Research On Radiation Effect And Countermeasures Of Shanghai Sci-Tech Innovation Center Under The Yangtze River Delta Integration Strategy

With the development of the Yangtze River Delta regional integration in 2018 rising to the national strategy,the role of Shanghai sci-tech innovation center in regional innovation and development has become increasingly important.The higher-level regional integration of the Yangtze River Delta is inseparable from the development of the Shanghai sci-tech innovation center,and it is of great significance to promote the integration of the Shanghai sci-tech innovation center to the radiating role of the Yangtze River Delta city group.Therefore,this article starts with the radiation effect of Shanghai sci-tech innovation center and studies its influence on regional innovation development.First,the radiation field model is constructed by drawing on the classic field theory,and the evolution of the space radiation effect of the Shanghai sci-tech innovation center from 2011 to 2017 is measured through the innovation element evaluation system and multidimensional distance indicators of the sci-tech innovation center.Secondly,sorting out the influence mechanism of the radiation effect of the sci-tech innovation center on the improvement of regional innovation performance,and constructing a panel regression model of the radiation effect of the sci-tech innovation center on the improvement of regional innovation performance under a multidimensional distance for empirical analysis.Finally,based on domestic and foreign experience summaries and national future development plans,building a Yangtze River Delta science and technology corridor,and using deep learning methods to explore the impact of science and technology corridor construction on the radiation effect of the Shanghai sci-tech innovation center.The countermeasures and suggestions for the construction of science and technology corridors are put forward.The results show that:(1)Since the construction of the sci-tech innovation center in Shanghai in 2014,the concentration level of innovation elements has increased significantly,and the spatial radiation effect on the Yangtze River Delta region has been significantly enhanced.Among them,the radiation effect based on technical distance is higher than the radiation effect under the dimensions of time distance and economic distance.(2)The radiation effect of Shanghai sci-tech innovation center under multi-dimensional distance has a positive effect on the improvement of regional innovation performance in the Yangtze River Delta.Among them,the radiation effect under economic distance has the best effect on regional innovation performance.There is a significant correlation between radiation effects in different distance dimensions,and based on the theory of space-time compression,it is found that the shortening of time distance helps promote the role of radiation effects in the technical and economic distance dimensions.In addition,the Shanghai sci-tech innovation center can play a radiating role in cities with different levels of innovation.Among them,the low-level cities have the most significant radiation effect.(3)Based on the analysis of the prediction results of the EMD-LSTM model,it is found that from 2020 to 2035,the Shanghai sci-tech innovation center can enhance its space radiation effect through the construction of regional science and technology corridors,thereby driving regional innovation and development.Finally,combined with the research conclusions,policy recommendations are proposed to enhance the radiation effect of the Shanghai sci-tech innovation center to promote regional integration.
