Research On The Impact Of R&D Investment On The High-quality Development Of Regional Economy

Since the reform and opening up,our country’s economy has developed rapidly and our economy has grown rapidly.However,with the gradual loss of the demographic bonus advantage,environmental pollution,and overexploitation of resources,our country’s traditional mode of economic growth does not meet the current demands of economic development,and more attention is being paid to maintaining the pace of economic growth while aiming for high-quality economic development.As an important component of scientific and technological innovation,investment in research and development plays an important role in the economic development of our country.In the context of the economic transformation taking place in our country,it is of great theoretical and practical importance to study the impact of R&D investments on the quality development of local economies.First,it classifies and summarizes relevant domestic and international studies and analyzes the relationship between R&D investment and quality economic development.Second,based on data from 30 provinces and cities(excluding Hong Kong,Macao,Taiwan,and Tibet)for the period 2013-2020,we will explain and analyze the current status of R&D investment in our country in terms of funds and personnel,and build an R&D investment indicator system.At the same time,based on the significance of quality economic development,we will construct a quality economic development indicator system in terms of innovative production,cooperative development,green life,openness,and sharing of results,and determine the weights of the indicators using the AHP hierarchical analysis method to create comprehensive indicators for R&D investment and quality economic development,respectively.We then conduct a comparative analysis of the level of R&D investment and the level of quality economic development in Japan over time and space.Next,using Stata software,we calculate global Moran indicators of R&D investment and quality of economic development,create local Moran scatter plots,and investigate their spatial clustering characteristics.Finally,based on the weighted economic distance matrix,we construct the most appropriate spatial Doberman model and empirically examine the impact of R&D investment on local economic development.The results show that:(1)the scale of R&D investment in China expanded rapidly in 2013-2020,but there are differences among provinces and cities,and the level of R&D investment is relatively low in China’s central and western regions.(2)The overall assessment of quality economic development in all of China’s provinces and cities shows a steady upward trend,but with large spatial effects across regions.Overall,there are significant differences in the index of quality economic development for all provincial cities in China,as well as significant spatial differences and aggregate phenomena.(3)According to the economic distance weighted matrix,the level of quality economic development of all Chinese provinces and cities shows a significant positive spatial correlation,meaning that provinces and cities with higher levels of development can stimulate the development of neighboring provinces and cities.(4)The regression results of the SDM model with time fixed effects show that for every increase in the level of R&D investment(Rd),the level of quality economic development of regions and cities increases by 0.125 units,indicating that R&D investment has a significant positive impact on promoting quality economic development of regions and cities.Labor force(L)does not play a significant role in promoting quality economic development,indicating that labor force(L)does not play a significant role in promoting regional and urban quality economic development in the short run.Capital stock(K)plays a significant role in promoting quality economic development in provinces and cities as well as in neighboring provinces and cities,and has a significant impact on the quality of economic development.Finally,based on these theoretical and empirical findings,this paper provides policy recommendations to promote quality regional economic development in terms of R&D investment.
