产品创新是现代企业保持竞争优势、获得经济利润的有效策略。本文选取四家多次发起同类众筹项目并且后期实现产品创新的企业作为研究对象,运用扎根理论对案例资料数据进行编码分析来研究众筹中如何激发产品创新。研究发现,主体互动通过发起者学习、支持者学习和信息交互实现;与产品创新紧密相关的价值共创形式主要包括共同策划、共同设计、共同测试和共同推广;案例企业均实现了产品创新,即功能创新、形式创新或服务创新;此外,本文构建了理论模型:主体互动促进价值共创过程从而实现产品创新。 相似文献

Although Taiwan is one of the world's leading producers of information products, it lags behind advanced countries in the application of information technologies. The strength of Taiwan's industry lies in its low-cost manufacturing capabilities, which in recent years have been undermined by rising wages. Faced with a massive relocation of production activities to China, the Taiwanese government is trying to prevent the hollowing out of domestic industry by encouraging local firms to embrace new information technologies to strengthen their ties to multinational firms. The initiative aims at enhancing the flexibility of production and speeding up responses to the market through concerted actions by brand marketers, parts suppliers, and assemblers. New technologies underscore new working methods that erect entry barriers to protect existing network relationships. 相似文献

A fault diagnosis method for analog circuit is proposed in this paper. An all-purpose amplifier is taken as the typical circuit under test (CUT). The chaotic signal, which is generated by an improved Chua's circuit, is employed as the excitation signal of CUT. The algorithm for phase-space reconstruction of chaotic time series is a combination algorithm of multiple autocorrelation and Γ-test. The circuit state is estimated based on detecting the geometric change of Chua's attractor with a data-mining approach. For the purpose of information fusion, another eight features are extracted from the testing data to comprehensively determine the CUT states. A discussion is made for comparing the effectiveness of each feature according to the testing results. 相似文献

Current citation-based document retrieval systems generally offer only limited search facilities, such as author search. In order to facilitate more advanced search functions, we have developed a significantly improved system that employs two novel techniques: Context-based Cluster Analysis (CCA) and Context-based Ontology Generation frAmework (COGA). CCA aims to extract relevant information from clusters originally obtained from disparate clustering methods by building relationships between them. The built relationships are then represented as formal context using the Formal Concept Analysis (FCA) technique. COGA aims to generate ontology from clusters relationship built by CCA. By combining these two techniques, we are able to perform ontology learning from a citation database using clustering results. We have implemented the improved system and have demonstrated its use for finding research domain expertise. We have also conducted performance evaluation on the system and the results are encouraging. 相似文献
