Abstract:     In this paper, through the case study method, using the triple helix space theory, the analysis framework of the interaction logic among university, industry and government is constructed. Taking the development of domestic lithography equipment industry driven by the national 02 major project and the integrated circuit industry policy as an example, this paper discusses the positive significance of the lithography industry practice on the establishment of the external development environment of application-oriented universities, and demonstrates the necessity and mechanism of establishing external triple helix environment for application-oriented universities in China. The core mission of application-oriented universities is to promote the development of regional economy and society, and provide human and intellectual resources guided by external demand. Under the background of knowledge society and innovation development, application-oriented universities can develop more effectively in the triple helix environment of government-university-industry.Taking the development of domestic lithography industry supported by industrial policies as an example, this paper takes the triple helix theory as the analytical framework to explain that the development of domestic lithography industry is the objective evolution result of the implementation of national industrial policy. The central and local governments integrate domestic academic institutions and existing industrial resources through industrial funds and policy preferences, and appropriately support the development of emerging industries related to microelectronic equipment according to the regional economic characteristics and industrial foundation, forming a triple helix interactive industrial alliance with government industry university as the basic element. The innovation ecosystem of lithography industry is organized by the government, participated by universities and research institutions, and composed of 02 special enterprises, suppliers and photolithography customers. The government is the catalyst to promote the triple helix cooperation. The formation and development of the knowledge space, consensus space and innovation space of the lithography industry development have the particularity of China′s scientific and technological innovation practice. Under the guidance of national policies, supported by major special projects and industrial funds, universities and research institutions research and tackle key technologies of lithography, and enterprises support, coordinate and organize the development and industrialization of lithography machines. From its establishment to development, the lithography industry benefits from the operation of this triple helix model.The triple helix practice case of domestic lithography industry development has certain enlightenment on the external environment of university application-oriented development. The conclusion is that the development practice of lithography industry provides a new opportunity for the cooperation between universities and enterprises, and creates a new platform and mechanism for the cultivation of new talents. The industrial support policies implemented by the state provide opportunities for some universities to improve their applicability. Universities actively integrate into the regional economic innovation and development. The triple helix system of government university industry provides a positive interactive external environment for the sustainable development of application-oriented universities. Only by integrating into the regional innovation and development and assuming specific roles and responsibilities, universities are more likely to actively and effectively serve the social and economic development, cultivate the talents they need, and provide and transform the knowledge and technology they need.
