System Dynamics Based Approach To The Sustainablility Analysis Of University Owned Sci-tech Industries

With its continuous expansion of scale, the sustainability of university-owned sci-tech industries is paid more and more attention. On the one hand, there are many management and governance challenges in university-owned sci-tech industries because of its particularity, that is the dependence on universities. On the other hand, the sustainability of university-owned sci-tech industries is different with general business and it’s uniqueness needs to be studied theoretically. Therefore, research on the sustainability of university-owned sci-tech industries with its basis on the present situation of university-owned sci-tech industries in China has important theoetical significance and practical value.On the basis of the above understanding, the thesis attempts to explore the issue concerned with the sustainability of university-owned sci-tech industries, employing the combined method of specifications and demonstration. First of all, the driving factors affecting the sustainability of university-owned sci-tech industries are verified based on the method of combination of large samples and structural equation model. Secondly, system dynamics model is built and tested relying on the driving factors and their corresponding variables. Finally, integrating with the systems dynamics model, simulation experiment and optimization concerning policies for the sustainability of university-owned sci-tech industries are conducted.Main work and conclusions are made in this thesis:Ⅰ. To build system of university-owned sci-tech industries. This system is composed of factors(including University support, Government support and Social support), effects(the sustainability of university owned industries and the transformation of sci-tech achievements of universities), external environment(comprising of support from government, finance and tax preferential policy, situation of macroeconomic, recogniton and acceptence of society towards the industry) and ralations, forming a complex and dynamic organic system.Ⅱ.To put forward a coordination model of the sustainability of university-owned sci-tech industries, and test it with empirical methods. According to the questionnaire, the thesis has verified the relationship between the sustainable development and government support, university support, cooperation with supply chains, intensity of competition, technical collaboration with outside scientific institutions, absorptive ability, knowledge transmission capacity and ability of resource integration, employing correlation analysis, multiple regression analysis, structural equation model. Correspondingly, the conclusion is made through empirical analyses in this article. Firstly, the support from government, university and society is the key external factor in promoting sustainable development of university-owned sci-tech industries. Secondly, enterprise ability (absorptive ability, knowledge transmission capacity and resource integration abilitiy) is key internal factor in promoting the sustainability of the industriy. Thirdly, the Government, university and social support affect the sustainability of university-owned sci-tech industries directly and indirectly.Ⅲ. To build the system dynamics model of the sustainability of university-owned sci-tech industries, and test it with real cases. In the process of building system dynamics model, the thesis has built four modules, namely sub module of the sustainable development of university-owned sci-tech industries; sub module of university support; sub module of the government support; sub module of social support. Based on the sub modules, the article has constructed causal loop diagram and system flowchart of the system dynamics, and then established level variable, flow rate variable, auxiliary variable, contents and their relevant mathematical formula. On the basis of the system dynamics model, the thesis has tested the model, integrating with actual operating data of a university-owned sci-tech enterprise (A company) established by the computer school of a famous university in China.Ⅳ. To test some policies of university-owned sci-tech industries combining with system dynamics model, and put forword targeted suggestions concerned with policy optimization. Through the changes of parameter in system dynamic model, it can come to the experiment and optimization of policies of university-owned sci-tech industry and the conclusion demonstrated that support policy of universities play an active role for sustainable development of the industry. In the long term, Government support can effectively improve the earnings growth rate of the industry, but has less impact on sales growth rate. However, to increase social support can effectively promote practical sustainable development capacity of university-owned sci-tech industry.Ⅴ. To put forward solutions and suggestions to promote sustainable development of university-owned sci-tech industries, and discuss the future research in this field. Here are the four proposals:(1) Considering that the supports of universities, government and society can be regarded as the key factor in promoting sustainable development of university-owned sci-tech industry, we should coordinate them to play their roles.(2) in view of the fact that university technical/intelligence supports have become the important factors of sustainable development of the industry, we should strengthen the depth and breadth of the integration among research, study and industry.(3) Because the impact of government support is active but not comprehensive, we should innovate support mode, and improve market competitiveness of the industry.(4) Considering social support plays a significant role in sustainable development of university-owned sci-tech industry, we should take its advantages to propel the level of socialization of the industry. Simultaneously, this thesis points out that the future research on the support from government, university and society for the development of university-owned sci-tech industries should be centered on the efficiency and effectiveness of knowledge innovation and transmission of university.
