| In the development of knowledge economy and information technology,the proportion of external innovation knowledge in industry innovation has already been more than half,and there is a trend of increasing year by year.Because of the weakness of the new start-ups in China,they will be constrained by the lack of resources and technology;and the continuous evolution of the specialized division of labor,which makes the market division of labor gradually refined.An enterprise only relies on its own internal knowledge is far from meeting the requirements of disruptive innovation on knowledge.However,external knowledge search can greatly improve this aspect of the problem,and its impact on disruptive innovation has become the focus of academic issues.At present,the existing research focuses on the positive effect of knowledge search on innovation performance and breakthrough innovation,but the research on the impact of disruptive innovation has not been explored.At the same time,in the case of reading and combing a large number of literature,and understanding the current situation of the environment faced by enterprises,this paper introduces the variables of environmental dynamics,and considers the regulatory role of environmental dynamics for disruptive innovation of new enterprises.Based on the existing literature research,this paper divides external knowledge search into external knowledge search width and external knowledge search depth,divides disruptive innovation into new market disruptive innovation and low-end market disruptive innovation,divides the concept of new enterprises from the length of business years,and combined with the analysis of market and technical knowledge in knowledge search,this paper analyzes environmental dynamics from two dimensions of market dynamics and technical dynamics.In view of the above-mentioned variable relations,take the newly established enterprises as the research object,firstly,based on the knowledge-based view and medici effect,this paper puts forward the research hypothesis and research model framework.Then,according to the results of the pre survey,the existing mature scale is used for reference,and the qualified questionnaires are continuously collected and selected.After that,with the help of SPSS and AMOS statistical analysis application software,the collected data are processed and analyzed,and the empirical results are obtained.Finally,the theoretical inference hypothesis is compared with the empirical research conclusion,so as to get the research hypothesis and management enlightenment of this paper.From the perspective of knowledge search,through the empirical study of 230 new start-ups,this paper confirms the impact of the two dimensions of external knowledge search on the two dimensions of disruptive innovation results,as well as the regulatory role of the two dimensions of environmental dynamics.The results show that: in the direct effect,the width of external knowledge search and the depth of external knowledge search are both positive to the new market disruption of new start-ups;the width of external knowledge search and the depth of external knowledge search are both positive to the low-end market disruption of new start-ups;moreover,the impact of external knowledge search depth on new market disruption is greater than that of external knowledge search width;the impact of depth of external knowledge search on the disruption of low-end market is also greater than that of breadth of external knowledge search on the disruption of low-end market.In the regulatory effect,market dynamics plays a negative role in the process of external knowledge search width and external knowledge search depth affecting the new market disruption of new start-ups;market dynamics plays a negative role in the process of external knowledge search width and external knowledge search depth affecting the low-end market disruption of new start-ups;technology dynamics plays a negative role in external knowledge search width and external knowledge search depth all play a negative regulatory role in the process of new market disruption of new start-ups;technological dynamism plays a negative regulatory role in the process of external knowledge search width and external knowledge search depth affecting the low-end market disruption of new start-ups.Through the empirical research of this paper,it is helpful for the start-ups to choose the knowledge search strategy purposefully,to choose the type of subversive innovation which is suitable for themselves,and to better implement the external knowledge search to achieve the subversive innovation goal under the dynamic influence of the market or technological environment. |
