中国碳交易政策的减排效应及其机制研究

全球气候变暖对环境和经济发展影响巨大,碳排放是气候变暖的主要原因,碳交易政策是基于市场机制控制碳排放及推动绿色低碳发展的一项核心政策工具。采用2004—2019年中国30个省的面板数据（因数据缺失,未包含西藏地区和港澳台地区数据）,基于双重差分和中介效应模型对碳交易政策的减排效应及其作用机制进行了实证研究。研究结果表明,不论从总体看还是分区域看,碳交易政策均具有显著的减排效应,但效应的大小存在区域差异,碳交易政策在东部地区的减排效应比中西部地区更大。机制分析发现,碳交易政策可通过减少能源消耗规模、促进技术创新、促进产业结构升级、增加外商直接投资等渠道实现减排,能源规模、技术创新、产业结构、外商投资等在碳交易政策传导中具有显著的中介效应,但这种传导机制存在区域差异。

Customer loyalty to newly opened cafés and restaurants in Malaysia

An extended review of the literature indicates that there is an insufficient number of past studies which test the SERVQUAL model (tangibles, reliability, responsiveness, assurance, empathy) in the food and beverage industry. Therefore, this research attempts to provide new insight into the impact of service quality on customer loyalty in the food and beverage industry. The purpose of the research is to determine the impact of service quality and price fairness on customer loyalty in the food and beverage industry in Penang, Malaysia. This article surveyed the customers of newly opened cafés and restaurants in Penang, Malaysia, by using a structured questionnaire. The research revealed that service quality (tangibles, reliability, assurance, and empathy) and price fairness have a positive relationship with customer loyalty. However, responsiveness had no relationship with customer loyalty. This article includes an additional independent variable, price fairness, to investigate customer loyalty.     

Estimating the impact of investing in a resource efficient,resilient global energy-intensive manufacturing industry

To examine the prospects of creating a resource efficient, low-carbon economy, this paper focuses on the impacts of investing in energy, water and waste. The broader industrial sector, as well as six energy-intensive manufacturing industries is studied. A system dynamics model is developed for each selected sub-sector, which is embedded in a broader integrated framework to fully appreciate the linkages within the industries and across the economy, environment and society. This study further simulates and analyzes the key factors affecting the economic performance and environmental impacts of these industries in a resource efficient scenario compared to a business-as-usual (BAU) case. Our analysis indicates that with no additional resource-efficiency and conservation actions taken, these industries – highly exposed to rising fuel prices under BAU – will suffer from declined profitability over time. Under the alternative scenario however, an incremental investment in efficiency will not only substantially curb energy demand and emissions, but will also effectively reduce energy expenditures in all analyzed industries yielding an overall positive return on investment after nine years. Though the extent of cost saving varies across the sub-sectors due to the variation in energy mix, they will all see considerable reduction in unit production costs and increase in operating margins and profits in the medium to longer term.     

湖南优势农产品生产县域布局优化研究

农产品比较优势是优化区域农业生产布局的重要依据。文章以湖南省122个县市区为研究单元,选择稻谷、油菜籽、蔬菜、茶叶、柑橘、烟叶、生猪、水产品8种优势农产品,运用主成分分析法,借助DPS数据处理系统,对各县市区2009、2014年优势农产品生产情况进行了排序和分类,研究了区域分布演变情况。结果表明:(1)湖南优势农产品生产各县域间总产、不同种类、不同时期存在明显差异;(2)"十二五"与"十一五"相比,优势区域重心向洞庭湖、湘南地区集中,非优势区域向大湘西、长株潭地区扩散;(3)优势类县市区重点集中在常德、益阳、岳阳、衡阳、永州、长沙6市,次优势类县市区主要分布在湘西、邵阳、怀化、永州、郴州、岳阳6市(州),非优势类县市区主要分布在株洲、长沙、湘潭、郴州、衡阳、永州、邵阳、湘西8市(州)的城区和偏远山区。(4)2014年与优势类、次优势类、非优势类县市区综合得分关联序最大的4个评价指标分别依次为油菜籽、水产品、稻谷、茶叶,生猪、稻谷、蔬菜、水产品,稻谷、生猪、蔬菜、柑橘。提出了湖南优势农产品生产应提升优势类、巩固次优势类、转型非优势类的县域布局优化对策。

“不似之似”管窥中国舞蹈的意境——兼从文学和美学的角度

舞蹈意境的特征 ,在于人体动作在舞台空间和时间当中创造出来的意象 ,这意象是具体的、真实的 ,却又是虚拟的、象征的 ,这和中国画的“不似之似”有共同特点。本文从舞蹈意境“不似之似”的审美特征入手 ,并结合文学与美学内容 ,对中国舞蹈意境的创造作一点粗陋探索。     

对高职计算机基础教学模式的改革探讨

在高职教育发展过程中,传统的教学模式和结构已不适应目前高职人才培养的需求。特别对于计算机这种实践性较强的课程,教学内容和知识结构的应用性、实践性、创新性以及知识更新已跟不上新技术的发展和变化。如何搞好计算机基础教学,培养学生的创新精神和实践能力,已成为目前高职院校进行计算机基础教学模式改革的重要内容。     

金融危机对广东农业经济的影响及对策

本文分析了目前全球金融危机对于广东省经济发展造成的影响,探讨了金融危机对广东农业经济发展可能带来的潜在危害,认为,金融危机的演化将会显著降低农民的经济收入、影响土地流转政策的有效实施、威胁广东农村及整个社会的政治稳定及和谐发展。因此,政府有关部门应实施财税支持政策,扶持中小企业发展;同时应加强中小企业生产的监管,防止恶意性破产;并积极鼓励返乡农民工自主创业;加大对返乡农民工的技能培训,从而有效化解金融危机的危害。
