现行成品油定价机制背后的税利博弈简

自成品油定价机制改革以来,成品油定价机制饱受争议,油价一直是人们关注的焦点。分析了国内需求拉动和国际输入型价格变动是引起油价上涨的主要原因;油价变动对用油企业、个人及产油企业的影响。随着我国国内成品油需求量日益增加,引发用油企业、个人及产油的上游企业与下游企业以及国家各方不断进行利益博弈,提出只有通过国家税收政策经济杠杆的调节作用,才能逐步调整各方利益及分配关系。     

我国成品油流通行业市场进入的博弈分析

The matched pair sign test using bivariate ranked set sampling for different ranking based schemes

Bivariate rank set sample (BVRSS) matched pair sign test is introduced and investigated for different ranking based schemes. We show that this test is asymptotically more efficient and more powerful than its counterpart sign test based on a bivariate simple random sample (BVSRS) for different ranking schemes. The asymptotic null distribution and the efficiency of the test are derived. Pitman’s asymptotic relative efficiency is used to compare the asymptotic performance of the matched pair sign test using BVRSS versus using BVSRS in all ranking cases. For small sample sizes, the bootstrap method is used to estimate P-values. Numerical comparisons are used to gain insight about the efficiency of the BVRSS sign test compared to the BVSRS sign test. Our numerical and theoretical results indicate that using any ranking scheme of BVRSS for the matched pair sign test is more efficient than using BVSRS.     

自由与迷失——审美游戏论批判

所谓审美游戏论就是以游戏来描述审美存在,以游戏特性来确立审美的独立性、合法性与本体性的理论话语.从审美游戏论的话语历史出发,关注其理论建构的可能性与界限,才能把握审美游戏论所阐释的审美特性.     

A New Multicriteria Risk Mapping Approach Based on a Multiattribute Frontier Concept

Invasive species risk maps provide broad guidance on where to allocate resources for pest monitoring and regulation, but they often present individual risk components (such as climatic suitability, host abundance, or introduction potential) as independent entities. These independent risk components are integrated using various multicriteria analysis techniques that typically require prior knowledge of the risk components’ importance. Such information is often nonexistent for many invasive pests. This study proposes a new approach for building integrated risk maps using the principle of a multiattribute efficient frontier and analyzing the partial order of elements of a risk map as distributed in multidimensional criteria space. The integrated risks are estimated as subsequent multiattribute frontiers in dimensions of individual risk criteria. We demonstrate the approach with the example of Agrilus biguttatus Fabricius, a high‐risk pest that may threaten North American oak forests in the near future. Drawing on U.S. and Canadian data, we compare the performance of the multiattribute ranking against a multicriteria linear weighted averaging technique in the presence of uncertainties, using the concept of robustness from info‐gap decision theory. The results show major geographic hotspots where the consideration of tradeoffs between multiple risk components changes integrated risk rankings. Both methods delineate similar geographical regions of high and low risks. Overall, aggregation based on a delineation of multiattribute efficient frontiers can be a useful tool to prioritize risks for anticipated invasive pests, which usually have an extremely poor prior knowledge base.

高校经济性腐败临界行为及机理研究

教育腐败危及公平和社会公信力，目前，高校腐败已经成为整个社会关注的热点。文章以博弈经济学的视角，分析了高校监督者和高校从业者之间的博弈关系，揭示了高校经济性腐败的临界行为，研究表明，高校从业者临界收益与监督概率、从业者收入、贴现因子及从业者任期正相关，与从业者风险好恶系数负相关，高校监督者临界监督成本与背德未被发现时收益、从业者收入、背德概率、贴现因子及从业者任期正相关，与监督者风险好恶系数负相关，在此基础上，提出应采取选择品德高尚的高校从业者、提高腐败成本、建立有效的监督和激励机制等预防高校腐败的措施。
