Technical efficiency of UK airports

In this paper, the random stochastic frontier model is used to estimate the technical efficiency of UK airports. The airports are ranked according to their productivity for the period 2000–2005 and homogenous and heterogeneous variables in the cost function are disentangled. These changes the ranking of the efficiency of UK airports compared to more conventional measures.     

Regulating prices for shifting between service providers

The price that a regulated access provider charges for shifting customers between service providers has significant welfare implications. Typical regulatory approaches to pricing, such as pricing based on fully allocated cost or incremental cost, ignore the characteristics of consumer demand. A theoretical alternative, Ramsey pricing, considers only the elasticity of demand for given products. This paper directs attention to the competitive process. Using US long-distance telephone services as an example, this paper shows how empirical evidence concerning customer acquisition costs, customer switching costs, and churn among service providers can help to inform price regulation.

基于熵权TOPSIS模型的中国粮食安全评价研究

[目的]粮食安全事关经济健康发展、社会和谐稳定,是防范和化解系统性风险,维护国家安全的重要保障。对粮食安全发展水平进行评价研究是准确把握我国粮食安全发展现状、合理制定国家粮食安全相关政策措施的手段。[方法]随着我国进入新发展阶段,国家粮食安全被赋予新的时代内涵和新的发展目标。文章以我国粮食安全在新发展阶段所呈现出来的内涵和目标为导向,从供给能力、供给结构、绿色发展、经济效益以及基础支撑五个方面出发,构建了包括25个具体评价指标的粮食安全评价体系,并建立熵权TOPSIS模型对我国粮食安全发展水平的演变和现状进行评价研究。[结果]进入21世纪,我国粮食安全水平呈现出先下降后上升的发展态势,且对绿色发展、经济效益和基础支撑的重视程度逐年提升;提升我国粮食安全水平受到资源状况、科技水平、供给结构等因素的制约。[结论]保障和提升我国粮食安全水平,需要重点从耕地资源保护和利用、粮食科技支撑、国内外市场与资源整合等方面发力。     

Employment change in independent owner-managed high-technology firms in Great Britain

There is a growing volume of literature that points to the potential for small technology-based firms to achieve substantial employment growth. As a direct consequence of such work this sector of any economy has attracted increasing attention from national and local Governments concerned with finding ways of revitalising economically deprived localities and creating employment opportunities. This paper provides up-to-date empirical evidence surrounding the ability of small high-technology firms to create additional jobs in Great Britain. In addition, key founder and business characteristics are isolated which are significantly associated with employment change in growing high-technology firms over the 1986 to 1992 period. With respect to factors influencing these high levels of employment growth, a high firm size (in 1986) was found to act positively on employment growth, as was a graduate level education for the key founder. On the finance side firms which had access to and used a multiplicity of sources of start-up finance tended to grow faster. Futher, on the basis of our results we would suggest (and recommend) a Government policy which at the firm level actively encourages high-technology firm start-ups (who record higher rates of survival than firms in more conventional sectors) as well as providing support for existing high-technology firms who have already demonstrated the inclination and ability to grow in employment size.     

发展高端生产性服务业实现经济转型与后发赶超

现阶段,我国已迈入工业化的中后期,支柱型产业也已初具规模。所存在的主要问题是生产性服务业内部结构不合理,部分高端生产性服务业发展较慢,高端生产性服务业资金投入不足,人才缺乏。技术研发仍然以模仿为主,产业结构附加价值低,位于“微笑曲线”的底部。我国应积极发展高端生产性服务业,加快实现经济转型的步伐。在信息服务业和商务服务业方面,要积极承接国际服务外包,促进信息服务和商务服务的迅速发展,加快与国际接轨;在金融业与科技服务业方面,需要更注重集聚区效应。同时,要注重产学研相结合,加强与高校及科研机构的联合,强化集聚效应,拉动相关生产性服务业的发展。
