Research on the Impact of Digital Innovation Ecosystem Niche Suitability for High-Quality Economic Development

This paper selects the relevant data of 30 provinces and cities in China from 2010 to 2022 as samples. By constructing a digital innovation ecosystem (DIES) niche suitability model, the overall and regional differences in China’s DIES niche suitability were analyzed. On this basis, static and dynamic panel data models were established to empirically analyze the influence of DIES niche suitability on high-quality economic development. The results showed that (1) the overall level of niche suitability for China’s digital innovation ecosystem is relatively stable, with unbalanced development among regions, but plentiful space for development. (2) The DIES niche suitability plays a significant role in promoting high-quality economic development. Regions with a high degree of DIES niche suitability have more active innovation activities and a higher original accumulation of innovation. (3) The positive effect of DIES niche suitability for high-quality economic development is sustainable. The improvement in regional economic development quality needs to gradually emerge with the continuous improvement in and optimization of the DIES.
