The UK gas industry has undergone major changes since it was privatised in 1986 as a fully integrated monopoly. The most significant of these has occurred not as a result of the privatisation legislation but by the intervention of the ordinary competition authorities in support of an active industry regulator. While price capping continues to be used as the primary instrument for welfare protection against the still substantial monopolistic powers of the incumbent, new competition (which has been positively encouraged) has had the greater impact on prices and choice. Recently, however, the regulator has encouraged the use of auctions for the sale of storage capacity. This paper considers the merits of auctions and makes a tentative evaluation of their effectiveness. Further use of auctions is recommended but reserve prices are considered inappropriate where monopoly power still remains.  相似文献

基于中国本土化理论——复合基础观,以浙江大华技术股份有限公司(以下简称大华)为例,结合后发企业追赶需要考虑的重要情境即机会窗口,分析后发企业在追赶过程中,如何合理、灵活地采取复合式战略回应机会窗口,并利用机会窗口带来的发展机遇,实现从初始追赶到超越追赶再到行业前沿的追赶历程。研究发现,同一行业内不同机会窗口之间环环相扣、相互影响,某一机会窗口的出现也会触发其它机会窗口出现,进而引致整个行业机会窗口涌现;基于复合基础观视角,后发企业追赶路径的演变过程为:最初以技术模仿式创新为导向实现边缘赶超,继而以市场把握和扩张为导向实现商业模式创新,然后以全面协同创新为导向实现系统竞争力提升;后发企业通过实施复合式战略回应机会窗口的开启,能够帮助其更好地把握住发展机遇,实现追赶;与追赶路径演变相关联,随着企业内部资源与能力的积累,战略回应机制也相应地呈现为“被动回应—主动回应—引领拓展”的演变过程。  相似文献

ABSTRACT

In this paper a novel information model that can be used in Manufacturing Execution Systems is presented. The model is based on the fusion of ISA95, AML and OPC UA. ISA95 is used to define, unify and describe the details of a product and production technology. It also enables communication with ERP systems. The AML standard allows information about the production facilities to be presented. The OPC UA address space represents different parts of an information model while the OPC communication protocol enables it to be linked to actual production systems. The proposed concept is illustrated using an actual example of a production line for electronic devices.  相似文献

This article examines the price behavior of consumer goods in the strategically vital country of Pakistan. Results show that prices converge both temporally and spatially. A wage-adjusted Consumer Price Index shows that Pakistani cities have converging costs of living. Finally, a novel measure of cointegration ranks the most and least economically integrated cities. Divergence does not occur along provincial, linguistic, or ethnic boundaries.  相似文献

This article uses new data to analyze the impact on Southeast Asian urbanization of globalization and industrialization in the world economy's core countries between the 1870s and World War II. Dramatic falls in transport costs and free trade, enforced, if necessary, by colonial rule, combined to open vast frontier areas throughout Southeast Asia to global commerce and create a handful of large urban centres. These cities, through linking Southeast Asian primary commodity exporters to world markets, grew predominantly as part of the global economy. Our econometric analysis shows that measures of globalization — in particular industrial production in the world core and international transport costs — are much better predictors of the size of Southeast Asia's main cities than domestic factors such as total population, GDP per capita, land area or government expenditure.  相似文献

为了确认Windows7平台下ARP欺骗攻击的防御能力,利用arpfree命令行工具,模拟三种不同的ARP网络攻击,分析攻击结果及对Windows7的性能影响,并检测ARP防火墙在面对以上攻击时的防御能力。未安装防火墙的Windows7可以防御ARPRequest攻击,但三种攻击都会显著的占用带宽资源。Windows7在防火墙的支持下,可以防御三种攻击,只能发现并阻断ARPRequest攻击,两种攻击仍然会占用大量用户的带宽与CPU资源。  相似文献

The oldest industry in Australia subjected to economic regulation is the gas supply industry in the state of New South Wales. In this paper the aims and motivation of the New South Wales Government in establishing the regulatory regime in 1912 and the subsequent effectiveness in achieving them are determined. Initially the regulatory regime was based on ad hoc arrangements, but eventually a more permanent structure was devised that effectively defused political controversy over gas market pricing and stabilised prices rather than substantially lowered them.  相似文献
