网络嵌入性、粘滞知识转移与企业合作创新

以企业合作创新为研究对象,引入粘滞知识转移作为中介变量,分别从关系嵌入、结构嵌入的网络嵌入性维度,构建影响企业合作创新的概念模型。研究发现:企业通过关系嵌入和结构嵌入能很好地推动合作创新所需要的粘滞知识转移,从而成功实现企业合作创新。粘滞知识转移在关系嵌入对合作创新的影响过程中发挥着部分中介的作用,而粘滞知识转移在结构嵌入对合作创新的影响过程中发挥着完全中介的作用。     

论企业知识员工的嵌入式管理

知识员工的物质追求、精神追求等是以其所拥有的知识技能为基础的,如果企业为知识员工提供知识技能发挥以及知识持续增长的平台,使得知识员工形成自我成长依赖并嵌入于企业内部形成的知识实践社群,必然会取得良好的效果。     

Parametric prediction on default risk of Chinese listed tourism companies by using random oversampling,isomap, and locally linear embeddings on imbalanced samples

This research pioneers the default risk parametric prediction of Chinese tourism companies with random oversampling and manifold learning for parametric modelling on imbalanced samples to relax the requirement on sample availability. Four specific approaches were employed: standardization; standardization → random oversampling; standardization → isomap + locally linear embeddings; and standardization → random oversampling → isomap + locally linear embeddings. Empirical results indicate that: random oversampling successfully improved the tourism default risk prediction; the integration of isomap and locally linear embeddings is beneficial in default risk prediction using highly skewed tourism data with absolute minority samples; and after the use of random oversampling on initial data, the integrated approach improved in forecasting tourism default risk prior to two years versus one year.
