数字经济政策与制造业智能化专利研发
Digital Economy Policies and Intelligent Manufacturing Patent R&D:A Quasi-Natural Experiment
摘要
Abstract
The National Digital Economy Innovation and Development Pilot Zones are dedicated to promoting the application of advanced digital technologies and facilitating the deep integration of the digital economy with the real economy.To accelerate the intelligent transformation of the manufacturing industry and enhance industrial competitiveness,this study takes the first batch of pilot zones as the research subjects and uses the panel data of 30 provincial-level regions across the country from 2016 to 2023.The difference-in-differences method is employed to examine the impact of the pilot zones on the intelligent patent research and development in the manufacturing industry.The research results show that the policies of the pilot zones significantly promote the intelligent patent research and development in the manufacturing industry of the pilot regions,and this conclusion has passed a series of robustness tests.The heterogeneity analysis reveals that the policies of the pilot zones have a significant promoting effect on the intelligent patent research and development in the manufacturing industry in the western regions,but no statistically significant impact is observed in the eastern regions.In addition,the policies of the pilot zones have significantly increased the proportion of intelligent manufacturing patents in regions with lower economic development levels,higher environmental regulation intensities,and greater digital economy policy efforts.The mechanism test indicates that the policies of the pilot zones have improved the research and development level of intelligent manufacturing patents in the pilot regions through the institutional integration of the national unified large market,the enhanced accessibility of digital inclusive finance resources,and the optimization of the human capital structure,thereby accelerating the intelligent transformation of the manufacturing industry.Therefore,it is necessary to strengthen the design of regional differentiated policies,deepen the research on mechanism coordination,and expand the perspective of"intelligent-green"coordinated transformation to enhance the intelligent level of the manufacturing industry.关键词
