警惕我国企业集群发展中潜在问题 总被引:4,自引:0,他引:4
企业集群是当今区域经济发展规划的新趋势 ,引起了多学科领域学者关注。我国已经出现了一些企业集群的雏形 ,但是这些企业集群都存在不同的问题。以东莞、温州及部分的高新区为例 ,从各自的形成过程、发展轨迹等角度 ,讨论了各具特色的区域集群存在的不同性质的问题 相似文献

This paper analyzes regional determinants of the start-up ratio in the Japanese manufacturing sector. A major contribution
of this study is the comparison between high-tech and low-tech industries. The empirical results using a sample of 253 industrial
districts suggest that business density, weight of the manufacturing sector, and the average business size significantly influence
the start-up ratio in both high-tech and low-tech industries. Distinct differences between these industries were found with
regard to the effects of human capital, research institutes, and the weight of high-tech industries.

The purpose of this paper is to present a closed formula to compute the moments of a general function from the knowledge of
its bivariate survival function. The result is derived by utilizing an integration by parts formula for two variables, which
is not readily available in the literature. Many of the existing results are obtained as special cases. Finally, two examples
are presented to illustrate the results. In both the examples, mixed moments as well as moments for the series system and
parallel system are obtained. The integration by parts formula in two variables, derived here, is of interest in its own right
and we hope that it will be useful in other investigations. The integration by parts formula in two variables is derived as
a special case of a general formula in n variables. 相似文献

2002~2007年间,中国制造业的原材料、工资等成本出现大幅度上涨,但与此同时,制造业的利润总额与利润率仍然呈增长趋势。本文利用投入-产出方法对中国制造业的“成本上涨与利润增长并存”之谜给予解释。本文的研究表明,投入(特别是原材料)价格与工资上涨造成制造业利润的减少,但通过提高产出的价格以及调整投入的结构、提高投入的使用效率能够消化成本上涨的影响,从而保持利润的增长。对成本上涨做出调整的过程也是产业升级的过程,2002-2007年间,中国制造业绝大多数行业的资本劳动比、全员劳动生产率与全要素生产率都有了显著提高。由于应对成本上涨空间的有限性,应进一步加快中国制造业产业升级的步伐。 相似文献

Regional economic disparity is a hot issue in the development of society and economy.As the conjunct of the Yangtze River Delta and the Pearl River Delta and the frontier to Taiwan,the west coast of the Taiwan Strait (WCS) is of great social and political significance.The paper defines" the connotation of the WCS,decomposed the regional economic disparity by using weighted coefficient of variation and Theil coeJficient,and explores the industrial and regional source of the regional economic disparity of the WCS.The analysis results show that:(1) the WCS has important political,economic and military position,so it's better to regard it to be comprehensive region,not just refer to Fujian Province;(2)from the industrial decomposition of weighted variation coefficient,the influence of the primary industry was tiny,conversely,the development inequity of the secondary and the tertiary indus'try was the main source of regional economic disparity.Their contribution has had the converse trend and the secondary contribution has gone beyond the tertiary since 2003;(3)from the regional decomposition of Theil coefficient,the regional economic disparity mainly came from inter-area inequity of 4 areas.Moreover,the inner economic disparity mainly drove by Fujian,suggesting that the urban development inequity in Fujian Province was comparatively outstanding. 相似文献

能源价格对宏观经济的影响——基于可计算一般均衡(CGE)的分析 总被引:28,自引:1,他引:28
石油与煤炭价格上涨将对中国经济造成什么样的影响,其影响度与中国现阶段的经济特点的相关性,以及如何应对能源价格上涨的影响,都是政府宏观决策需要研究的重大问题。本文运用CGE方法研究了这些问题,尤其是对石油与煤炭价格上涨影响程度的对比,填补了这一方面的研究空白。结果表明:能源价格上涨对中国经济具有紧缩作用,但对不同产业的紧缩程度不一致,能源价格除了影响经济增长,还将推动产业结构变化。对大多数产业而言,相同比例的价格上涨,煤炭的紧缩作用是石油紧缩作用的2至3倍;对于非能源密集型的服务业紧缩幅度也达3倍,石油和煤炭的经济紧缩作用程度不一致与目前中国能源消费结构基本吻合,2007年中国煤炭消费占一次能源的70%,而石油消费仅占20%。本文最后就如何应对能源价格上涨的影响提出建议。 相似文献

The “territory” is widely recognized in the literature on business strategy as a critical driver of industrial competitiveness (see, as an example, Porter, The Competitive Advantage of Nations). The generation and exploitation of new knowledge, both tacit and explicit, through the process of socialization, articulation, combination and internalization (see Nonaka and Takeuchi, The Knowledge-Creating Company) is essential to enable innovation of processes and products of “local” firms.Our recent Foresight exercises in the metal working and machinery district of Lecco and in the silk district of Como show that Foresight can play an important role in creating and exploiting new knowledge, and that different methodologies can be more or less effective to this aim.Critical technology list and interactive workshops, with the participation of entrepreneurs of SMEs and technologists, are more suited to foster the transfer of technologies that have overcome the initial stage of the life cycle and that have been already applied in other sectors. However, when radical innovations are needed in order to face the challenges posed by global competition, other methodologies, as Scenarios, are more appropriate. Even if these approaches are complex and time and resource consuming, they may be very effective in actively involving the most relevant private and public stakeholders of a district, and in making them to envisage the long term future of the economic, social, and cultural structure of their district. In this way Foresight drives the small entrepreneurs, the district stakeholders and the medium and large size firms to play the critical roles of Nonaka and Takeuchi's “frontline employees”, “senior managers” and “middle managers” in their “knowledge creating company”: the first ones grasp what the district is; the second ones build the vision of what it ought to be; the third ones, serve as a bridge between the future and the present. 相似文献

East Asian development experience provides the basis for understanding which are the essential elements of effective technology strategy and policy, those that are required for the efficacious development of countries that have not yet embarked on a path of sustained modernization. Globalization has had a profound impact on development, enabling countries that could exploit its propelling forces to pursue a potent strategy of export-led economic and technological development. The policies needed to sustain this strategy are those required to foster institutions that permit effective commerce among economic agents, those necessary to generate the rapid accumulation of human and physical capital, and those essential to ensure that resources are allocated in accord with the economy's dynamic comparative advantage. Of crucial importance among the latter are effectively implemented policies of selective intervention designed to develop infant industries and to foster their fast-paced achievement of international competitiveness through rapid attainment of the requisite technological capabilities. 相似文献

This paper presents an agent-based simulation model with local network externality to analyze strategic interactions over
investment on new economic knowledge. R&D knowledge flows and spillovers are the results of non-cooperative games played between
neighboring agents in the model. The model demonstrates a situation where no agents have incentives to hide their economic
knowledge, a situation that is observed in open source software development projects. The likelihood of obtaining a stable
situation where new economic knowledge is openly shared is increased when heterogeneity of agents is introduced.
