从需求角度出发,区分了节能环保产业中三种不同类型的市场,然后以SCP模型为分析框架,对三种不同类型的市场结构、企业行为和绩效进行了分析和比较,归纳了节能环保产业中不同类型的市场所存在的问题和解决思路。     

改造集散市场 建设新型再生资源回收利用体系

目前“三位一体”（回收网点→分拣中心→集散市场）回收体系模式,因集散市场功能单一、产业链短,不能带动行业走向产业化。回收网点建设适应我国国情,而集散市场成为先进的完整的回收体系的短板。按照示范基地建设标准,把集散市场改造升级为拥有深加工利用产业链,拥有平台支撑优势,能够进行资源的规模化高值化利用的产业园区。把回收和利用两大产业板块融合一体,是再生资源产业化的发展方向。     

堇青石负载Pd和过渡金属氧化物催化剂的表征及其对CO的催化氧化活性

以堇青石蜂窝陶瓷(CC)为载体,采用浸渍法制备了堇青石负载Pd和过渡金属混合氧化物催化剂,记作Pd-M-Mn(M=Cu,Co,Fe,Ni)/CC。实验结果表明:Pd-Co-Mn/CC催化剂的催化活性最高;随着Pd负载量的增加,CO转化率提高;当Pd负载量为1.00%时,反应温度为150℃时CO转化率达到98%,200℃时CO转化率达到100%;在反应温度150℃条件下,Pd-Co-Mn/CC催化剂(Pd负载量1.00%)的CO转化率在前30h内小幅度下降,随后稳定在90%以上,反应100h后,催化剂表面颜色由黑色变为棕褐色。     

中国碳交易市场发展现状及对策分析

中国强制碳交易标的物的确定、排放权的分配、排放源的监测核查等制度设计尚不明晰,也未出台温室气体交易活动的相关管理办法,碳减排体系尚未真正确立。碳市场处于初建期、探索期。通过对碳交易活动的背景、实质、运行机制以及国内碳交易现状的分析,结合应对气候变化的国际进展和国内政策行动对中国碳交易市场发展对策进行了探讨。     

京、沪、穗口岸入境外国旅游市场特征对比研究

我国入境旅游市场长期呈现港澳台市场占80％以上,外国市场不足20％的“二八”结构,因此拓展入境旅游外国市场是我国旅游业发展的重要任务。北京、上海、广州三大口岸是我国入境旅游发展的“桥头堡”,也是其他省市入境旅游发展的“二手客源地”,在我国人境旅游业中占据着十分重要的地位。采用问卷调查法,以从京、沪、穗口岸入境的外国游客作为调查对象,对三大口岸间的外国市场进行对比分析,并将其作为整体与全国入境外国市场进行对比研究,以期为拓展全国和其他省市的入境旅游外国市场规模提供理论指导。结论为：①从三大口岸入境的外国市场具有各自的特征,但在年龄结构、职业结构和学历结构上具有一致性。②从不同口岸入境的外国市场具有不同的空间分布范围和扩散能力。③从三大口岸入境的外国市场特征对全国入境外国市场特征具有控制作用。

Assessment of the Enabling Rural Innovation (ERI) approach: Case studies from Malawi and Uganda

This paper presents lessons from applying an innovative action research approach for linking smallholder farmers to markets, in eastern and southern Africa. The Enabling Rural Innovation (ERI) approach aims to strengthen social organization and entrepreneurial capacity in rural communities. It focuses on fostering community‐based capacity for the inclusion of rural women and the poor in analyzing and accessing market opportunities. Using case studies from Malawi and Uganda the paper assesses the outcomes of ERI on rural communities with a focus on human capital, gender issues and investment in natural resource management. Results show that households are benefiting significantly from linkages to markets in terms of increasing household incomes, and accumulating assets. Skills in analyzing markets and in negotiating with traders have increased among smallholder farmers. The integration of gender in the approach has led to changes in gender decision making patterns at household and community level towards a more shared decision‐making process. The results however show a difference in skills between men and women, with women showing lower levels of skills acquisition. Farmer participatory research has increased investments in improved technologies such as fertilizer applications for soil fertility management.

中国转型期水环境治理中的政府责任研究

水环境问题已成为制约我国长期可持续发展的主要瓶颈.如何有效治理水环境问题已引起全社会的普遍关注.本文在全面分析水环境公共物品属性以及水环境问题的客观现实的基础上,论证了政府承担治理水环境责任的必要性.进而对现阶段政府承担的水环境治理责任进行研究,归纳出其环境治理责任主要有财政责任、制度责任、监管责任和社会整合责任.然后对水环境治理中政府责任存在的现实问题进行深入分析,揭示其问题主要表现为:责任主体边界模糊、责任分布以“行政”为主导、责任履行中“越位”与“缺位”并存、责任种类中重直接投入轻间接引导.最后,提出水环境治理中的政府责任应该在坚持财权与事权统一、政府主导与责任分担统一、制度设计、监管与实施合理分离、政府引导与社会参与相结合的原则基础上,按照分类、分项、分级来构建转型期水环境治理中政府的应然责任框架体系.     

THE FLOOD HAZARD AND DYNAMICS OF THE URBAN RESIDENTIAL LAND MARKET1

ABSTRACT: Literature on the flood hazard/residential land market relationship is full of contradictory findings, many of which are counter-intuitive to the belief that flooding has a negative impact on house prices. This research advances a conceptual framework through which these relationships might be re-examined. Based on the expected utility model, the theoretical framework integrates the economic notion of capitalization with spatial and temporal characteristics of the flood hazard. Four communities with different flood regimes are used to test the effect of flooding on the residential real estate market. Results show that, (1) there is an identifiable relationship between characteristics of the flood hazard and changes in house values; (2) the length of the recovery period is dependent on characteristics and expectations of flooding, attributes of the real estate market, and availability of capital to fuel recovery; and (3) dynamics of the urban market and spatial extent of the flood hazard influence these relationships. Further research is now necessary to examine these findings under different spatial, temporal, hydrological, and socio-economic conditions.
