生态环境监测与生态经济学评价

探讨了荒漠生态环境监测与生态经济学之间的关系,提出荒漠生态环境监测应与生态经济学原则相结合,注意监测人类社会经济活动对生态环境的影响,并根据生态经济学中环境因素的稀缺性、综合性和反馈性等原理对人类开发利用自然资源进行正确评价。     

经济新常态下外贸发展对我国碳排放的影响

选取灵活的单区域模型,运用实物产值比计算方法,选取日本为进口代表国并结合进口国GDP排放强度的修正方法,针对加工贸易产品占我国外贸总额约50%的特点,改进现有内涵排放测算方法.研究结果显示我国出口产品内涵排放得到了显著的改善,呈现碳排放与出口额脱钩的现象,进口产品内涵排放占比全国碳排放的比重维持在3～5%左右,“十二五”期间净出口内涵排放的总量和占比比“十一五”期间都有所降低,显示我国出口贸易政策调整作用正在显现.需要不断坚持优化进出口政策,尽早实现我国进出口产品内涵排放之间的平衡.投资增速的快速下降已经开始对产业结构产生影响,但中国未来需要进一步加速最终消费的增长以弥补投资下降所带来的需求不足,并鼓励服务业需求的发展.     

Circular business models: Babbling initial exploratory

This research aims to map Brazilian companies that have business models aligned with the concept of the circular economy. Data were collected for this study through use of a survey and additional research based on the survey results. Within these businesses’ models, an emphasis on the second use of materials as well as the marketing of the product as a service has been highlighted.     

泰州市环境质量与经济的库茨涅兹曲线模拟研究

“环境库茨涅兹曲线”是指经济发展与环境质量之间的“倒U型”曲线关系,即随着经济发展和收入水平的提高,环境质量先恶化后好转。全文基于环境库茨涅兹曲线特征原理,根据泰州市2006年-2015年经济与环境变化的状况,重点分析了泰州市化学需氧量排放量、地表水中高锰酸盐指数、大气污染物二氧化硫排放量、二氧化硫浓度各指标与泰州市经济发展之间的拟合最佳模型。结果表明,前三者与人均GDP的变化规律符合环境库兹涅茨假设。空气中二氧化硫浓度对人均GDP之间的变化规律虽不符合环境库兹涅茨假设,但空气中二氧化硫浓度将呈下降趋势。     

Open workshops as sites of innovative socio-economic practices: approaching urban post-growth by assemblage theory

ABSTRACT

Current debates on knowledge-based and creative locational development have come to deal with small urban places of novelty that formerly remained unnoticed. A plethora of new forms of producing and working recently emerged in unplanned and uncoordinated ways, bearing odd names such as FabLabs, Open Worklabs, RealLabs, Open Design Cities, Techshops, Repair Cafés, and more (Smith, A., M. Fressoli, D. Abrol, E. Arond, and A. Ely. 2017. Grassroots Innovation Movements. London: Routledge). Political initiatives have been taken by surprise; at the same time, standard epistemic tools of the social sciences and economics have been rendered unfit. More concise analytical reconstructions are needed to adequately capture the variety and complexity of these “labs”, their heterogeneous causation, their contingent proceedings, their surplus of latency, their peculiar power relations and their local embeddings. Urban social contexts have a strong triggering function as they help to re-configure older, and create new, combinations of heterogeneous social and economic agency. Meanwhile strong elements of grassroots innovation (Smith et al. 2017) have informed the formation of various models of alternative work and production. Taking the phenotype of open workshops as a revealing example, we take assemblage theory to describe the constitutive features of these new types of self-organised work, and the associated places of innovation. A fresh gaze on the complexity and open-endedness of socio-material formations may help to better understand the nature of emerging post-growth economies.     

Emerging drivers and business models for equipment reuse and remanufacturing in the US: lessons from the biotech industry

While regulations have advanced product take-back in some markets, challenges to increasing product reuse and remanufacturing remain. Most research to date has focused on original equipment manufacturers taking back and remanufacturing their products, which is often problematic. The present study demonstrates that there are emerging opportunities for small companies with innovative business models to enter the market and advance product end-of-life (EoL) management. The paper examines the biotechnology industry – a growing sector with high spending on lab equipment and relatively short lifespans of research and development instruments. Building on previous research and analysis of industry practices and emerging drivers for product reuse and remanufacturing, the authors propose a framework for sustainable EoL management that includes five managerial drivers: financial benefits, space, ease/convenience, information, and sustainability goals. The paper concludes with discussion of the lessons learned and practical implications for managers in charge of purchasing or disposing of surplus equipment.

经济系统物质流分析研究述评

经济系统物质流分析方法近年来在可持续发展研究领域发展尤为迅速。论文对该研究方法的发展历程、主要观点、逻辑框架及相关应用研究进行了评介,并在此基础上指出了其方法的主要作用和局限,对其未来研究的发展方向提出了建议:①主要作用有二,一是能够得到简洁的可持续发展示踪指标,二是得到的采用物理量为单位的物质流指标便于比较;②主要局限有三,一是大的物质流会冲淡物质流指标描述物质流动状况的清晰度,二是物质流指标与物质流动环境影响之间的联系不够紧密,三是使用范围有限制;③未来研究发展方向有三,一是挖掘物质流分析结果所蕴含的社会研究价值,二是与土地利用分析的结合,三是向物质投入产出表的迈进。
