Customers' online value co‐creation activities can occur the whole management domain (i.e., product design, marketing, and customer relationship management) of a product. Previous studies have researched value co‐creation from different angles, customers' online value co‐creation activities are more complex and its formation mechanism still worth exploring. Online communities need to create different environments according to different management fields to stimulate customers to participate in Online Value Co‐creation activities. Existing research confuses different value co‐creation activities in the entire management field without considering the different antecedents of Online Value Co‐creation activities in different situations and different management domains. The purpose of this paper is to explore the formation mechanism behind customers' online value co‐creation activities during the whole management domain. Drawing on social learning theory, this study examines the influential role of environmental factors (i.e., innovation climate and social climate) of online communities and personal need factors (i.e., brand passion, satisfaction, dissatisfaction, and desire for control) on customers' value co‐creation activities in the three fields of the management domain. Empirical analyses in this study reveal that these factors play different roles in shaping value co‐creation activities in the three fields. The findings enrich our understanding of customers' value co‐creation activities in online communities and offer a broadened view of the value co‐creation framework and climate theory. Understanding the factors that motivate consumers to engage in co‐creation activities in different management domain enables firms to strategically manage their co‐creation relationships and innovation processes.
A single-zone HCCI combustion model coupled with chemical reaction kinetics mechanisms was set up by AVL-BOOST and CHEMKIN module based on a variable lift and timing (VLT) gasoline. In order to achieve HCCI combustion, the negative valve overlap (NVO) strategy was used to raise the temperature of mixed air in the simulation. In this paper, the HCCI combustion was compared with the conventional SI combustion, then the feasibility of using single-zone model to simulate the HCCI combustion was verified and the HCCI operation region was predicted under specific speed, compression ratio, air-fuel ratio conditions by this model.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
