The paper examines characteristics of science parks in the face of employment decline, raising doubts about the scale of their success. The paper re‐examines previous research on the existence and causes of long waves of economic growth and decline and concludes that if these are not generated by innovations in production, then it should not be surprising that science parks have not lived up to expectations. 相似文献

The computer and telecommunications technology has created new opportunities for developing interaction between offices and enterprises located far away from each other. Even if the market forces favour concentration to R & D centres in the big cities and in university towns, there are expectations that the distance over‐bridging qualities of the new technology can create development opportunities for sparsely populated peripheral areas. In this paper the interplay between the new technology and other important factors in the local and regional environment are discussed with the focus on both opportunities and restrictions. 相似文献

There has been a marked proliferation of local economic development initiatives in recent years. Enterprise Boards have proved one of the most successful of these innovations. In the early 1980s five were established. Two, the Greater London and the West Midlands Enterprise Boards, were initially designed to intervene radically within their local economies, although subsequent events moderated their activities. The remaining three in Lancashire, West Yorkshire and Merseyside, have successfully widened their operations to embrace collaborate projects with the private sector, training, boosting co‐operatives, and research. By many economic evaluations, for example, jobs supported, leverage ratios and investment per job, Enterprise Boards have performed better than other instruments of urban and regional development. Wider socio‐political objectives have proved more difficult to achieve. 相似文献

The paper examines changing approaches to local economic development in the period since 1974. Initially, it proposes an ‘orthodox’ model of local economic development policies which emphasised the provision of a better industrial fabric, and of financial assistance to small, inner city firms. It suggests three recent directions of change in emphasis from this orthodox model: help in the creation of new entrepreneurs; replacement of public sector by private sector action; local authority shareholding in local firms by use of Enterprise Boards. Each approach makes different assumptions about the public/private sector relationship, the last two involve a more explicitly ideological stance on this issue. 相似文献

In this study, we analyzed the sustainability and determinant factors of waste reduction through variable charging schemes.
We drew three main conclusions from the study. (1) Waste reduction was achieved by variable charging and was sustained over
an average of at least 10 years. The results regarding the sustainability of the price effect were inconclusive. (2) The main
factors contributing to the combustible waste reduction achieved through variable charging were two-tier pricing and the price
of waste bags. The effect of two-tier pricing programs was positive. (3) Waste paper recycling and variable charging reinforce
each other to promote waste reduction.

A national Baumol–Oates tax on waste in Denmark helped achieve a reduction of 26% in net solid waste from 1987 to 1998. The
tax, which is levied per ton of waste, was particularly effective as regards the heavier waste streams such as construction
waste and garden waste. When it comes to industrial and commercial waste, there are indications that the waste tax is not
sufficiently significant to induce changes in behavior, and that except for very waste-intensive enterprises, companies do
not seem to be very price sensitive. For household waste, the impact of the tax can be improved where tariffs for garbage
collection are weight based, rather than per unit. However, the waste sector is an area in which the price signals are modified
and filtered by institutionalized practices in municipal administration, and in which true-cost pricing is not easy to achieve.
Hence, the rational choice assumption of environmental economics needs to be supplemented by an institutional dimension to
interpret responses to environmental taxes correctly.

马克思、思格斯早在19世纪40年代已经前瞻性地论述了经济全球化的思想,他们认为:资产阶级的资本是经济全球化的主体和内在动力,经济全球化的实质是资本的全球化;经济全球化的原因是生产力的发展和技术的进步;经济全球化的趋势是全球社会主义。马克思主义的经济全球化理论为研究当代经济全球化的原因、特征、发展趋势及其对当今世界的影响有着重要意义。 相似文献

Relative to manufacturing, service activities are often considered by planners and officials to generate considerably less environmental pollution. This hypothesis is tested by means of an examination of the economic linkages of both manufacturing and service activities and of the resulting direct and indirect emissions of five air pollutants per dollar of output in the California statewide air basin and in four regional basins within the state. Overall acceptance or rejection of the hypothesis depends in part on the particular pollutant and air basin considered but, most importantly, on the judgement as to what activities are to be considered as service activities.This paper is based on research sponsored by the California Air Resources Board under Agreement A7-143-30. 相似文献

The empirical evidence of decline in ecosystem services (ES) over the last century has reinforced the call for ES quantification, monitoring and valuation. Usually, only provisioning ES are marketable and accounted for, whereas regulating, supporting and cultural ES are typically non-marketable and overlooked in connection with land-use or management decisions. The objective of this study was to quantify and value total ES (marketable and non-marketable) of diverse production systems and management intensities in Denmark to provide a basis for decisions based on economic values. The production systems were conventional wheat (Cwheat), a combined food and energy (CFE) production system and beech forest. Marketable (provisioning ES) and non-marketable ES (supporting, regulating and cultural) ES were quantified by dedicated on-site field measurements supplemented by literature data. The value of total ES was highest in CFE (US$ 3142 ha−1 yr−1) followed by Cwheat (US$ 2767 ha−1 yr−1) and beech forest (US$ 2328 ha−1 yr−1). As the production system shifted from Cwheat - CFE–beech, the marketable ES share decreased from 88% to 75% in CFE and 55% in beech whereas the non-marketable ES share increased to 12%, 25% and 45% of total ES in Cwheat, CFE and beech respectively, demonstrating production system and management effects on ES values. Total ES valuation, disintegrated into marketable and non-marketable share is a potential way forward to value ES and ‘tune’ our production systems for enhanced ES provision. Such monetary valuation can be used by policy makers and land managers as a tool to assess ES value and monitor the sustained flow of ES. The application of ES-based valuation for land management can enhance ES provision for maintaining the productive capacity of the land without depending on the external fossil-based fertilizer and chemical input. 相似文献
