我国产业集群促进实践中的问题研究——基于欧洲各国的集群政策经验

将我国地方政府与欧洲各国地方政府集群促进与政策实践比较之后发现,政府在集群促进中的角色设定上,在集群运行机理认识上,在政策工具运用上,在集群识别与支持对象选择上,在政府集群促进行动方式上,在政府对于集群资助方式上均存在着较大差异。分析讨论表明,这些差异主要不是因为国情不同,或体制不同造成的,而是因为地方政府对市场经济不适应造成的,进而揭示并讨论了我国一些地方政府集群促进政策实践中的问题。     

Editor's Report

There are two common methods for statistical inference on 2 × 2 contingency tables. One is the widely taught Pearson chi-square test, which uses the well-known χ²statistic. The chi-square test is appropriate for large sample inference, and it is equivalent to the Z-test that uses the difference between the two sample proportions for the 2 × 2 case. Another method is Fisher’s exact test, which evaluates the likelihood of each table with the same marginal totals. This article mathematically justifies that these two methods for determining extreme do not completely agree with each other. Our analysis obtains one-sided and two-sided conditions under which a disagreement in determining extreme between the two tests could occur. We also address the question whether or not their discrepancy in determining extreme would make them draw different conclusions when testing homogeneity or independence. Our examination of the two tests casts light on which test should be trusted when the two tests draw different conclusions.     

Fast and Stable Algorithms for Computing and Sampling From the Noncentral Hypergeometric Distribution

Although the noncentral hypergeometric distribution underlies conditional inference for 2 × 2 tables, major statistical packages lack support for this distribution. This article introduces fast and stable algorithms for computing the noncentral hypergeometric distribution and for sampling from it. The algorithms avoid the expensive and explosive combinatorial numbers by using a recursive relation. The algorithms also take advantage of the sharp concentration of the distribution around its mode to save computing time. A modified inverse method substantially reduces the number of searches in generating a random deviate. The algorithms are implemented in a Java class, Hypergeometric, available on the World Wide Web.     

集群剩余与企业集群内部协调机制

企业集群内部协调既不同于市场上价格机制的无形之手,又不同于企业内部行政命令的有形之手。本文分析指出,集群内部协调的目标在于追求集群剩余,并根据企业行为的规律性对集群剩余进行了分析;介绍集群内部的各种协调机制,在此基础上,分析协调机制与集群剩余实现之间的关联。     

产业集群中跨国子公司战略地位与母子关系的演进

本文首先基于理论分析,指出优势产业集群中的跨国子公司完全有可能成为跨国公司竞争优势的来源。由此,文章分析了集群中跨国子公司存在的四类知识流以及影响四类知识流方向和流量大小的三种重要影响因素,并根据后两个因素区分了集群中子公司在跨国公司内部战略地位上的差异。基于战略与结构的孪生性,本文论述了集群中跨国公司母子关系的变迁,分析了集群中子公司的双重根植性。     

合理产业结构的确定方法及预测

本文根据技术矩阵决定产业结构的思想,给出了不编制投入产出表年份的合理产业结构的计算方法及预测未来年份合理产业结构的计算方法。并将该方法应用于山东省合理产业结构的确定及预测。方法简便,易操作,且计算结果较理想。     

日翻九楼夜演孟姜--绍兴孟姜戏初探

绍兴旧抄《孟姜女》为绍兴道士孟姜班专演剧目,只限于班内相授,秘不外传。向无刻本,历来手抄,凡四十一出,现存为民国八年六月上虞县小坞村孟姜班抄本。原唱高腔,后改为乱弹。其有别于其它同题材剧目之处在于:在内容上吸收了大量佛、道二教超度亡灵的仪式,在演出上配合内坛“洪楼炼度”法事,接白天的“翻九楼”而于当晚的下半夜演出,故有“日翻九楼,夜演孟姜”之称。综观全剧,具有以幽法为载体、以超度为宗旨、与翻九楼相衔接三大特点。     

从“帖雅娜现象”谈高校高水平乒乓队的若干问题

中国各地区经济发展水平的实证分析

利用1995-2006年数据,采用时序多指标综合评价法,对中国各地区经济发展水平进行评价研究。结论表明：虽然中国1995-2006年经济增长迅速,但是经济发展水平并未得到显著提高;各地区经济发展不均衡,地域差距较大且有逐年扩大的倾向。     

A time series approach to life table construction

This paper deals with the construction of the life table. A discussion of basic facts about the life table is followed by the proposal of a nonstationary, autoregressive model for the life table. The moment structure of the nonstationary, autoregressive model is developed. Some estimation procedures are proposed followed by several examples.
