绿色建筑经济激励政策分析

绿色建筑难以推广的原因是绿色建筑的经济外部性问题,而解决外部性问题的通常做法是政府干预。我们从经济学的角度,对经济激励政策的原理进行了分析,除此之外,还重点对绿色建筑的外部经济性和非绿色建筑的外部不经济性进行剖析,最后我们提出了一些促进绿色建筑产业发展的建议。     

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。     

厦门市绿地生态网络构建及优化策略

科学构建城市绿地生态网络，对区域生态安全、城 市可持续发展及生物多样性保护具有重要意义。基于AHP法 和GIS技术，定量分析厦门市自然生态本底，选取重要生态斑 块和廊道，采用最小费用路径法模拟潜在廊道，综合构建城 市绿地生态网络，并提出绿地生态网络优化策略。结果表明： 1)AHP法可整合区域生态、经济、人文和社会等资源，全面 客观评价现状生态斑块和廊道的重要程度；最小费用路径法可 根据生境分布特征科学模拟连通各斑块之间的潜在廊道；2)厦 门市西北部的生态基底适宜性、生态源地及廊道重要性、斑块 之间有效连通性均高于东北部及中部平原区；岛内斑块面积小 且分散，南北部存在断层现象，应适度增加踏脚石和连通廊 道；3)结合城市生态发展需求，提出构建“一片、一环、三 带、多廊道、多节点”的城市绿地生态网络。研究结果可为厦 门市绿地系统规划提供科学依据。     

公众参与城市绿色空间管理维护 ——以坦纳斯普瑞公园为例

“公众参与”广泛应用于以美国为代表的西方现代景观规划设计领域。随着社会的发展在美国等国相继出现“公众参与”城市绿色空间管理维护的趋势，人们逐渐意识到管理维护对城市绿色空间的重要性。以美国波特兰市坦纳斯普瑞公园为典型案例，通过实地调查、文献研究、访谈、归纳推理等研究方法，从公园建设背景、设计特色出发，回顾“公众参与”前管理维护的困境，阐述“朋友和伙伴”项目的发展历程、工作内容及成效，总结“公众参与”后期维护管理的意义，分析成功推行的原因。“公众参与”有助于解决目前中国城市公园管理维护面临的投入资金不足、游人素质偏低等问题，对未来城市公园管理工作的发展具有重要启示意义。     

中国国内生产总值与教育之间关系的实证分析

本文从柯布-道格拉斯生产函数入手,将劳动力按受教育程度划分为四类分别进行处理。主要就中国国内生产总值(GDP)与各等教育程度劳动力和投资之间关系进行单整和协整检验,并建立误差修正模型(ECM),然后在协整条件下对各等教育程度劳动力与GDP的长、短期关系进行分析。文章的实证结果将为我国有关部门的政策决策提供有力依据。     

A Stochastic Frontier Production Function with Flexible Risk Properties

This paper considers a stochastic frontier production function which has additive, heteroscedastic error structure. The model allows for negative or positive marginal production risks of inputs, as originally proposed by Just and Pope (1978). The technical efficiencies of individual firms in the sample are a function of the levels of the input variables in the stochastic frontier, in addition to the technical inefficiency effects. These are two features of the model which are not exhibited by the commonly used stochastic frontiers with multiplicative error structures.An empirical application is presented using cross-sectional data on Ethiopian peasant farmers. The null hypothesis of no technical inefficiencies of production among these farmers is accepted. Further, the flexible risk models do not fit the data on peasant farmers as well as the traditional stochastic frontier model with multiplicative error structure.

Pure joint production and international trade: a note

This paper applies the principles of the neo-Ricardian (or Sraffian)theory of international trade to certain joint production systems.It is shown that, in contrast with single-product systems, (i)there is not always a pattern of international specialisation,which would entail the increase of the real wage rate in botheconomies, and (ii) the ‘law of comparative advantage’has no general validity. Furthermore, not only the existenceof such a pattern of specialisation but also the validity ofthis law depend on the values of the variables of distributionof income. The analysis is wholly based on two of the numericalexamples formulated by Bidard in 1997, and further generalisedin an elementary way only when this is considered necessary.     

Embedded industrial production systems: Lessons from waste management in zinc production

To meet the sustainability challenge private companies must implement corporate strategies and adopt novel technologies. The technical and social embeddedness of industrial production systems, however, complicates these systems' transition towards sustainability. In the paper, mechanisms and conditions are reported for the development and implementation of waste management options in embedded industrial production systems. The focus is on the Dutch zinc production industry, which had to deal with a major waste problem; the generation of jarosite. The industry's options were to increase the jarosite waste storage capacity, to develop a jarosite treatment process or to switch to a zinc-ore of low-iron content whereby no jarosite waste would be generated anymore. Required conditions appeared to be a combination of technological capability and technical embedding and favourable economics. Case study research, however, revealed that adequate stakeholder management is crucial to address social pressure exerted and to obtain external acceptance for any transition strategy. Whilst appropriate, internal technological capabilities are important, effective interactions with and enrolment of various firm-external actors are crucial. In the case of zinc, access to the heterogeneous external actor network was critical for the development of the jarosite treatment solution direction. In conclusion, both the technical, organizational and social embedding of new technologies are crucial for successful implementation.
