摘要：产业集成创新的核心是知识的集成创新，区域产业长期竞争优势的保持与创新发展植根于对区域知识承载力的培育与提升。首先，明确了区域知识承载力的内涵，提出面向产业集成创新的区域知识承载力分析框架；然后，分析了区域知识承载力的影响因素，并通过构建解释结构模型分析了它们之间的相互联系；最后，给出培育和提升区域知识承载力的对策建议。 关键词：区域知识承载力；产业集成创新；影响因素；解释结构模型 一、
摘要：协调失灵是经济生活中普遍存在的现象。现有研究主要探讨个体决策过程中的协调问题，并证明竞争机制有助于解决协调失灵。然而现实生活中很大一部分决策是由群体做出的，群体决策者在竞争环境下的协调行为研究还有所欠缺。文章试图构建一个群体决策情境下的复杂弱链博弈，通过实验研究方法考察群体协调行为，研究发现风险占优策略是群体决策者的稳定偏好，与竞争环境无关。但相比于无竞争设置，在有竞争设置下群体决策的协调成
