RECENT DEVELOPMENTS IN THE THEORY OF NATURAL MONOPOLY

Abstract. This paper examines two important recent developments in the theory of natural monopoly, or more generally the theory of market structure. The first is a series of papers, involving Baumol with various co-authors, investigating the theory of industry structure, whilst the second is particularly associated with the names of Shaked and Sutton, and the relationship they develop between product differentiation and industry structure. The paper surveys and to some extent contrasts these two new approaches.
Baumol et al. 's contribution is seen to be in the area of clarifying the concept of natural monopoly, refining the definitions of multiproduct costs, and developing a notion of social efficiency applicable to industries where economies of scale are important. Shaked and Sutton employ a new definition of natural monopoly unrelated to market size and utilize information about consumers'income distributions to develop their notion of vertical product differentiation and natural oligopoly.

浅析产业集群下的“苏州模式”

“苏州模式”是随着苏州经济的飞速发展而渐入人们的视野。但究竟什么是“苏州模式”，至今没有一个权威统一的概念。从产业集群理论出发，从集群产生和演化方面分析，可以得出苏州模式政府主导的嵌入型特点；通过分析苏、温两地产业集群的主体，得出苏州模式下外资电子信息产业集聚的事实；从分析生产方式入手，得出了苏州刚性生产的特性，通过分析集群内企业网络特点。结论是苏州模式大致有契约性、区外网络和“核”状网络等特点。

The coevolution of firms and their knowledge environment: Insights from the pharmaceutical industry

What are the most effective learning strategies for firms given the characteristics of their knowledge environment? This paper addresses this question by documenting the major changes in the knowledge environment of the pharmaceutical industry, with a particular emphasis on the period since the emergence of biotechnology, and discussing the related changes in the learning strategies of established pharmaceutical firms. Both the historical analysis and a review of the empirical research on organizational learning and knowledge transfer reveal a strong emphasis of firms on external learning through interfirm collaborations and sourcing of external knowledge. This learning strategy seems to be driven by the speed, uncertainty, and dispersion of knowledge developments in the industry. Studying the connections between the knowledge environment and the effectiveness of organizational learning processes is important to understand organizational change and adaptation, and is an area of research that deserves further attention.

循环经济视角下的产业结构调整途径

从发展循环经济的视角看,我国的产业结构调整还存在忽视资源环境的禀赋性、忽视产业结构性污染、忽视产业内部结构层次提升、忽视产业结构体系的完整性等不足之处。调整产业结构必须坚持循环经济理念,要求构建新型产业结构系统,促进产业结构的合理化和高级化。基于此,循环经济视角下的产业结构调整途径主要有:积极发展地区资源特色产业,实现资源优化配置;全面调整产业结构布局,克服结构性污染;优化产业内部结构,促进节能降耗和积极发展生态产业,完善产业结构体系等。     

创意产业促进城市发展的内容与途径
