中国商业银行竞争力及影响因素分析:2002—2009年

本文选取中国14家上市商业银行作为研究对象,利用2002—2009年的数据,通过定义社会生产效率、服务效率、盈利效率和成长效率,研究中国银行业的整体效率、效率值动态变化和各银行的效率情况。结果表明,四大国有控股商业银行与一般股份制银行和城市商业银行相比,其社会生产效率、盈利效率过低,但如果将投入变量中的员工数目换为工资薪酬,国有控股商业银行的效率则有很大提升;股权结构会影响效率值,但国有股与效率值不一定负相关,而外资股和效率值正相关,只对于生产效率成立,对于服务效率和盈利效率刚好相反。     

中国区域生态效率测度与差异性分析

生态效率是区域可持续发展的重要测度指标,反映了区域经济发展有效应用资源减轻环境压力的效率。尝试将超效率DEA方法应用到生态效率测度中,对中国2000—2009年区域生态效率展开评估,并据此进行各区域类型划分,进而从全国及东中西三大经济带视角研究区域生态效率的差异性。研究发现：在此期间中国整体生态效率呈稳定上升趋势,但生态效率差异明显且有增大趋势,各区域生态效率同其经济发展水平密切相关,东中西三大经济带生态效率演化规律各异,东部地区生态效率提升动力强劲但内部各省份差异呈现增大趋势,中西部地区生态效率提升动力不足且其内部省份差异趋稳。     

我国外商投资企业转移定价避税应对策略

根据跨国公司转移定价避税与东道国税务机关反避税调查博弈分析的结论,在新《企业所得税法》实施的环境下,我国有效应对外商投资企业转移定价避税的措施是:提高避税的处罚率,加大对外商投资企业滥用转移定价避税的处罚力度;通过完善税务操作规程与细则,增大外商投资企业利用转移定价避税的成本;推广预约定价制度,严格控制税务机关对转移定价进行反避税的调查成本。

Biofuel policies and the environment: Do climate benefits warrant increased production from biofuel feedstocks?

We examine whether climate benefits warrant policies promoting biofuel production from agricultural crops when other environmental impacts are accounted for. We develop a general economic-ecological modelling framework for integrated analysis of biofuel policies. An economic model of farmers' decision making is combined with a biophysical model predicting the effects of farming practices on crop yields and relevant environmental impacts. They include GHG emissions over the life cycle, nitrogen and phosphorus runoff, and the quality of wildlife habitats. We apply our model to crop production in Finland. We find that under current biofuel production technology the case for promotion of biofuels is not as evident as has been generally thought. Only reed canary grass for biodiesel is unambiguously desirable, whereas biodiesel from rape seed and ethanol production from wheat and barley cause in most cases negative net impacts on the environment. Suggested policies in the US and the EU tend to improve slightly the environmental performance of biofuel production.     

An integrated decision-support approach in prioritizing risks of non-indigenous species in the face of high uncertainty

When evaluating the risks of future invasions, we often have sparse information on the likelihood that a species will arrive, establish and spread in a new environment, and on the potential impacts should this occur. Conventional risk assessment, therefore, is limited in providing guidance in managing the risk of non-indigenous species (NIS). However, risk management decisions must be made facing these uncertainties to avoid high and irreversible impacts.We develop an integrated ecological economic modeling and deliberative multi-criteria evaluation (DMCE) approach to support group decision-making in risk prioritization, using an example of ten NIS that could potentially impact Australian plant industries. This innovative approach seeks to combine the advantages of dynamic modeling with the benefits of DMCE in assessing and communicating uncertainty. The model unveils the complexity of the socio-ecological system of biological invasion, with a scenario analysis designed to interactively communicate scientific uncertainty to decision-makers. The DMCE provides a structured approach to identifying stakeholders' key concerns in addressing economic, social, and environmental dimensions of NIS risk explicitly. Functioning as a platform for risk communication, the DMCE also offers an opportunity for diverse views to enter the decision-making process and for the negotiation of consensus consensuses.     

我国生物质发电产业的现状及存在问题

生物质发电是一种环境友好的可再生能源利用模式,在我国拥有广阔的发展前景。随着《中华人民共和国可再生能源法》的颁布,近年来生物质发电产业发展迅速,总装机容量实现翻番,但企业经营状况并不好,由于成本、技术、政策等多方面原因出现了大面积亏损局面,致使其发展陷入瓶颈。首先对当前生物质发电相关的法律政策体系进行系统介绍,然后结合生物质产业现状分析其存在的问题,并提出相关政策建议。     

江西能源消费结构与经济发展的灰色关联分析——基于低碳经济的视角

能源是人类赖以生存和发展的重要物质基础,能源消费与经济发展有着十分密切的关系。江西作为能源资源匮乏的省份,发展低碳经济是弥补劣势的重要手段。利用灰色关联分析方法具体分析了江西省能源消费结构与经济发展的关系。结果表明,江西省应改善以煤炭为主的能源消费结构,大力发展低碳经济,逐步优化产业结构和能源消费结构。     

河北省农村基础设施建设的收入效应研究

运用1995～2008年的数据,采用ADF检验、协整检验等对河北省农民人均纯收入和农村用电量、农业基本建设投资额及农民家庭平均每户的交通运输、仓储和邮政业原值进行了实证分析。结果表明三者对农村经济增长具有不同程度的推动作用。政府应该通过明确农村基础设施供给中各级政府的职责,加大农村基础设施尤其是生产性基础设施的投资力度等措施来促进农村经济的发展。     

Foresight analysis of tilapia supply chains (Sistema Producto) in four states in Mexico: Scenarios and strategies for 2018

In order to increase competitiveness among individual producers and to encourage their integration, the federal government of Mexico has pursued the establishment, at both the state and national levels, of supply chains, or Sistema Producto (SP). For fisheries and aquaculture, 33 SPs exist at the state level and 7 at the national level, 1 of them for tilapia. The objective of this study is to carry out a foresight analysis (FA) of 4 tilapia SPs in Mexico—for the States of Colima, Sonora, Tabasco and Yucatán—analyzing their 2018 vision for the development of the tilapia chain. FA provides an integral vision of both the internal and external environments, identifying the key factors for each SP and helping to develop the best strategies in order to compete successfully. Sonora, Tabasco and Yucatán identify marketing aspects as key elements for their 10-year future: adding value to the product by means of new processing technologies, developing their own brand, and identifying and differentiating their product based on sanitary issues. Colima focuses its industry future success on efficiency improvements. Finally, the main technological disruptions identified by the 4 states are the incremental use of information technology, product and process certification, new hatcheries with genetically-improved fry, and new processing methodologies developed and/or applied.
