中国生物质利用政策演变与展望

介绍了中国生物质利用政策的背景:保障能源安全,保护环境,促进经济社会可持续发展。阐述了中国生物质利用政策发展演变的四个阶段:早期的生物质利用政策、能源需求增长下的生物质利用政策、能源安全下的生物质利用政策、全球气候变化下的生物质利用政策。展望了中国生物质利用政策的发展前景和方向:非粮,非耕地,立足国内,并注重保护环境。     

The effects of exports on facility environmental performance: Evidence from a matching approach

This paper employs matching techniques to investigate the effects of facility export status on environmental performance. Using facility-level criteria air emission data in the US manufacturing industry, we find the industry-specific effects of export status on emission intensity, measured by emissions per value of sale. In some industries, there is consistent and robust evidence supporting the superior environmental performance of exporters relative to non-exporters in terms of emission intensity for all criteria air pollutants tracked. In other industries, we find weak evidence that exporters appear to have a higher emission intensity than non-exporters. This industrial heterogeneity in the effects of exporting on the environment is closely related to industrial characteristics including pollution abatement capital expenditure, trade costs, capital intensity and others.

基于产业集群理论的农业产业化经营对策分析

当前各地农业产业化发展带动了一定规模的产业集聚,但由于存在种种矛盾,集群效应并不明显。为此应充分发挥政府作用,构建产业集群发展平台;依托特色产业和生产基地,打造龙头企业;强化龙头企业与农户的利益连接机制;加强农业产业链上各经营主体的分工协作,形成地方网络;建立健全产业化服务体系,延长农业产业链等,以推动农业产业化的健康发展。

城市污泥脱水干化技术分析

城市污泥所含水分性质复杂,有间隙水、毛细水、结合水存在形式。污泥经浓缩、脱水后含固率仍很低,不能自持燃烧。而采用低压、水热预处理和离心式脱水机半干化处理后,可以提高污泥热值,降低运输和贮存成本,同时可以减少燃料和其他物料的消耗,是城市污泥干化可行的技术路线。     

新疆非税收入运行状况分析

伴随着新疆经济的快速发展和税收规模的扩大,非税收入也呈现出快速增长的趋势,非税收入在缓解新疆地方财政支出压力、公共品融资难等方面发挥了重要作用。但在现行财税体制框架下,新疆非税收入运行中还存在诸多深层次的问题,其对外部性的校正及对经济的调节功能尚没有充分发挥。本文通过对新疆非税收入运行状况以及存在的问题和影响因素进行分析,进而提出了进一步完善非税收入管理的政策建议。

Tourist experience of nature in contemporary China: a cultural divergence approach

The study of Chinese nature tourism is a relatively independent research realm which adopts a cultural perspective to study the tourist experience. Chinese tourists are regarded as being accustomed to experiencing nature through associating it with high culture such as landscape poetry and paintings, calligraphy, and so on, and the impacts of traditional popular culture are seldom addressed. Yet, for the majority of Chinese, popular culture has significant influences on their behavior. From a cultural divergence approach, this paper chooses Huangshan Mountain as a case to investigate the way common Chinese people experience nature, and it is found that cultural impacts are differentiated, since neither cultures nor tourist groups are homogeneous. Specifically, tourists can be classified into classicists and folklorists according to whether they have professional knowledge about the traditional arts. As the majority of Chinese are folklorists and are largely neglected in the research, they are the main interest of this study. High culture has a weak impact on folklorists because they lack professional knowledge to associate with nature through high culture. It is popular culture that strongly influences folklorists’ behaviors in their drawing farfetched analogies to nature and praying to nature.     

我国刑事错案与刑事犯罪关系之分析——基于空间计量经济学分析方法

依据31个省域数据,采用纳入空间效应的计量经济学模型,研究刑事错案与刑事犯罪之间的关系,结果发现:我国刑事错案与刑事犯罪在地理空间上并不是完全随机分布,而是具有显著的空间依赖性,呈现较为明显的空间聚集效应；省域间的空间相关性在提高刑事案件审判质效、降低刑事犯罪率的分析和政策制定过程中发挥着重要作用；刑事错案率对刑事犯罪率具有明显的正向促进作用.
