The Impact of the Digital Economy on Innovation: New Evidence from Panel Threshold Model

Abstract

The digital economy has aroused widespread concern. This paper studies the impact of the digital economy on innovation using a panel threshold model. Taking 30 provinces, municipalities, and autonomous regions in China as the research object, the time span is from 2013 to 2019. The data are from the National Bureau of Statistics of China (NBSC), China National Intellectual Property Administration (CAIPA), the China Stock Market and Accounting Research (CSMAR), and the Ministry of Industry and Information Technology (MIIT)of China. Data analysis is performed with ArcGIS 10.2 and STATA 16 software. The influence mechanism of digital economy on innovation is innovatively analyzed from the aspects of innovation elements, innovation tools, innovation subjects, and innovation environment. A digital economy development level index system is constructed using the entropy method, and the development level of China’s digital economy in time and space is analyzed. On this basis, the nonlinear impact of digital economy on innovation, i.e., the threshold effect, is innovatively studied using the panel threshold model. It is found that China’s digital economy develops rapidly, but there is a serious spatial imbalance, and there are great differences in the different dimensions of the digital economy. At the same time, the impact of digital economy on innovation has a double threshold effect with industrial structure as the threshold variable and a single threshold effect with urbanization level as the threshold variable. Specifically, the promoting effect of digital economy on innovation increases with the optimization of industrial structure or the improvement of urbanization level. This study enriches the theoretical research on the impact of digital economy on innovation, and it has important support and reference value for China’s development of digital economy and improvement of innovation capacity.

Theoretical and Methodological Aspects of Innovative-Industrial Cluster Development in the Era of Digitalization

“…It should be noted that research results are in a queue with other scientific findings. Specifically, in the paper (Xu, Li, 2022) it was also proved that digital development has a positive influence on industrial development. In turn, Zhang et al ( 2022) also pointed out that digitalization contributes to a country's industrial and economic development.…”

“…Panel data regression analysis is chosen as it is the most commonly used approach in economic growth models (Xu and Li, 2022;Zhang et al, 2022). The methodology of the Global Innovation Index considers that all pillars are assessed with a score, which varies in the range of 0-100, where a higher score illustrates the better performance of the pillar (Global Innovation Index Reports, 2022).…”

Análise prospectiva para o setor aquícola em áreas periurbanas da região metropolitana de São Paulo, Brasil

“…O período de 2000 a 2020 foi marcado pela fusão entre a biotecnologia, nanotecnologia, tecnologia da informação e comunicação (TIC), e energia limpa, impulsionando o comércio internacional e inovações digitais (Xu;Li, 2022). O avanço em genética, conhecido como "Designer genético" e a nanotecnologia empregada no setor de nutrição e diagnóstico ressaltam o papel destas tecnologias quanto à sustentabilidade e eficiência do setor (Besson et al,2020).…”
