Comparative Research Between Price Matching Guarantee and Price Beating Guarantee

在现实生活中，价差补偿策略是经常被商家使用的，如屈臣氏、沃尔玛、家乐福等零售巨头都常常会有“低价保证”“价差退返”等承诺来吸引消费者。而价差补偿策略的两种主要形式，价格匹配策略（Pricematching）和价格对抗策略（Pricebeating），它们各自的作用和影响一直在学术圈都有争论——是提高竞争还是促进合谋。本文主要是从商家和消费者两个角度，来对价格匹配和价格对抗策略作一个较为全面的解读、分析和讨论。从商家的角度考量，通过对Bertrand完全替代和部分替代模型在对称市场（相同成本）和非对称市场（不同成本）这样四种情形的分类研究，我们发现尽管价格匹配策略的使用可能也会出现竞争性的结果，...The price guarantee is widely used in the real life. retail giants like Watson, Wal Mart, Carrefour often make ”low price guarantee”, ”price difference return” commitment to attract consumers. The two main forms of price guarantee are price matchin guarantee and price beating guarantee. Their roles and impact on the market has been in the academic dispute: improving competition or faciliating coll...学位：经济学硕士院系专业：王亚南经济研究院_西方经济学学号：2772013115277

The Research on The Problem Of The Efficiency Of Investment In Chinese Transformation Period

中国经济发展中一个重要的问题是投资的效率问题，增长速度之争的背后很重要的是投资效率高低之争。我国目前的状况是投资对GDP的贡献大，但投资的效率却不容乐观。增长的可持续性在很大程度上不仅取决于要素的供给能力，而更重要的是取决于有效配置要素的能力。在这个意义上，投资的选择及资本运作的效率至关重要。因此，我们逐步将目光集中在投资效率的测度与研判上，用理论与实际相结合的视角透视我国高投资、高增长、低效率的深层原因，试图找出适合我国经济转型期特点的经济改革方案。本文的研究以新经济增长理论为基础，从我国整体投资情况出发，主要从实证角度来分析影响中国东、中、西部地区经济增长的因素。并将主要研究国有投资、民营...The efficiency of investment is an important problem in Chinese economic development. The efficiency is definitely more important than the speed of the economic growth. Although the investment contributes a lot to the GDP, the efficiency of investment is not that good.

Study on The Protection of the Creditor of One-Man Company

2006年1月1日，备受人们关注的《中华人民共和国公司法》（以下简称《公司法》）开始正式实施，一人公司的形式得到了法律的认可，充分体现了国家更加重视建设效率、公平的市场经济环境的决心。但一人公司本身的特性所带来的法律风险和道德风险使债权人利益被侵害指数大大增加，在这种背景之下如何构建一套合理的债权人保护机制，对于完善我国《公司法》的理论和实践，促进社会主义现代化建设，具有重大的现实意义。通过比较分析，本文得出的观点有：股东本位思想和利益相关者理论不矛盾；一人公司在多视角下存在的多重必然性；一人公司债权人保护的特殊性；一人公司债权人保护特点及发展趋势；我国一人公司债权人保护制度的评析及完善建议。...On Jan 1, 2006, the attention-attracting Corporation Law of the People’s Republic of China was officially implemented.

清洁能源发展、二氧化碳减排与区域经济增长

中国现在是世界上最大的石油进口国和二氧化碳排放国,积极发展清洁能源对于保障能源安全、控制二氧化碳排放和实现绿色经济增长具有重要现实意义。而清洁能源发展对二氧化碳减排的作用到底有多大?需要大量资金投入的清洁能源发展能否促进经济增长?这是各级政府管理部门和相关学者关注的焦点。为了回答这两个关键问题,本文基于中国30个省区市1979—2016年的真实数据和2017—2030年的预测数据构成的面板数据,运用非参数可加回归模型深入探究清洁能源发展对区域经济增长和二氧化碳排放的线性和非线性影响。研究结果显示:单纯从线性角度来看,清洁能源发展没有起到显著减少二氧化碳排放和促进经济增长的作用。但是,这并不代表清洁能源在不同发展阶段对二氧化碳减排和经济增长的积极影响也是有限的。非线性结果表明:在不同发展阶段,清洁能源发展对东中西三大区域二氧化碳排放和经济增长的影响差异明显。因此,中央和各地方政府应该根据清洁能源在不同发展阶段发挥的不同作用、因时施策,以充分发挥清洁能源发展在二氧化碳减排和经济增长中的促进作用

