摘要:文章采用结构方程的分析方法,分析了企业经营战略对我国中小企业国际化绩效的影响进行了研究。研究结果表明:在企业国际化进程中,企业经营战略的替代难度、投入成本和共同发展因子都对企业财务绩效有显著影响;只有共同发展因子对非财务绩效因子影响显著。文章的研究方法和研究结论对我国中小企业的国际化实践具有重要理论和现实指导意义。  关键词:企业经营战略;财务绩效;非财务绩效;结构方程  一、 引言  伴随
石油作为一种战略性资源,越来越成为世界关注和争夺的焦点,石油资源的短缺也成为制约我国经济可持续发展的最大障碍。而缓解我国资源短缺的对策之一,就是促使石油企业“走出去”

摘要:文章旨在研究廉租房与公租房并轨可能引起的问题,为租赁型保障房的后续完善提供政策建议。运用情景模拟方法,文章从资源配置效率、制度运行成本、财政压力、公共治理等视角对两房并轨政策自身及实施中可能出现的问题进行了理论剖析。研究发现,尽管有不少优点,但两房并轨可能存在帕累托改进难度大、保障对象信息甄别成本增加、财政负担加重、总房源供应监督难、公众信任度弱化等问题。文章还为租赁型保障房的完善提供了政策
