数字经济对黄河流域制造业全要素生产率的影响机制:创新效率的中介作用和企业家精神的调节作用OA

The improvement of total factor productivity(TFP)in the manufacturing sector is crucial for driving high-quality development and sustainable growth in the economy of the Yel-low River Basin.TFP plays a pivotal role in enhancing regional competitiveness and promoting coordinated regional development.As a new engine for economic growth,the digital economy provides fresh opportunities for improving the TFP level within the manufacturing sector of the Yellow River Basin.The 20th Central Committee's Third Plenary Session emphasized the impor-tance of promoting the deep integration of the real economy with the digital economy,strengthen-ing modern infrastructure construction,and improving the resilience of industrial and supply chains.This integration has facilitated structural transformation and upgrading in manufacturing and promoted the smartization of the manufacturing value chain by spurring innovation.More-over,the application of digital technologies has accelerated research and development processes as well as product development cycles,injecting new vitality into the continuous growth of manu-facturing TFP.Therefore,it holds significant research value and practical importance to explore how to better enhance the TFP of manufacturing in the Yellow River Basin within the context of the digital economy and examine the specific mechanisms by which the digital economy impacts manufacturing TFP. Building on existing studies,this paper utilizes data from listed manufacturing companies in the Yellow River Basin from 2011 to 2021 to examine the impact of digital economic develop-ment on manufacturing TFP in the region.Additionally,the paper explores the mediating role of innovation efficiency in manufacturing and the moderating effect of entrepreneurship and also tests the potential threshold effects in the relationship between digital economic development and manufacturing TFP.The results indicate:①The development of the digital economy signifi-cantly boosts the level of manufacturing TFP,becoming an important driver of its continuous im-provement in the Yellow River Basin.This conclusion remains valid even when considering alter-native measurement methods and addressing endogeneity concerns.②The digital economy en-hances innovation efficiency in manufacturing,which in turn promotes the growth of manufactur-ing TFP.③Entrepreneurship,as a key driver of business development,plays a positive moderat-ing role in enabling the digital economy to boost manufacturing TFP.④The impact of digital eco-nomic development on manufacturing TFP is nonlinear;it initially shows diminishing marginal returns before transitioning to increasing marginal returns.The most significant promoting effect on manufacturing TFP occurs when the level of digital economic development exceeds 0.201. Based on these findings,this paper suggests that to enhance the TFP of manufacturing in the Yellow River Basin,it is essential to accelerate the construction of new infrastructure,stimu-late entrepreneurial innovation,and continuously advance digital transformation and the develop-ment of the digital economy.
