Angel investment is an effective investment and financing way to combine the innovative elements such as capital,talent,technology,management with the start-up enterprise.Meanwhile,it is an important capital strength to promote public entrepreneurship and innovation.Angel investment plays a more important role in easing the financing difficulties of small and medium-sized enterprises in the early and promoting macro-economic development.Hubei province is a province of science and education,but the combination of science and technology with economy is not enough,it is a serious phenomenon that science-technology and economy are not integrated.To speed up the development of angel investment,encourage and lead private capital to actively participate in innovative start-ups investment,which is a valid approach to cultivate strong high-tech enterprise team,but also an important measure to enhance the Hubei province science and technology entrepreneurship development level,promote close integration of technology and economy,speed up achieving the development of innovation driven.In this thesis,on the basis of the current situation and problem analysis of the angel investment development in Hubei province,it uses internal and external successful experiences for reference,according to the path dependence theory and the path creation theory,it analyzes the path dependence and the path creation of the angel investment development in Hubei province.Besides,it uses the Bayesian network modeling and simulation to optimize the angel investment development of Hubei,and carries out the top-level design which is about Hubei province promoting the angel investment development,and puts forward some countermeasures and suggestions such as the system and mechanism innovation on Hubei province promoting the angel investment development.This thesis is divided into seven chapters:The first chapter is introduction.It mainly expounds the research purpose and significance,the related articles;reviews at home and abroad,and the research contents and research methods of this thesis,it points out the logical train through the technology roadmap.At present,although there are some researches on the angel investment development path in the domestic and overseas,still in the exploring stage in general.The researches are not systematic enough,presenting a "loose" for debris morphology,and lacking the support of theoretical foundation on the path of angel investment development.Furthermore,the research aiming to Chinese situation is less,especially combining the reality of Hubei province.The second chapter is the basic theory of angel investment.It primarily concludes path dependence theory,path creation theory and Bayesian network principle and method,which will provide basis for the analysis of Hubei angel investment path and the optimization.The third chapter analyzes the current situation and problems of Hubei angel investment development.Its investment in small scale,lack of professionals and teams,unreasonable investment structure and lack of star angel investors result from not catching-up mechanism construction,not well-formed platform construction,weak financial system and immature cognitive environment by comparing the actuality domestic and overseas.The fourth chapter is the analysis about angel investment path in Hubei province.As the development of angel investment can not be separated from the guidance of public policy,this thesis combines angel investment with public policy,and sums up four development paths in angel investment: the government guides the development of angel investment,investment and financing platform promote the development of angel investment,production and research drive the development of angel investment,the market leads the development of angel investment.In the last two sections of this chapter,based on the path dependence theory,it analyzes the positive locking effect and the negative locking effect in the four path modes respectively.The fifth chapter is the analysis about the optimization of angel investment path in Hubei province.By improving the cultural system,economic system,legal system,administrative system and fiscal and taxation system,it can overcome the negative locking effect,such as cognition,environment,policy and structure.The last two sections of this chapter are the modeling parts,it summarizes the breakthrough factors of development path about angel investment,and uses situational research,and combine with field research to design the Bayesian network topology about the development path of angel investment in Hubei province.Through computer simulation,it gets the optimized paths and key influencing factors of angel investment in Hubei province.The sixth chapter is the countermeasures and suggestions for the development of angel investment in Hubei.The thesis puts forward some suggestions on the top-level design of angel investment in Hubei province and the innovation of system and mechanism.At the top-level design,it puts forward the overall framework,the development of angel investment in Hubei Province,the main targets and key tasks;In terms of institutional innovation,it emphasizes the market dominant position of angel investors and angel investment institutions,deepen reform of investment and financing system,optimizing the legal supervision organization;In the mechanism of innovation,it is necessary to improve the exit mechanism,establish investment service-docking mechanism,build “angel--industry,education,and research” collaborative mechanism.The seventh chapter is the summary and outlook.It summarizes the results and shortcomings of this thesis.The three main innovations of this thesis are as follows:(1)It digs out the "four positive and four negative" lock-in form in Hubei province the development of angel investment,which points out the direction of optimization-path on angel investment development of Hubei province.(2)It establishes a model based on the Bias network in the path optimization of angel investment in Hubei province,which provides quantitative research methods on innovation of the optimal path of angel investment.(3)It puts forward the top-level design of angel investment development in Hubei province,which provides a new idea for the Hubei angel investment development planning. |
