研究方法,分析中国数字经济企业技术创新的区域差异及其时空演进特征。Dagum基尼系数显示,数字经济企业技术创新的总体差异呈波动上升态势,区域间差异是总体差异的主要来源,贡献率均值达68.31%;从区域内差异上看,仅东部沿海和长江中游地区存在收敛趋势;从区域间差异上看,沿海—内陆之间的差异最大,沿海—沿海次之,内陆—内陆最小。Markov链概率转移矩阵显示,数字经济企业技术创新呈现出低水平和高水平状态相对稳定、中水平状态波动强的特征,且跨状态转移比例远低于邻近状态转移,说明数字经济企业技术创新跨越式发展难度较大。Moran指数显示,数字经济企业技术创新存在空间负相关性且保持较强的空间稳定性。α和β收敛分析显示,数字经济企业技术创新的发散态势显著,且区域间存在负向空间溢出效应。上述结论可为中国数字经济创新发展和区域协同增长政策制定提供启示。

Based on the latest standards from the National Bureau of Statistics for identifying digital economy enterprises,this study comprehensively employs various research methods to analyze the regional differences and spatiotemporal evolution characteristics of technological innovation in Chinese digital economy enterprises.According to the Dagum Gini coefficient,the overall disparity in technological innovation among digital economy enterprises shows a fluctuating upward trend.Regional disparities are the main source of the overall disparity,with a mean contribution rate of 68.31%.In terms of intra-regional differences,only the eastern coastal and middle reaches of the Yangtze River regions show a convergence trend.Regarding inter-regional differences,the largest disparity exists between coastal and inland areas,followed by disparities between coastal regions and the smallest disparities are observed between inland regions.The Markov chain probability transition matrix shows that technological innovation in digital economy enterprises exhibits characteristics where low-level and high-level states are relatively stable,while mid-level states demonstrate strong fluctuations.Moreover,the proportion of transitions between states is much lower for transitions across states than for transitions between neighboring states,indicating that the leapfrog development of technological innovation in digital economy enterprises poses significant challenges.The Moran's index indicates that technological innovation among digital economy enterprises exists spatial negative correlation and maintains strong spatial stability.Convergence analysis of“α”and“β”demonstrates a significant divergent trend in technological innovation among digital economy enterprises,and there is a negative spatial spillover effect between regions.These findings provide insights for the formulation of policies aimed at promoting innovation development in China's digital economy and regional coordinated growth.
