An Econometric Estimation of Industrial Water Demand in France

This study investigates the structure of industrial water demand byestimating the derived demand for water on a sample of industrialestablishments located in the south-west of France. Productiontechnologies are represented by short-term variable cost functions andapproximated by a translog form. Industrial water use is modeled ashaving three components: the quantity of water bought to a waterutility, the quantity of autonomous water and the quantity of watertreated prior to use. We include in this framework water effluents,which are considered as a by-product of the production process, emittedby firms. Each of the three water components is treated as a separateinput and all are estimated as a system of simultaneous equations. Themodel is estimated on a sample of 51 industrial plants in the Girondedistrict observed from 1994 to 1996 using Seemingly Unrelated Regression(SUR) and Feasible Generalized Least Squares (FGLS). Results ofestimations show that industrial firms are sensitive to water priceinputs. Network water elasticity is estimated at –0.29. It variesfrom –0.10 to –0.79 according to the type of industryconsidered. Autonomous water price elasticity is not significant.Elasticity for treated water is evaluated at –1.42 at themean-sample and varies from –0.90 to –2.21 according to theindustry considered.     

Bandwagon mergers,international competitiveness,and government policy

This paper suggests that while the static welfare losses of merger predilections among Western firms may not be dramatic, they may lead to substantial dynamic losses when merger-prone firms need to compete with firms which instead focus on equipment investment and investments in R&D. It is suggested that such diverging investment priorities have been the real cause of the deteriorating competitiveness of many of the largest Western enterprises vis-à-vis their Japanese rivals. While mergers are generally taken to be determined by either efficiency or monopoly considerations, this paper argues that Western merger predilections are likely to be generated by a combination of imitative and defensive routines as well. That would make it difficult for firms to unilaterally break away from these competitiveness-threatening investments. If correct, this would imply that competition policies would need to be refocused. However, it is also suggested that the implications for international competitiveness should make merger questions a subject of industrial policies too. In that respect, the paper suggests some basic attitudinal changes.Earlier versions of this paper were presented at a Global Forum for Competition and Trade Policy conference in Vienna and at a EUNIP workshop at Åbo Akademi University, Finland.

经济转型期的产业断层危机

产业断层危机不同于一般经济周期,它产生于产业结构升级转换中的结构失衡,表现为中长期的结构错落和增长速度迟缓。根据引发的因素可以分为“康氏周期拐点型”、“泡沫经济引致型”、“货币危机引致型”和“产业升级转换型”等类型,中国目前正处于工业化中期阶段,产业结构正面临着向新兴技术和新兴产业转型阶段,到2005年前后,我国将面临产业结构大规模升级,届时由于现阶段的资源瓶颈、产业回补、出口压力、技术瓶颈、产业虚高度化和尤格拉周期因素,可能会发生较大的产业断层危机。     

重新重工业化与振兴老工业基地

由于多方面因素的决定,中国走了一条先重工业、后轻工业、再重工业的工业发展道路,现在正进入一个重新重工业化的阶段,带来了经济发展的新机遇.重新重工业化的契机和良好的工业基础决定了老工业基地的振兴是必要的,也是可能的.振兴老工业基地的重点,应是发展拥有比较优势的重工业;振兴老工业基地的关键是实施产业集群战略,发展重工业产业集群.     

加速城市建设应注意的几个问题

目前,我国城市化进程不断加快,城市数量增加,规模扩大,成效显著.但是,也必须清醒地看到,城市建设工作中的短期行为和浮躁之风相当严重,应当引起人们的高度重视.本文认为,城市规模扩张必须以产业支撑为前提,不能搞空壳城市;城市公共设施建设慎向民资伸手,不能滥用市场化手段;居民区搬迁改造应多些人文关怀,不能一拆了之;应遵循城市发展的客观规律,正确处理城市建设中的几个关系问题.     

中小企业产业集群与绿色物流战略发展研究

产业集群对中小企业和所在地区的发展提供了一定的发展环境。现代物流的迅速发展不仅推动了产业集群区经济的发展，而且对区域环境的保护和可持续性发展起到了一定的推动作用；认识产业集群区绿色物流，从政府和企业两个方面采取措施实施绿色物流，是中小企业可持续发展的保障之一。     

全球化背景下的湛江市域发展战略研究

全球化加速发展，对区域发展产生了深远影响，也引起了湛江市周边区域环境发生着变化，环北部湾经济圈的崛起、“大珠三角”和“泛珠三角”的建设、中国一东盟自由贸易区的建成以及西部大开发战略的实施。文章以此为背景，分析了湛江市的区域地位(包括区位条件、区域优势和区域地位)，对湛江市域发展战略进行了思考，提出战略目标和重点，主要在培育产业集群、构建区域创新系统、建立区域协调机制以及实施点轴带动的不平衡发展战略。     

全球化背景下以动态比较优势实现产业技术跨越

全球化背景下中国失去了采用传统保护手段来培育动态比较优势，而面对新的机遇和挑战，中国应立足于自身资源禀赋的比较优势，在某些产业的关键环节选择技术跨越来培育动态比较优势；并通过发展高新技术、加强对传统产业的技术改造和提高技术引进效果来有效实施技术跨越，在一定程度上占据国际分工制高点。     

国外产业结构调整及其启示

从全球产业结构调整的基本趋势来看,农业比重逐步下降,工业和制造业比重有升有降,服务业比重呈上升趋势。在世界各国纷纷加快产业结构调整步伐的背景下,中国产业结构调整的紧迫感越来越大。我国产业结构优化的基本目标是:通过将传统产业的改造和信息产业等高新技术产业的发展有机地结合起来,在加快我国工业化进程的同时,提高我国经济与社会发展的信息化程度,使我国整个产业结构不仅实现不同产业部门之间的比例关系的协调,更重要的是推动产业结构的质的变化,即从低级化状态向高级化状态转变。而促进产业结构的转型和升级,客观上离不开政府财政的支持。
