中国数字基础设施与绿色技术创新的协同关系及其影响因素OACHSSCD

The development of synergy between digital infrastructure and green technology innovation holds great significance for China's high-quality development.Studying the factors that influence the synergy between digital infrastructure and green technology innovation provides theoretical insights for achieving this synergy.Using panel data from 31 provinces in China from 2011 to 2021 as the research object,a dispersion coefficient coordination model is employed to evaluate the synergy between digital infrastructure and green technology innovation.Additionally,a Tobit model is constructed to analyze the factors that influence this synergy.The findings are summarized as follows:①Nationally,the synergy between digital infrastructure and green technology innovation is exhibiting a stable upward trend,indicating a mutually beneficial relationship where each promotes the other.②At the regional and provincial levels,the overall degree of synergy is observed to be increasing.However,there are noticeable variations in the degree of synergy among different regions and provinces.③Regarding influencing factors,per capita GDP,which represents the level of economic development,emerges as the most significant factor in driving the synergistic development between digital infrastructure and green technology innovation.On the other hand,the concentration of PM2.5,reflecting environmental pollution,has a negative influence on the synergistic relationship.
