The Impact of Digital Economy on Total Factor Productivity of China’s Service Industry

As a kind of integrated economy,digital economy has an important impact on the economic growth and production and lifestyle of multiple countries and regions,and plays a significant role in promoting the reconstruction of the international economic pattern.As an important industry of China’s national economy,the service industry is crucial to China’s economic growth.This paper measures the development level of digital economy in provinces and cities through constructing digital economy index system,uses super efficiency SBM-Malmquist model to measure total factor productivity of service industry,and tests the influence effect of digital economy on total factor productivity of Chinese service industry.Finally,the optimization path of digital economy on China’s service industry is proposed.

Protection of Innovative Achievements,Spatial Spillover,and Internal Structural Upgrading of the Productive Service Industry-Empirical Evidence from 28 Provinces in China

This study measured the level of innovation achievement protection and the degree of internal structural upgrading of the productive service industry in 28 provinces of China from 2000 to 2022.Exploratory spatial analysis methods were used to test the spatial correlation between the two variables,and the spatial impact of innovation achievement protection on the optimization of the internal structure of the productive service industry was examined at the national and sectoral levels.The results showed three main aspects of this system.(1)The agglomeration level of innovation achievement protection and internal structure optimization of the productive service industry between regions in China continued to increase during the sample period,and there was a clear similarity and synchronicity in the spatial evolution of the two variables.(2)The overall improvement in the protection level of innovative achievements is conducive to promoting the internal structural upgrading of China’s productive service industry.However,there are significant differences in the degree to which the protection of innovative achievements affects the internal structural upgrading of the productive service industry in the four major regions of the East,Central,Northeast,and West.The protection of innovative achievements in the East and Central regions significantly promotes the internal structural optimization of the productive service industry,while this effect is not significant in the western and northeastern regions.(3)The results of the robustness test indicate that the impact of internal structural upgrading of the productive service industry in the previous year on the level of innovation achievement protection is not significant.The interference from abnormal values of the internal structural upgrading of the productive service industry in various regions and the influence of municipalities directly under the central government on the regression results are not significant.After replacing the main variable,the coefficient of the innovation achievement protection level remained significantly positive.The conclusions of this study supplement and improve the theory of innovation achievement protection and industrial transformation and upgrading,providing decision-making support for improving the level of innovation achievement protection and promoting the internal structural upgrading of the productive service industries in China.

Supply-Side Structural Reform in the Service Industry and Escaping the Middle Income Trap

The internal consumption and production structure of the service industry that now dominates the Chinese economy needs to be optimized.Introducing supply-side structural reform to improve the in-depth integration of advanced manufacturing and the modern service industry and promoting a strong domestic market is the key to escaping the middle income trap.We use 1950-2010 data from 45 non-oil-exporting economies representing the structural evolution of the service industry worldwide to compare Asian economies that have passed through the middle income trap with Latin American counterparts that remain stuck in the trap,and thence proceed to construct a matched model that covers the consumption and production service industries and their supply of human capital,with the aim of identifying the formative mechanisms and conditions for escaping the middle income trap through upgrading the structure of the service industry.Substantially developing the production service sector,raising the supply of public services so as to cultivate the quantity and quality of human capital,and matching senior-level human capital with knowledge-intensive serviceindustries will propel the upgrading and transformation of China’s economic structure toward high-quality development.
