| In the era of digital economy,the organizational model has undergone major changes,and the platform ecosystem model,which is more open than the traditional bureaucracy and more coordinated than the market,has become the main force of innovation.The innovation activities have no boundaries,the virtualization of innovation cooperation,the difficult definition of innovation knowledge and the dependence of innovation income acquisition are its important attributes.Therefore,the emergence of this model challenges many traditional innovation theories and can solve many problems in this new situation.The service-oriented logic holds that the complementator and platform users jointly create value through resource integration.Whether the complementator can meet user needs and improve user satisfaction from the perspective of users is crucial to its innovation and maintain competitive advantages.Traditional enterprises obtain users’ needs through market research and other methods,which are often inefficient and costly.However,the digital platform ecosystem changes this premise,and users gradually change from passive information receivers to product innovators.The iterative innovation of APP store provides a good scenario for the research of complementator innovation.The change of user demand,the addition and optimization of product functions and even the upgrade of mobile phone operating system all require the complementator to carry out iterative innovation on the APP to adapt to the changes of demand,technology and market.In addition,users can use the app store to post comments to express their needs and opinions to participate in the complementator’s innovation.Therefore,this study focuses on the iterative innovation of APP and discusses the influence mechanism of user participation on the iterative innovation of APP.From the perspective of institutional environment and complementator,we found the situational value of intellectual property protection and complementator scale in user participation and APP iterative innovation.This paper selected the top 800 bestselling apps from IOS platform(China)as the research object,collected the relevant panel data in 2020 and 2021,and used Stata16.0 software to conduct empirical research through descriptive statistical analysis,correlation analysis and OLS regression.The conclusions are as follows:(1)User participation positively promotes APP iteration innovation.(2)Local intellectual property protection weakens the impact of user participation on APP iterative innovation.(3)The complementary scale enhances the influence of user participation on APP iteration innovation.From the above conclusions,this paper draws three management enlightenments:(1)The complementator should attach importance to user participation,listen to the voice of users and even include users in the innovation process in a planned way.(2)The government should continue to improve the knowledge protection system and give play to the role of intellectual property protection in stimulating innovation;However,we should also face up to the crowding out effect caused by too strong intellectual property protection,which impedes the exchange and diffusion of technology.We should proceed in a step-by-step manner rather than in a hasty manner.(3)Smaller complementators need to attach more importance to user participation.We should seize the opportunity to enhance communication with users by means of digitalization,understand users’ needs,clarify users’ pain points,realize curve overtaking through APP iterative innovation,and occupy a place in the market. |
