开发区是全球化时代出现的新产业空间。开发区在我国经济发展和改革开放中,发挥了重要作用。理论界将我国开发区发展阶段总结为一次创业和二次创业两个阶段,但是目前我国开发区普遍出现了从工业园向新城区转型的趋向。从企业家型城市的理论视角,通过对苏州工业园发展与转型的实证研究,论证开发区建设进入第三次创业的新阶段———即从工业园向城市新区的转变。在新一轮转型中,苏州工业园实施了企业家的城市策略,采取了园区再定位、创造新城市空间等企业家城市行动,园区的新城功能和第三产业得到迅速发展。同时,研究也发现园区管委会的管治体系发生了根本变化,从促进经济增长管理向社会和城市综合管理转型。该研究将对我国新一轮开发区的转型具有重要启示。 相似文献

曹妃甸工业区水资源承载能力研究 总被引:1,自引:0,他引:1
根据曹妃甸地区地表水和地下水资源异常紧缺、降水量不足、主要依靠跨区域调水的特点,综合考虑环境、人口、社会、经济等各方面要素,选取水资源子系统、生态环境子系统和社会经济发展子系统,并运用区域水资源规划管理理论,采用多目标规划技术建立了水资源承载力的多目标评价模型;结合按照各种发展模式设定的A,B,C,D四种情景,采用隶属度的方法分析计算了曹妃甸工业区2010,2020,2030年在A,B,C,D四种不同发展情景下的水资源承载力,得出A,B发展模式下曹妃甸工业区水资源准不可承载,C,D发展模式下可承载的模型预测结果;并针对评价结果,结合工业区实际情况,提出曹妃甸工业区提高水资源承载力的对策. 相似文献

In 2006, the British Standards Institute (BSI) published BS 8887-1 ‘Design for Manufacture, Assembly, Disassembly and End-of-life processing’ (MADE) subtitled ‘General Concepts, Processes and Requirements’. This was the first British Standard to address design for efficient post-consumer product reprocessing. By designing and planning for remanufacture, much of the embodied energy and production investment can be retrieved after the consumer no longer requires the original item. Therefore, end-of-life products become an asset rather than a liability. Design for disassembly facilitates efficient deconstruction and thus enables materials to be recycled with minimal loss of purity, thus maximising their value. The analysis presented here is based on the Standard Industrial Classification codes of companies and organisations that have purchased BS 8887-1. These data are considered in relation to the influence of environmental legislation. Company age, size and location, as well as ISO 9001 and ISO 14001 certifications, are discussed. This paper concludes by suggesting suitable directions for the continued distribution and development of this environmentally, economically and socially beneficial standard. 相似文献

Industrial ecology: a review 总被引:7,自引:1,他引:6
F. den Hond 《Regional Environmental Change》2000,1(2):60-69
Industrial ecology is both a vision, a research field, and a source of inspiration for practical work. Its proponents aim
to contribute to sustainable development by closing materials cycles and realising a fundamental paradigm shift in the thinking
concerning industry–ecology relations. Dominant research lines in industrial ecology focus on industrial metabolism and life
cycle tools. The underlying assumption is that the flow and transformation of materials can be managed through the correcting
of market and regulatory failures which are causes of environmental degradation. This literature review suggests, on the one
hand, that the manageability of the flow of materials is currently limited by market and regulatory failures which inhibit
the implementation of the principles of industrial ecology and, on the other hand, that the flow and transformation of materials
are only partly affected by prices, information and laws.

AbstractIndustrial Ecology hypothesises that networks of industries designed to be analogous to the structure and properties of food webs may approach a similarly sustainable and efficient state. Although ecology is the metaphor for designing Eco-Industrial Parks (EIPs), prior research has shown that EIPs are inferior in performance compared to natural ecosystems. One EIP design approach is to enlarge EIPs by combining two or more synergistic networks to create a larger, and hopefully more successful, synergistic mega-network. A quantitative analysis using structural ecosystem metrics is presented in this paper in order to test the potential of this approach. The findings indicate that merely enlarging EIPs by significant amounts may not be the best strategy for improving performance, but that special attention should be placed on the inclusion of key actors like agriculture that act like detritivores and promote more intense internal cycling. 相似文献

In recent years, pyrolysis processes have become technologies developed to industrial scale and discussed as alternatives to the existing waste combustion technology. However, little information is published regarding PCDD/F formation characteristics during pyrolysis processes. Two common shredder fractions – industrial light shredder (ILS) and refrigerators (REF) – both with high chlorine and copper content were pyrolysed for this pyrolysis study using a pilot plant with a capacity of 100 kg/h. At oxygen concentrations below 2% and temperatures between 430°C and 470°C, considerable amounts of PCDD/F were formed during the pyrolysis. More than 90% of total TEQ was found in the oil fraction (gas phase). The PCDD/PCDF ratio and the homologue pattern differed significantly from those formed during waste incineration. Considering mono- to octachlorinated congeners, up to 400 times more PCDF were formed compared to PCDD. For the investigated pyrolysis conditions, the formation of low chlorinated congeners was highly favoured. The distribution of TEQ within the individual congeners were very similar in all investigated runs. More than 80% of total TEQ stem from 2,3,7,8-substituted T4CDF and P5CDF. The isomer pattern, however, did not show significant differences compared to the common waste incineration pattern suggesting that the basic formation routes are similar. 相似文献

With the rapid development of foreign trade in China, industrial import and export has been an absolute subject in recent years. The huge trade surplus of import and export trade of industrial products brings not only high profits, but also pollution costs as well. Based on the concept of water pollution footprints (WPFs), this study applies the input-output method and calculates pollutant-producing coefficients of 20 major industrial sectors in China and investigates the WPFs caused by the import and export trades of these industrial sectors. The research results show that WPF resulting from exports exceeds that of imports from 2011 to 2015 in China. The net inflow of pollution footprint is mainly from paper mills, printing and stationery manufacturing, and textile industry; whereas a great number of WPFs are transferred to other countries by these sectors, such as metal mining and dressing industry and oil and natural gas exploitation industry. 相似文献
