Using Spatial Lag Model and Spatial Error Model, a spatial econometric analysis on institutional spillover effect of marketization degree in China's provinces and the effect on regional economic growth is performed. The results of spatial analysis show that after nearly 30 years' development of China's provincial economies reform and opening, the spatial association becomes closer while geographical clustering obviously intensifies, and the institutional spillover effect among the provinces becomes confessedly.
摘要本文从空间分析的角度研究各地区市场化进程的空间效应及其对区域经济增长绩效的影响,空间计量经济分析的结果表明市场化进程的空间分布在整个样本区间与GDP、资本和劳动一样呈现出集聚的趋势,区域差异显著,各地区的市场化进程在地理空间上存在显著的自相关关系,证实了各地区市场化进程存在制度溢出效应。

And has done the tired life test of the hypoid gear. As the samples of the test data of gear life test is very few, the author has made the error model of tes tinghypotheses when using k-s method, the auther presented a testing hypotheses method which can make use of the information of the samples and reduce the error of probability Calculation. It is Called"the improved K-s method". The author has used this method to deal witch the life test datas and the result is identical with the result of the theoretical calculation.
