摘要
Industry interaction is becoming an important approach to promoting highquality economic development.In this paper,the multi-sector general equilibrium model is developed to clarify the theoretical mechanism among industry interaction,structure transformation,and high-quality economic development;the empirical tests are carried out based on the provincial panel data from 2000 to 2017;and the empowerment paths for digital technologies are explored to drive high-quality economic development.The findings are as follows.(1)The industry interaction can promote high-qualityy economic development in China on the whole,but it shows a significant imbalance and a healthy two-way promotion mode have not been formed.(2)The impact of industry interaction on high-quality economic development is significantly heterogeneous at the sector and regional levels.(3)The current unhealthy industry interaction may widen the productivity gap between manufacturing and service sectors,and transform China's economic into service-oriented structure,thus leading the economic development to a vicious circle of“low efficiency to low-end servitization and further to lower efficiency”and hindering the sustainability of high-quality economic development:.(4)Digitaltlechnologies can break the development dilemma and achieve high-quality economic development by alleviating structural contradictions,boosting healthy industry interaction,and narrowing the productivity gap among sectors.The conclusions provide empirical evidence for the government to promote the integration of advanced manufacturing and modern service sectors and achieve highquality economic development.
