Business model innovation faces multiple tests of legitimacy. Most extant research in this area has been conducted from institutional and strategic perspectives while paying insufficient attention to the perspective of evaluators. Based on the institutionalization of China's online car-hailing industry from 2012 to 2018, this paper analyzes the legitimacy judgment of the stakeholders from the perspective of evaluator categorization and explores the legitimation mechanism of business model innovation. It finds that evaluators judge the legitimacy of business models based on category cognition. Therefore, to achieve the bridging, spillover, and accumulation effects of legitimacy, the legitimation strategy of online car-hailing platforms should dynamically adapt to different evaluators, judgment models, and categorization standards. Ultimately, as quantitative changes lead to qualitative changes, the legitimation of innovative business models is achieved in this way. In this process, stakeholders categorize and evaluate online car-hailing based on prototypes and value goals, and establish a two-way interactive mechanism, which is from behavior guided by cognition to cognition given feedback by behavior. This paper combines the legitimacy judgment with category theory to explain how individual cognition drives the emergence of new categories and identifies a series of legitimacy strategies based on categorization, thus providing theoretical support and practical inspiration for exploring the legitimation of business model innovation.

自然资源是绿色发展的基础,产权制度是自然资源高效利用的有力保障.基于绿色发展视角,分析我国自然资源确权登记机制和产权流转机制现存的问题,提出我国自然资源资产产权制度的创新机制:一是通过清晰明确的调查标准、完整的登记信息系统和权属争议仲裁机制构建统一的确权登记制度;二是通过合理的定价机制、规范的产权流转机制和完善的生态补偿机制建立完善的产权流转机制.

The effective distribution of public storage materials is the key to realizing rapid and accurate rescue of territories, which could truly solve the “last kilometer” problem of emergency rescue. At present, it is relatively rare to study the rapid and accurate distribution of emergency supplies by taking demand forecasts, emergency reserves, and distribution models as an organic whole. In view of the bottleneck of rapid and accurate rescue in the complex disaster environment, this paper selects various means such as field research, literature retrieval, and previous case analysis and uses the system analysis method. Next, this paper explains that the three main factors that affect the distribution of public storage materials are the demand of “black box”, the scarcity of materials, and the blindness of distribution and constructs an effective analysis framework of demand predictability, material availability, and distribution accuracy. Finally, this paper puts forward the triangle structure framework of demand forecasting, virtual public storage, and comprehensive distribution and further explains the triangle structure relationship, operation mechanism, and operation strategy of effective distribution of public storage materials.

The response to temperature and glucose, high salt tolerance and self-regulated drug delivery are simultaneously probable by applying a multifunctional microgel in a rational design by a colloid chemistry method. Such smart microgels were fabricated with thermoresponsive N-isopropylacrylamide, glucose-sensitive (2-phenylboronic esters-1,3-dioxane-5-ethyl)methyl acrylate (PBDEMA) and water-soluble crosslinker poly(ethylene glycol) diacrylate through a precipitation emulsion method. These colloidal nanoparticles exhibited PBDEMA-composition-dependent responsive behavior with changing temperature and ionic strength. Amongst them, the microgel with 20.7 mol% PBDEMA with a narrow size distribution is suitable for diabetes treatment because it can adapt to the surrounding medium of different glucose concentrations over a clinically relevant range (0-2.0 mg mL(-)(1)), control the release of preloaded insulin and is highly stable under normal physiological conditions. Preliminary experiments suggest these highly stable microgels have the potential to be used for self-regulated therapy and monitoring the response to treatment. (C) 2018 Society of Chemical Industry
