Research on the Digital Economy's Impact on China's Economic Growth:Based on the Variations in Urbanization Levels Across China's Eastern,Central,and Western Regions and Sectoral Heterogeneity

This paper uses inter-provincial panel data from 2011 to 2017,a linear regression model,and a threshold model to conduct empirical analyses of the impact of the digital economy on China's overall economic growth and the three main sectors of industry.The paper then investigates the impact and effects the digital economy has had on the economic growth of the three main sectors of industry in China's eastern,central,and western regions.Finally,the paper investigates the most significant differences among the various regions and the threshold effects of urbanization levels on the relationship between the digital economy and economic growth.The findings indicate a significantly positive correlation between the digital economy and regional economic growth.Moreover,geographical factors notably influence this correlation.The digital economy exerts a positive effect on all sectors of industry.It may not substantially impact industrial development in regions with highly developed infrastructure.Regarding the other regions,the digital economy exhibits varying degrees of impact due to the differences in the specific indicators.The conclusion drawn by the threshold model is that the magnitude of the threshold effect correlates with geographic factors.No threshold effect was observed in the eastern region,while the threshold effect occurred in the central region when the urbanization levels for the provinces were below 0.6645.Similarly,the threshold effect was noted in the western region when the urbanization level was below 0.3931.Considering all of this,the study also offers policy recommendations that will help balance the regional development of digital economies,accelerate the digital transformation of traditional industries,enhance digital infrastructure construction,refine the formulation and implementation of data policy,and establish relevant incentive mechanisms.

Empirical Study on Effect of Industrial Structure Change on Regional Economic Growth of Beijing-Tianjin-Hebei Metropolitan Region

Based on the data of gross domestic product(GDP),industrial added value and the proportion of industrial employees from 2000 to 2008,this paper studies the effect of industrial structure change on the regional economic growth of Beijing-Tianjin-Hebei Metropolitan Region in China using the shift-share method.The results show that:1) In the 21st century,the industrial output of three industries,namely,primary,secondary,and tertiary,and the GDP grew rapidly in the study period.The tertiary industry grew the fastest;it had the largest contribution to the GDP and mean-while had become the most competitive industry in the metropolitan region.2) The development of cities within the region was not balanced.Firstly,compared with Tianjin,Beijing,as one of the two core cities,was more rational in the industrial structure.Secondly,the surrounding eight cities,which are Shijiazhuang,Qinhuangdao,Tangshan,Langfang,Baoding,Cangzhou,Zhangjiakou,and Chengde,were all uncompetitive than the two core cities.3) There was a great industrial gradient in the region(especially between the two core cities and the cities of Tangshan,Baoding,Zhangjia-kou,Chengde,Cangzhou,and Langfang).As a result,it is foreseeable that the industry transfer in the Bei-jing-Tianjin-Hebei Metropolitan Region will be one of the trends in regional development,and the industry transfer is inevitably to promote the regional integration.

A Study on Investment Structure of Fixed Assets and Regional Economic Growth

Nowadays,it has been in the period of rapidly developing China’s economy.Since the financial crisis in 2008,China has paid more and more attention to investing in fixed assets,and the growth rate of investing in fixed asset is also rising.However,when promoting regional economic growth,if we only pay attention to the total amount of fixed asset investment,there will inevitably exist some blindness and lack of sustainability.Therefore,the study between the investment structure of fixed assets and regional economic growth is quite important.China has a vast territory and many regions.The investment structure of fixed assets in different regions is also different,so the influence on economic growth is also different.This paper analyzes the investment structure of fixed assets and regional economic growth,and help realize the rapid growth of regional economy by recognizing the current situation of China's investment structure of fixed assets.

Spatio-temporal characteristics of regional sustainable economic growth drivers of China

Intellectual capital(IC)has become a universal performance indicator for the socioeconomic development of countries and regions.Based on a review ofnational intellectualcapital(NIC)and regional intellectualcapital(RIC)evaluation literature,we used the regional intellectualcapitalindicator(RICI)as a model for China’s RIC evaluation to indirectly understand China’s potential economic growth drivers.Specifically,we collected statisticaldata of31 provinces(including municipalities and autonomous regions)in China from 2004 to 2016to measure RICI and analyze its dynamic characteristics from temporal and spatial perspectives.In this paper,Delphi analysis was used to construct RICI model,and cluster analysisand exploratory spatial data analysis were used to analyze the temporal and spatial characteristics of RICI in China.The results showedthat RICI,which represents China’s overall economic growth drivers,increases annuallyand is consistent with economic developmentlevelduring the study period.Regarding the geo-spatial space,RICI follows the trend of“high in the east and low in the west”,gradually decreasing from eastern to western China.ForRIC structure,the shape of the radar chart of IC structure located in the eastern coastal areas is usually biased towards strong external relational capital,while that in western China is generally biased towards structural capital.For spatial correlation,China’s RICI has dependence on geographical adjacent space and economic space.Our research can provide policy suggestions for the sustainable development of regional economy from an IC perspective.

China’s Potential Economic Growths during 2015-2025 under Different Scenarios~

China has entered a crucial period of further growth and restructuring that will last until 2025. Based on a review of the major factors affecting China＇s potential economic growth, this paper has created an integrated economic system model consisting of system dynamics, econometrics, and input-output for the forecast of China＇s economic size and structure by 2025. Analysis shows that prior to 2025, China will be able to maintain a potential annual economic growth rate of 5.7%-7.2%. Faced with an international environment of a possible slowdown of advanced economies and diminishing demographic dividends, China needs to further expedite its urbanization process, enhance R＆D and education spending, increase total factor productivity （TFP）, vigorously develop the tertiary sector, and expand consumption in order to achieve the optimistically estimated growth of 6.6%-7.4% during the period of 2015-2025. Economic growth should be accompanied by the upgrade of industry structure and improvement of investment and consumption structures.
