What the literature leaves open

  • In summary, our future research will focus on expanding the sample range, delving into policy implementation mechanisms, enhancing the comprehension of public participation in policy-making, and further exploring the moderating effect of economic policy uncertainty. Firstly, this paper predominantly focuses on developing regions, leaving a gap in understanding the situation in developed countries. Additionally, while this paper has proposed that public environmental concern mediates and economic policy uncertainty moderates the relationship between government environmental attention and innovation in the new energy industry, there research on how public environmental concern and economic policy uncertainty influences policy formulation and implementation by local governments, and how policies, in turn, affect public concern is still sparse.

  • The study identifies the challenge of limited urban participation in central and western China. The study highlights the challenge of insufficient collaborations in basic research among academic institutions. The study notes the challenge of administrative barriers reducing participation from cities in central and western regions.

    Innovation networks in the advanced medical equipment industry: supporting regional digital health systems from a local–national perspective · 2025 · DOI

  • The industry relies heavily on imports, with over 80% of advanced medical equipment being imported. There is a lack of collaborative innovation within the industry, particularly among cities in central and western China. The study identifies a need for targeted policy design to strengthen collaboration in the advanced medical equipment industry.
