简介：运用平行面板数据的基本理论，对1996～2005年全国30个省市的地方财政科技投入与地方经济增长的关系进行实证分析，结果表明地方财政科技投入对地方经济发展的影响在各个地区及年份存在着很大的差异。

简介：数据存取延期成为了高端计算系统的突出的性能瓶颈。在系统设计减少数据存取延期的关键是减少数据货摊时间。存储器地区和并发是影响现代存储器系统的性能的二个必要因素。因为全面存储器系统性能上的存储器并发的影响很好没被理解，然而，存在在利用数据存取并发上在很少减少数据货摊时间学习焦点。在这研究，一双新奇数据货摊时间模型，为地区和并发的联合努力的L-C模型和为数据上的纯失误的效果的下午模型阻止时间，被介绍。模型提供数据存取延期的新理解并且为表演优化提供新方向。基于这些新模型，先进缓存优化的一张概括表格被介绍。当时，被数据并发贡献了，把38个条目仅仅，21个条目由数据地区作出贡献，它显示出数据并发的值。在这研究介绍的L-C和下午模型和他们的联系结果和机会为数据中央的建筑学和算法现代计算系统设计的未来重要、必要。

简介：本文通过建立混合面板模型，对中国各省市金融发展状况和城乡收入差距进行分析。并将金融发展指标细化，从不同角度验证金融发展与城乡收入差距的关系。结果表明，金融发展规模和股票市场规模能够缩小城乡收入差距，而金融发展效率与之相反。在此基础上，我们结合实际情况，从金融发展角度出发，提出了缩小城乡收入差距的建议。
