Abstract:Based on three-participant theory, this paper analyzes the problems in government constructing innovation environment, scientific research institutions providing technologies and talents, and enterprises exploiting the market in Huairou Science City. Including: the management mechanism is not smooth, the life service supporting is insufficient, scientific research institutions are insufficient, the science and technology resource sharing mechanism is imperfect, the industrial structure support is insufficient, and the enterprise innovation ability is weak. In order to promote the construction of Huairou Science City as a comprehensive national science center and lead Beijing's transformation and upgrading of high-quality development, some suggestions are provided, government should be service-oriented and strengthen the construction of better policy and living environment; scientific research institutions should proactively settle down in Huairou, and promote the opening and sharing strategy by starting with the large scientific devices; and enterprises should optimize industrial structures, attract and incubate startup firms, and build innovation platform to connect more innovation resources. The research results can provide support for the formulation of Beijing's "14th five year plan", and also provide basis for relevant policy making.
