Abstract: The competitive advantage of platform ecosystem is the ability of value creation between platform organizations and complementary organizations. The existing literature mostly studies platform enterprises, and divides the types of value creation into two categories: Service-Dominant(S-D) logic and Customer-Dominant(C-D) logic. However, different value creation activities carried out by varies types of platforms often have significant heterogeneity. NRDI is a platform organization integrating R&D, technology transformation, business incubation and R&D services constructed by the government, industry and university with a "triple helix" structure. NRDIs can effectively use and integrate the resources of the platform sponsors, and frequently interact with external organizations as the core of value exchange in the platform ecosystem. Compared with traditional R&D institutions, New R&D Institutions (NRDIs) have platform attributes such as resource integration, function integration and network amplification effect, especially in the incubation of science and technology enterprises. The complexity of value creation caused by the heterogeneity of the characteristics and platform types of NRDIs requires further investigation. On this basis, our research attempts to construct a theoretical framework about the impact of platform organizational attributes on the value creation of NRDIs from the perspective of platform ecosystem. In the conceptual framework, we analyze factors affecting NRDIs’ value creation, including the internal structure of platform types and functions, as well as external interaction and governance mechanisms. Using the survey data of 1458 NRDIs in China conducted by the Ministry of science and technology in April 2020, we apply empirical analysis to identify which NRDIs have comparative advantages in value creation. The value creation of NRDIs is measured by the number of enterprises incubated by NRDIs. There are four independent variables: platform type, platform function, platform openness and governance mechanism. Among them, platform type is set as a virtual variable, followed by public institutions, private non-enterprise and enterprise, while the other internal variable, platform function, includes three variables, scientific research, technological innovation and R&D services. The three variables reflecting the openness of the platform are: the establishment of organizational innovation alliance, the establishment of innovation platform and the establishment of service network, and each variable has corresponding sub-variables. The variables representing the openness of platform are: organizational innovation alliance, innovation platform and the service network. The variables representing the governance mechanism are actual (board) governance and no actual (board) governance, which are also dummy variables. Results show that platform type of public institutions, platform function of integrating scientific research, technological innovation and R&D service, platform openness of innovation alliance, high-level innovation platform and enterprise service network, governance mechanism of the implementation of board governance according to market-oriented means are dominant. Based on the above empirical conclusions, we also put forward policy suggestions, such as encouraging NRDIs to actively undertake R&D projects at national and local levels, to actively participate in the formulation of industry standards, to establish R&D service networks with small and medium-sized enterprises, and building a high-level innovation platform. The conclusions have guiding significance for formulating targeted policies for the development of NRDIs and have a certain reference for promoting the high-quality development of regional economy.
