| New platform organizations are becoming the main body of social and economic operation in the digital era.At present,Chinese firm are facing challenges such as weak digital foundation and low innovation efficiency.In order to cope with the increasingly fierce market competition and effectively improve their own innovation performance,more and more firm choose to improve their competitiveness with the help of digital platform system.China is both an industrial power and an Internet power.The IIo T platform promotes the integration of industry and the Internet and has become an important driving force to improve the innovation efficiency of Chinese industrial firm.Knowledge is the key resource to improve the innovation level of firm,and there are serious repetitive innovation problems in industrial firm,which reflects the insufficient knowledge flow and utilization efficiency among industrial firm.The essence of IIo T platform is to reconstruct the new knowledge division system of industrial knowledge creation,dissemination and reuse,and promote the rise of knowledge market based on industrial scenario.Among them,a large number of cross industry and cross field industrial experience,knowledge and methods will be precipitated on the IIo T platform in the form of industrial APP,industrial components and solutions to realize free embedding with the core modules of the platform.The emergence of the IIo T platform marks the evolution from the product-based industrial division system to the knowledge-based ecological division system.Its value lies in that in the process of traditional industrial innovation,repetitive innovation activities that consume a lot of resources of firm will continue to decrease.firm can reduce the risk of many exploration and trial and error in the process of innovation by trading and reusing mature knowledge,so as to focus on creative activities in their own advantageous fields.The development of China's IIo T platform has achieved certain results,but it still faces many problems.From the perspective of users and firm,it is prominently reflected in the two aspects of "dare not use and can't use".The problem of "dare not use" is reflected in the firm's concern about the uncertainty of the platform function and cooperation with the platform,and the problem of "can't use" is reflected in the reduction of practical effect caused by unclear understanding of the platform knowledge enabling function even if they participate in the platform interaction.These two kinds of practical problems seriously restrict the willingness and effect of user firm to participate in the IIo T platform.The emergence of practical problems has opened up space for theoretical research.Many scholars have carried out research on the situation of digital platform.However,the existing research can not effectively explain the above problems,mainly because the current research on platform firm and platform ecosystem in the field of management is mostly based on the attribute of trading platform,that is,it emphasizes that the platform builders build a digital interactive space for the platform participants,and promote the exchange of products,information and knowledge among various participants in the space.Thus,it increases the acquisition of heterogeneous knowledge of participants,promotes the internal knowledge creation of firm,and finally improves the novelty of firm innovation.There are three deficiencies in the research based on the above logic: first,the innovation logic reflected by the research based on the attributes of trading platform can not explain the reasons for the above problems of user firm in IIo T platform;Second,the existing research contains an implicit assumption that firm playing the role of value co-creation already have a certain digital ability.However,the digital level of Chinese industrial firm is generally low,and most of them have not been connected to the digital platform,which highlights the difference between the existing research and practice;Third,the overall research based on ecosystem theory mostly focuses on the platform itself or the platform construction of the platform owner.It is difficult to study the practical problems faced in the process of application platform from the perspective of user firm,and it is more difficult to give theoretical guidance.In order to make up for the above research deficiencies,this paper intends to start from the attributes of technology-based platform,sorts out the situational characteristics of IIo T platform,and then explore the factors affecting the innovation performance of user firm based on the situational characteristics.The physical architecture of IIo T platform determines that it has significant technical platform attributes.The technology platform theory points out that the technology-based platform is not the platform considered by the bilateral market theory,which only simply provides intermediary transaction matching services.It should have a stable and less changeable core,make modular connection with external changeable complementary firm through certain rules,and obtain complementary resources provided by the outside,And then provide proprietary services to user firm.The attribute of technology-based platform determines the "radial" relationship between the platform and user firm,and also determines the knowledge system characteristics of the platform,that is,the platform provides modular knowledge to users,users acquire knowledge through transactions,and avoid repetitive innovation through reuse,so as to improve the efficiency of innovation.On the basis of situational characteristics,through case studies,this paper finds that firm that successfully realize innovation and upgrading with the help of IIo T platform generally have two commonalities: first,they are full of confidence in cooperation with the platform and have high enthusiasm in the process of cooperation;Second,compared with the product supply and marketing channels provided by the platform,these successful firm pay more attention to the knowledge enabling effect brought by the platform.Therefore,this paper believes that in the context of IIo T platform,the trust of user firm in the platform is the key factor affecting their innovation performance,and the Knowledge trading and reuse behavior of user firm are the key path for trust to promote innovation.The two key factors of inter-firm trust and knowledge management behavior extracted from the case study are the effective answers to the two practical problems faced by user firm in the practice of IIo T platform,that is,user firm strengthen their trust in the platform and actively carry out knowledge trading and reuse behavior,which is an effective way to realize innovation and improvement.In addition,both the user firm as internal factors,and the platform as the external environment,also have impact on the practice process of the user firm.However,there is no formal institutional control relationship between the platform and user firm.At present,most IIo T platforms are firm level platforms,and the builder of the platform is the core firm occupying the central position of the network(for example,the core firm in the COSMOPlat is the Platform Builder Haier Group),Therefore,the core firm leadership based on resource dependence logic can be reflected as platform leadership in this paper,which has become the main way for the platform to affect users.Through the application of transaction cost theory,inter-firm leadership theory and knowledge management theory,this paper hopes to provide theoretical support for the research to explain the above complex relationship.The research conclusion can pay attention to the trust of the platform for user firm participating in the IIo T platform,so as to promote the knowledge trading and reuse of user firm.And then provide scientific and reasonable suggestions to improve the innovation performance of user firm.Under the theoretical and practical background,taking the IIo T platform as the research situation,this paper focuses on the core issue of "how inter-firm trust promotes the improvement of user firm innovation performance".Firstly,this paper selects three typical IIo T platforms in China,and selects a representative user firm from their public cases.Through the analysis based on grounded theory,this paper puts forward the research model of "Inter-firm trust-knowledge trading and reuse of user firm-innovation performance of user firm",and introduces platform leadership as an environmental influencing factor.Secondly,by studying the existing literature,this paper combs and integrates the concepts of inter-firm trust,user firm knowledge trading,user firm knowledge reuse,user firm innovation performance and platform leadership,puts forward hypotheses and carries out empirical tests.Finally,the hypothesis is analyzed and discussed according to the empirical results,and the main conclusions of this study are drawn.The results show that:(1)Inter-firm trust has a positive impact on user firm innovation performance.(2)Knowledge trading and reuse of user firm plays an intermediary role in the relationship between inter-firm trust and user firm innovation performance.(3)User firm knowledge trading and user firm knowledge reuse play a continuous intermediary role in the relationship between inter firm trust and user firm innovation performance.(4)Platform leadership positively regulates the relationship between inter-firm trust and user firm knowledge trading,and between inter-firm trust and user firm knowledge reuse.To sum up,based on the case study focusing on user firm,this paper has some practical enlightenment for the majority of firm participating in the IIo T platform to overcome the problem of "dare not use or can not use".In addition,based on the transaction cost theory,this paper explores the changes of strategic innovation theory in the context of new platform organization,and expands the research content of transaction cost theory;Analyzing the improvement of firm digital level from the perspective of knowledge management,which expands the application situation of knowledge management theory;At the same time,the application of inter-firm leadership theory explores the impact of platform leadership in the practice of users' firm,and extends the function logic of leadership theory among firm.Therefore,the research has certain theoretical significance. |
