摘　　要：促进实体经济和数字经济深度融合是党中央立足全局、面向中国式现代化作出的重大战略抉择。本文利用2003—2015年中国工业企业数据和机器学习模型,通过测算工业行业和核心数字产业之间的技术关联度,构造中国数字产品空间,并基于产业数字邻近性和比较优势耦合协调的发展逻辑,探究如何实现实体经济和数字经济深度融合。研究发现:中国经济的实数融合程度稳步提升,在研究期内提升63.73%,但区域间数字鸿沟问题突出,区域间实数融合差异增长51.16%。数字产品空间的耦合协调度具有区域根植性,且对数字经济发展具有持续影响,耦合协调度每增长1个标准差,省级和地市层面的数字经济水平分别增长36.95%和9.62%。基于技术关联和比较优势耦合协调原则,中国应重点推进实数融合发展的产业是金属制品业、专用设备制造业、化学制品和非金属矿物制品业。通过分析不同地区的行业耦合协调度,本文提出因地制宜的数字化转型优先顺序。Promoting the deep integration of the real and digital economy is a major strategic decision made by the CPC Central Committee facing Chinese modernization.Promoting the integration of the real and digital economy has become an important driver for enabling the construction of a modern industrial system and high-quality economic development.Driving the construction of a modern industrial system with digital transformation is a major theoretical and practical proposition for building a great modern socialist country.The digital economy is a new economic form driven by technology.Therefore,when promoting the digital transformation of industries,the technological relatedness between industrial sectors and digital industries should be emphasized.Meanwhile,the economic attributes of the digital economy call for a focus on the economic conditions of regional resource endowments and industrial foundations.Based on the microdata of Chinese industrial enterprises from 2003 to 2015,this paper uses machine learning models to construct China's digital product space by measuring the technical relatedness between industrial sectors and core digital industries,and explores how to achieve the deep integration of the real and digital economy in China based on the logic of coupling coordination of digital proximity and comparative advantage.The research results are as follows.China's real and digital integration has steadily improved,increasing by 63.73% during the research period,but the problem of the digital divide between regions has always been prominent,and the difference in real and digital integration between regions has increased by 51.16%.The coupling coordination degree of digital product space is rooted and has a lasting impact on the development of the digital economy.For every standard deviation increase in coupling coordination degree,the digital economy at the provincial and city levels can increase by 36.95% and 9.62%,respectively.According to the principle of coupling coordination development of technical related
