Abstract: From the perspective of enterprises and universities/institutions respectively， this paper empirically studied the status of Chinas industry-university-institute cooperation and the factors impacting the cooperation effect among Chinas technology innovation alliances. Based on a questionnaire of 100 universities/institutions and 100 enterprises， factor analysis， correlation analysis and regression analysis were given to explore the factors for successful cooperation and the effects of government support on cooperation. The results showed that industry-university-institute cooperation in the form of alliance has significant impact on the cooperation effect but universities/institutions pay less attention to it. As to the factors for successful cooperation， enterprises attach equal importance to capability and mechanism while universities/institutions give priority to capability. Thus， the government should increase policy support for enterprises and guiding support for universities/institutions.

Key words: technology innovation alliance, industry-university-institute cooperation, government support, enterprise, university, institution
