开放经济视野下广东与越南的合作与互鉴

随着“中国一东盟自贸区”建设的加速推进,广东与东盟合作,尤其是与越南经济合作面临十分难得的机遇。越南作为东盟重要成员、重要合作对象的位置日益明朗。由于在经济发展模式上广东与越南非常相似,因此后危机时代广东面临的挑战也许将是越南明天面临的挑战。广东正在进行战略转型升级,表现为对加工贸易进行“转方式、调结构”、进行技术创新、提高利用外资水平、推进市场多元化、建立风险机制等,这些经验可供越南参考。     

减排框架下的排污权交易机制及其配套政策研究

本文通过建立数学模型,考察了减排框架下的原有企业、新进入企业和地方政府之间的排污权交易机制及其配套政策。首先分析原有企业,得到结论如下：第一,环境税对原有企业最佳排污量选择的影响是不确定的,原有企业最佳排污量选择随着排污权出售价格的上升而下降。第二,在排污权可以跨期交易的条件下,原有企业持有稀缺排污权符合利润最大化选择。其次研究了在排污权跨期交易机制下,新进入企业购买排污权的价格持续增加,这样将导致新进入企业进入成本不断提升。最后分析认为减排政策有助于提高区域经济福利。在此基础上,提出活跃排污权交易机制及其配套政策的建议。     

Branding in a global marketplace: The mediating effects of quality and self-identity brand signals

Research documents that consumers with a stronger belief in global citizenship through global brands (GCGB) view branded products as more important and prefer global to local brands. We test the mediating effects of consumer use of quality and self-identity brand signals on the relationships between GCGB and the importance attributed to branded products (Study 1: U.S. and Russia) as well as purchases of global brands (Study 2: U.S., U.K, and Russia). Our research establishes that consumer involvement with branded products and purchases of global brands revolves around consumers' use of brands as signals of quality and self-identity. In the developing country, results document mediation effects for the use of both quality and self-identity signals on the importance of branded products and global brand purchases. In developed countries, we find that the importance of branded products is explained by a greater use of brands as self-identity signals, whereas purchases of global brands are explained by a greater use of quality signals. Overall, consumers with a stronger belief in GCGB are more likely to use brands as symbolic signals and to express their identity through brands, and consumer use of global brands as quality signals provides a distinct competitive advantage to global brands in both developed and developing countries.     

2011年中国成品油市场半年回顾及展望

2011年上半年,我国三大类成品油（汽油、煤油、柴油）表观消费量达到1.27亿吨,同比增长8.1%,较2010年全年增速放缓3.7个百分点。其中,柴油消费量为8089万吨,同比增长8%;汽油消费量为3744万吨,同比增长8.3%;煤油消费量为845万吨,同比增长8.4%。成品油消费增速稳中趋缓,这既与经济增长、部分刺激政策退出和货币政策收紧有关,又与主要用油行业的运行特点密切相关。上半年原油加工量和成品油产量同步增长,成品油产量增速与消费量增速相当,供需基本平衡。下半年,世界经济平稳复苏面临的风险增多,国内经济将稳中趋降,汽车、房地产两大消费支柱产业难有明显起色,成品油需求增长将显著回落。预计下半年我国成品油表观消费量为1.36亿吨,同比增长5%,增速较上半年下降3个百分点;成品油产量约为1.35亿吨,与市场需求量基本相当,全国成品油市场将保持供需基本平衡的态势。

熵权灰色关联下鄱阳湖生态经济区产业发展研究

选取相关指标,采用熵权灰色关联模型评价鄱阳湖生态经济区六市的三大产业。结果表明:南昌、九江的三大产业发展比较均衡,整体水平处第一层次;景德镇、鹰潭、抚州、新余四市除抚州在第一产业得分最高之外,其他得分都比较接近,与南昌、九江存在较大的差距。故应积极提升南昌、九江的核心竞争力,发挥其区域中心城市的作用,带动整个鄱阳湖生态经济区快速发展;同时景德镇、鹰潭、抚州、新余四市应依托现有的优势资源,发展特色产业。     

基于熵权的地铁施工对邻近建筑物的风险模糊评价

结合地铁施工的特点,分析地层位移对邻近建筑物的损害形式,明确地铁施工引起地层位移对邻近建筑物安全影响的主要风险源,从而建立相应的评价指标体系;采用熵权法和模糊综合评判相结合的综合评价方法,建立风险评价模型;最后进行实证研究,结果表明具有较强的可靠性。     

Entrepreneurship and asymmetric information in input markets

Entrepreneurs starting new firms face two sorts of asymmetric information problems. Information about the quality of new investments may be private, leading to adverse selection in credit markets, and entrepreneurs may not observe the quality of workers applying for jobs, resulting in adverse selection in labor markets. We construct a simple model to illustrate some consequences of new firms facing both sorts of asymmetric information. The market equilibrium can involve an excess supply of workers entering the entrepreneurial sector, as well as credit rationing. Equilibrium outcomes mismatch workers to firms, and will generally result in an inefficient number of both entrepreneurs and workers opting for the entrepreneurial sector. Taxes or subsidies on new firms and on wages can improve efficiency, but a second-best optimum can only be achieved if it is optimal to induce an excess supply of workers to enter the entrepreneurial sector.
