我国数字经济与体育产业耦合协同发展的实证研究——基于耦合协调度模型与灰色关联分析法

An Empirical Study on Coupling and Coordinated Development of Digital Economy and Sport Industry in China Based on Coupling Coordination Degree Model and Grey Correlation Analysis

数字经济是新时代体育产业高质量发展的新动能和新引擎。数字经济通过规模经济、范围经济、技术创新效应促进体育产业发展,体育产业反向推动数字经济要素多样化和精准化、推动数字基础设施建设加速。首先,运用2015—2019年我国数字经济和体育产业数据,采用熵值法,构建数字经济与体育产业的评价指标体系和耦合协度模型,系统考察数字经济与体育产业的双向作用及动态关系。研究发现,2015—2019年体育产业和数字经济的综合发展水平呈现上升趋势且发展速度较快,两者的耦合度持续高度相关、耦合协调度由濒临失调逐渐发展为优质协调,呈现出越来越强的协同促进关系。其次,采用灰色关联分析法,检验了影响两者耦合协同发展水平变化的因素。结果表明,产业数字化规模、数字经济规模、体育产业规模、科技创新水平、经济发展水平、金融支持、市场需求、企业竞争、体育科技财政支出均与耦合协同发展水平存在关联性。最后,提出提升体育产业数字化水平以加深数字经济与体育产业耦合、发挥财政金融要素引擎作用以助力数字经济与体育产业融合升级、强化体育市场主体功能以筑牢数字经济与体育产业耦合发展根基等促进建议。

Digital economy is a new driving force for the high-quality development of sports industry in the new era.Digital economy promotes the development of sports industry through scale economy,scope economy and technological innovation effect,while sports industry promotes the diversification and precision of digital economy elements and the acceleration of digital infrastructure construction in reverse.Based on the data of China's digital economy and sports industry from 2015 to 2019 and using entropy method,this paper constructs the evaluation index system and coupling coordination degree model of digital economy and sports industry to systematically investigate the two-way effect and dynamic relationship between digital economy and sports industry.The study finds that the comprehensive development level of sports industry and digital economy showed an upward trend and a fast development speed from 2015 to 2019,and the coupling degree of the two systems continued to be highly correlated.Meanwhile,the coupling coordination degree of the two systems gradually developed from the verge of disorder at the beginning to high-quality coordination,showing an increasingly strong synergistic promotion relationship.Furthermore,the factors influencing the level of coupling and collaborative development are tested by using grey correlation analysis method.The results show that the scale of industry digitalization,the scale of digital economy,the scale of sports industry,the level of scientific and technological innovation,the level of economic development,financial support,market demand,enterprise competition,sports science and technology fiscal expenditure are all correlated with the level of coupling and collaborative development.Finally,the paper put forward the following proposal:Improving the digitalization level of sports industry to deepen the coupling between digital economy and sports industry,giving play to the role of financial elements as an engine to help the integration and upgrading of digital economy and sports industry,and strengthening the main function of sports market to build a solid foundation for the coupling development of digital economy and sports industry.
