Abstract:The current evaluation system for new research and development institutions mainly relies on non quantitative indicators, focusing on indicators such as the number of scientific research projects obtained and patent applications. It fails to fully highlight the innovative service capabilities of new research and development institutions and their ability to integrate various innovative elements. Therefore, a more scientific evaluation mechanism needs to be established. The symbiotic perspective has reference significance for solving complex, multi-level, and dynamic cross domain transactions, and is suitable for the application scenarios of innovation performance evaluation in new research and development institutions. Therefor, based on the perspective of symbiosis, we constructs a model for measuring the symbiosis degree of institutional innovation elements using the Technology - Organization - Environment framework, and selects the first three batches of new research and development institutions in Fujian Province from 2016 to 2018 as samples for calculation. The results show that symbiosis degree has a positive effect on the sustainability of institutional operation and institutional innovation ability; For new research and development institutions with public welfare attributes, located in developed regions, and serving strategic emerging industries, their symbiosis is relatively higher, and their sustained operational and innovation capabilities are stronger. It can be seen that symbiosis can be a key indicator for identifying and continuously tracking and evaluating new research and development institutions.
