本文运用传统的国际贸易理论—比较优势理论以及迈克尔·波特教授的竞争优势理论对我国加入WTO后纺织业行业的现状、面临的各种竞争作用力和纺织行业具体存在的问题进行了分析，进而提出我国的纺织业具有比较优势，但是缺乏核心竞争优势的结论。

The major dominant species of predatory enemies were Erigonidium graminicola and Theridion octomaculatum and their individuals were 81.4 percent of the total predatory enemy individuals of the community.1.2 Spatial patterns and their dynamics of major dominant predatory enemies ofarthropod communityThe research results showed that Pieris rapae distributed mainly on heart leaves and back of inner leaves of cabbage plants, Plutella xylostella distributed mainly on the back of cabbage leaves and Lipaphis erysimi distributed widely in cabbage plants. Among the major dominant species of predatory enemies, Sitticus sinensis distributed mainly on the front of leaves of cabbage plants in spring cabbage fields, and Misumenopos tricuspidata and Propylaea japonica distributed widely in cabbage plants.

在捕食性天敌中蜘蛛10种，捕食性昆虫3种，主要优势种为草间小黑蛛、八斑球腹蛛，其数量占捕食性天敌总数量的81.4%。1.2节肢动物群落主要优势种的空间格局及其动态研究结果表明，害虫优势种菜青虫主要分布于甘蓝心叶和甘蓝叶反面，小菜蛾主要集中分布在甘蓝叶的反面，而菜蚜在甘蓝植株内的分布较广；春甘蓝田捕食性天敌优势种中华跃蛛在外层叶正面分布较集中，三突花蛛与瓢虫类在甘蓝植株内的分布较广。

3Through analysis of the calculate results and actual fact of Shaanxi province, we can still attain below information: The latest rank of index of new economy in China shows: Shaanxi is the eighth, but the GDP per person is NO.29, so the technology and resource advantages of Shaanxi are far to convert to economic advantage, Finally, how to make the technology of the Shaanxi converting to realistic productivity farthest, and make the technology advantage converting to economic advantage, and make the big province of technology becoming a powerfully economic province which is worthy of the name, the dissertation suggests grasping a few aspects as follows: Set up the idea of exploitation new technology, establish the motive mechanism of technology innovation, establish the mechanism of guarantee the budget of scientific research, establish the mechanism of guarantee scientific personnel, construct the fair competition market environment, allotment technology resources openly in the most possible, make the resources to be allotted and used with high-efficiency, at the same time, relying on the resources advantage of Shaanxi, proceed the technique reform and technique penetration, so as to creates the higher benefit.

最后，就如何使陕西的科技优势最大限度地转化为现实生产力，使科技优势转化为经济优势，使科技大省成为名副其实的经济强省，笔者建议从以下几个方面抓起：树立新的科技开发观念、建立科技创新的动力机制、建立科研经费保障机制、建立科研人员保障机制、营造公平竞争的市场环境，科技资源分配尽可能地公开，使资源得到较高效率的配置和使用，同时，依托陕西的优势资源，进行技术改造和科技渗透，以创造出更高的效益。本研究具有以下创新点：一是使用先进的研究方法，把计算机计算和新的数学方法相结合，使计算简单化、准确化；二是使用了先进的研究思路，把陕西省和其他地区置于同一系统内，使用同一的数据处理方法和统计口径，使计算结果更科学、更符合实际，且具有可比性。

On the basis of regional division and cooperation, it outstands itself with resources-acquiring, market efficiency, innovative, startup as well as expansion, all of which have greatly stimulated the economy growth of coastal areas in China.

The results showed that Liquidamba formosana, Quercus acutissima, and Quercus fabri populations had the dominant positions in the forest community of Purple Mountain Area of Nanjing. During the growth process, the mortality of L. formosana, Q. acutissima, and Q. fabri were higher in low age. After entering into the middle-age stage, the upper space was occupied by oak and L. formosana population all died. The mortality of Q. acutissima and Q. fabri populations were increased with the increasing of diameter class. L. formosana population in the Purple Mountain Area of Nanjing belonged to be the typical growing population and Q. acutissima population was a decreasing population. Q. fabri population belonged to be the growing population on the whole, but the diameter class in middle parts was incomplete and the population was difficult to be renewed. Among the studied quadrate, only one dominant population showed an aggregated distribution and other dominant species showed the random distribution. Either, all the dominant species in all the quadrates presented random distribution.

结果表明，枫香种群、麻栎种群和白栎种群在南京紫金山地区森林群落中占有优势地位；枫香种群、麻栎种群和白栎种群在其生长过程中，在低龄时期，死亡率都较高，进入中龄期后，由于上层空间都被栎木占据，枫香种群全部死亡，而麻栎种群和白栎种群的死亡率则随着径级的增大而增大；南京紫金山地区枫香种群属于典型的增长型种群，麻栎种群属于衰退型种群，白栎种群总体上属于增长型群落，但中间径级不完整，种群更新较为困难；在所研究的每一个样方中，一般只有一个优势物种呈聚集分布，而其他优势物种呈随机分布，或样方中所有优势物种都呈随机分布。

The shared resource not only has significant positive impact on the competitive advantages of the firm in the cluster, but also has indirect negative impact on the competitive advantages of firms in cluster. The mechanism of the shared resource acting on the competitive advantages of the firm in the cluster is complicated.4 The rigidity of shared resource can be reified to different kinds of rigidities, and different kinds of rigidities have different modes of effecting on the competitive advantages of firms in cluster.

共享性资源对集群企业竞争优势不仅具有正向作用，还可以通过共享性资源刚性对集群企业竞争优势产生负向作用，因此，集群企业竞争优势水平是共享性资源对其多种路径共同作用的结果；(4)共享性资源刚性可以分解出各种不同类别的具体刚性要素，不同的刚性要素对集群企业竞争优势产生作用的路径不同。