The Design of Self-Adaptive Control System for Grinding Force

可转位刀片的传统磨削加工大多采用恒进给量控制法,若工件的余量不均、材质不均、磨削速度较高、砂轮的切削性能较差时,在进给速度较大时,将对工件的加工表面质量产生不良影响,如表面粗糙度增大,工件表面烧伤和产生微裂纹,砂轮磨损加剧,砂轮轴变形,甚至砂轮崩裂。若降低进给速度势必会影响加工效率。自适应加工技术是解决上述问题的重要途径,论文讨论了应用该技术对影响加工效率和精度的切削力、转矩、功率、刀具磨损、尺寸精度、和表面粗糙度等物理量进行检测、建模、提取特征,对进给速度、主轴转速等工艺参数进行实时控制,使机床的工艺系统在高效加工中处于最佳状态。Mostly,the traditional method of grinding indexable insert is to keep constant feed rate.If the allowance of workpiece was uneven,the material was nonuniform,the speed of grinding was high and cutting performance of grinding wheel was poor,a large feed rate would exert a bad effect on the quality of manufacturing.For example,surface roughness would increase,surface would burn and emerge tiny fissures,grind wheel wear would exacerbate,shaft would distort,even crack.However,if you reduce the feed rate,efficiency will certainly be low.Self-adaptive manufacturing technology is an important way to solve those problems above.The technology detects,builds up models and extracts characteristics of physical quantities,such as force,torque,power,tool wear,dimensional accuracy and surface roughness which affect processing efficiency and precision.Then,it keeps feed rate,spindle speed and other parameters in real-time control to ensure the best condition.国家“高档数控机床与基础制造装备”科技重大专项资助(2010ZX04001-162

Study on γ-Aminopropyltrimethoxysilane Films on Transition Metal Surfaces

本文对在过渡金属铁、镍电极表面制备得到的γ-氨丙基三甲氧基硅烷(γ-APS)膜进行了研究。实验中对硅烷膜用X-射线光电子能谱(XPS)、现场表面增强拉曼散射光谱(SERS)和原子力显微镜(AFM)进行了表征。X-射线光电子能谱(XPS)的结果发现存在两个N1s峰,表明γ-APS膜中的氨基有两种存在方式:自由氨基和质子化氨基。实验中还发现现场表面增强拉曼散射光谱(SERS)是研究金属/γ-APS体系中界面层结构非常有效的手段,SERS结果表明硅醇羟基和氨基发生了竞争吸附,且γ-APS分子在外加电位等条件的影响下吸附状态会发生一定变化。原子力显微镜(AFM)的表征结果在微观上显示电极表面的γ-APS膜上形成了一种较规则的微孔结构,这种结构可能与基底的性质有关。The films of γaminopropyltrimethoxysilane (γAPS) prepared on transition metal(iron and nickel electrode) surfaces were studied. The silane films were characterized by Xray photoelectron spectroscopy (XPS), insitu Surfaceenhanced Raman spectroscopy (SERS), atom force microscopy (AFM). XPS results of γAPS modified electrodes showed the presence of two nitrogen binding energy peaks indicating the presence of the amine in two different states, the free amine and the protonated state. It has been found that the insitu surfaceenhanced Raman spectroscopy are useful for diagnosing the structure of the γAPS/metal interface. Results of SERS indicated that the silanol and amino groups adsorbed competitively on the metal surfaces. At the same time, the electrode potential has great influence on the nature of adsorption of these head groups. The films of γAPS on electrode surfaces was characterized by atom force microscopy and showed a kind of regular porous structure on the microscopic scale, it may due to the roughness of the electrode surfaces
