This paper make a general analyze of the SMES Cluster, define the conception of SMES Cluster, the forming of SMES Cluster and the basic types of SMES Cluster, study the important function of the SMES Cluster to the country, the district and the enterprises selves.Second, this paper research comparatively of three different international SMES Cluster cases and three different domestic SMES Cluster cases. Three different international SMES Clusters include the Italianism SMES Cluster, the Croatia SMES Cluster and the SMES Cluster which are formed by the multinational corporations" investment. Three different domestic SMES Clusters include the Zhejiang province SMES Cluster, Shandong province SMES Cluster and the Zhongguancun SMES Cluster.Finally, on the basic of analysis in cases, according to the current situation of Jiangsu and analysis of cluster development condition of SMES, explore the SMES Cluster development mode and pattern in Jiangsu. The main types of SMES Cluster in Jiangsu include Spontaneous growing up type, enterprise"s expanding type, market driving type, urging type of science and technology, and driving type of the foreign capitals.

本文通过对中小企业集群的一般分析，界定中小企业集群的概念、形成、基本类型以及中小企业集群对国家、对区域、对企业本身的重要作用；其次，对国外三种不同类型的中小企业集群(意大利式中小企业集群、克罗地亚造船厂式中小企业集群、跨国公司投资形成的中小企业集群)和国内三个不同地区的中小企业集群(浙江省中小企业集群、山东省中小企业集群、中关村中小企业集群)的案例进行比较分析研究；最后，在案例分析的基础之上，根据江苏的现状以及中小企业集群发展条件的分析，探索江苏集群发展的模式和格局，江苏的中小企业的发展模式主要有自发成长型、企业扩张型、市场带动型、科技驱动型、外资带动型。

The following is the research frame of this dissertation:Chapter one: Introduce background, research significance, research object, research contents and methods of this dissertation; review the history of clusters theoretical research in detail; dissertate main research dynamic status of domestic and international;Chapter two: Through explain theoretical foundation of cluster research, it defines and demarcates clusters, introduces the concept of private enterprises" cluster on this basis, and summarizes current situation of Quanzhou private enterprises" cluster;Chapter three: Propose the concept of cluster competitiveness, collect and analysis those factors which influence cluster competitiveness, and set up an appraisal system of private enterprises" cluster competitiveness;Chapter four: Define developing stages of private enterprises" cluster with clusters" dominance competitiveness, analysis characteristic and law of private enterprises" cluster in different life cycle, give out strategic countermeasures separately which promote cluster competitiveness in different stage;Chapter five: On the basis chapter three and chapter four, propose what we can use cluster strategic planning to promote Quanzhou cluster competitiveness; and recommend thought of cluster strategic planning;Chapter six: Introduce the case of Quanzhou sports shoes cluster, use competitiveness appraise system and life cycle theory for empirical analysis, and put forward detailed countermeasure that can promote cluster competitiveness;Conclusion: Summarize the research of full dissertation, and point out some weaknesses of this dissertation.

Firstly,the sampling design has great impact on the accuracy of remote sensing classification.There exists great randomicity on the result of points and cluster sample verification on the different Sampling design.On the same sampling design,the stability of point sample verification is higher than that of Cluster sample verification.Secondly,the average accuracy of different sampling designs of multi-point and multi-cluster sample verification can reflect the accuracy characteristic.During the course of point sample verification,stratified sampling's error is lower than others'.During the course of cluster sample verification,systematic sampling and stratified sampling's accuracy are prior to simple random sampling's.

研究结果表明：（1）抽样方式对遥感分类精度评价结果的影响是客观存在的，不同抽样方式下的点样本和群样本检验结果都存在一定的随机性，但同一种抽样方式下，点样本检验精度评估结果的波动幅度小于群样本检验，稳定性比群样本检验要好；（2）不同抽样方式下的多次点样本和群样本检验的平均精度检验结果基本上都能够反映分类图像的精度特征，其中，点样本检验中，分层随机抽样点样本检验效果较好；群样本检验中，系统抽样群样本检验和分层随机抽样群样本检验的效果优于简单随机抽样群样本检验。
