煤矿工作总结 文档美国小型和大型商业银行的利润效率来源及差异

审时度势更新观念抓管理低调务实精诚团结求发展先进表彰大会上的讲话与会的各位领导及同志们上午好！今天在这里举行“XX煤矿20**年度先进表彰大会”，我代表XXX煤业有限责任公司的全体员工，首先向董事长、关心和支持梁洼工作的各位副总、部室领导、兄弟单位及职工家属表示亲切的慰问和衷心的问候，向各位劳模、先进工作者表示崇高的敬意。在此我向诸位拜个早年，祝大家“新年愉快，身体健康，万事如意”。一、工作回顾（一）安全方面1、狠抓培训提高素质2013年度公司注重安全培训，把培训按系统、工种、重点、时期分类培训，并严格按文件考核，把培训绩效纳入工资考核，规范了培训管理，从而使公司员工熟悉工作标准，懂得规程，知道操作程序，提高岗位安全风险的预知与预控，转变了思想观念，树立了“安全第一”的理念，给公司的安全生产奠定了基础。2、安全管理方面2013年注重从隐患排查与治理、系统主体责任的明确与落实和安全考核与责任追究等三方面的工作。（1）隐患排查与治理公司严格落实系统自查自纠主体责任；部室技术监督指导责任；安全全面监督落实责任；经理带班现场排查跟踪落实责任。层层把关，横到边纵到底随时入井督查作业现场安全隐患与操作行为，并跟踪落实整改结果，全年共查出隐患条，整改条。（2）系统主体责任的明确与落实2013年严格落实【2013】2号《XXX煤业有限责任公司安全隐患治理责任追究及奖惩办法》明确了系统安全工作职责，安全工作标准和责任追究，对隐患分级按期整改，对整改不及时、整改不合格或重复的对系统经理、主管科室及主管区队进行责任追究；（3）严格安全考核与责任追究把系统安全质量标准化考核、优秀区队考核、先进班组考核、管理人员工资考核、最佳基层管理人员、安全标兵及年度先进工作者考核列入安全考核内容，并按文件要求进行事故责任追究制（2103年已对修护队、运输队个别队长进行免职追究）、加大安全管理力度，激发公司上下参与安全管理的积极性，取得了良好的效果。3、工程质量管理2013年度公司下发了下发XXX【2012】58号文件《关于工程质量监督管理办法的通知》规范了工程验收标准和验收制度，对不合格的工程杜绝验收结算，遏制了不合格工程，使巷道施工标准有了提高。4、安全指标2013年总体消灭了重伤以上事故；但发生几起零打碎敲轻伤事故，二级以上工程、机电事故有所下降，作业现场的隐患也得到有效遏制，职工的操作行为得到进一步规范。（二）指标完成情况采区接替紧张；由于煤炭市场影响煤质挑剔，为顺应市场需求，2013年度因地质多变对XXX工作面及21091采面4次改造，累计改造掘进进尺510.2m,给公司的原煤生产造成影响，但对煤质管理打下基础；2、生产指标（1）2013年度计划生产原煤XXXX吨，实际完成XXX吨；计划销售XXXX吨，实际完成销售XXXXXXT（2）开拓进尺计划1560m,实际完成XXXXm，8月份以来通过总公司对25采区皮带大巷供车问题协调，开拓进尺连续完成并超额计划。（3）掘进进尺全年完成XXXXXm,由于领导重视方法得当，21091采面顺利提前15天完成贯通。（4）修护进尺XXXXm，由于修护巷道安排合理较去年同比减少XXXXm.3、其它指标（1）完成XX采区两条主运输大巷的开拓主体工程和变电所主体工程。（2）保持国家二级标准化矿井（三）其它方面1、增加节支为认真落实总公司【2013】36号文件精神，XX公司下发XXX【2013】44号文及XXX【2013】49号《XX公司生产任务工效责任追究若干规定》公司实行安全、工效、材料回收及重复利用做到日清月结，发现问题立即分析原因、立即追究、立即采取措施8至12月份单工回采、开拓、掘进及修护效率明显提高，修旧利废和回收材料累计XXX元。2、人员组织方面公司根据实际情况制定切实可行的措施，有效的增强区队生产人员，今年10份公司出台管理人员组织人员措施，对公司的一线人员组织起到足进作用。3、特殊措施落实方面特殊时段安全及生产特殊措施，及时足进安全指标控制及生产计划完成。根据季节制定了夏秋保勤措施、8月份对XX采区皮带大巷开拓供车制定特殊保障措施、12月份根据XXXXX采面治水情况制定了XXXX1采面临时贯眼管通奖励措施。二、存在的问题1、安全管理方面还存在薄弱环节，零打碎敲事故还时有发生；2、内部管理有漏洞，材料费用超支比较严重，生产成本居高不下；3、煤质管理时有放松现象。三、20**年工作打算1、狠抓培训，提高全员素质和管理人员思想观念。2、狠抓安全风险预知预控管理，不断提高全员安全风险3、在安全管理的基础上，注重做好隐患排查与治理、系统主体责任的明确与落实和安全考核与责任追究等三方面的工作，严格按照一级安全质量标准化标准落实工作，打造安全环境，为实现“安全生产5000天”打下坚实基础。4、狠抓开拓进度，缓解采区接替。5、加大掘进步伐满足生产需要，保证采面正常接替工作。6、狠抓经营管理，消除浪费实现企业效益最大化，保持矿区和谐稳定发展。总之，2013年度，在总公司领导的正确指引和帮助下，通过加强现场安全管理，加强培训，推行安全管理精细化，加强安全班组建设，公司各项管理走上了良性轨道，取得了一点成绩，但与领导的要求还有一定差距。各级管理人员的业务水平还有待进一步提高；企业精细化管理还有待我们实现。瞻望未来，道路还很长，肩上的担子还很重，我们一定要紧密团结在以李总的周围，牢固树立“安全第一，预防为主，以人为本”的思想，以质量求安全、以安全求生存、以矿井标准化求发展。脚踏实地，大胆管理，勇于创新，认真工作，实现一级标准化矿井、努力完成20**年的各项指标，实现安全、稳定、和谐、发展的局面。谢谢各位！最后预祝大家，马年身体健康，工作顺利，合家欢乐，马上发财。20**年1月27日本科毕业论文外文翻译外文题目：ProfitefficiencysourcesanddifferencesamongsmallandLargeU.Scommercialbanks出处：Journalofeconomicandfinance(2005):289-299作者：AigbeAkhigbeandJamesMcNulty原文：IntroductionScaleeconomiesinbankinghavelongbeenofinteresttofinancialeconomists,andthisinteresthasbeenheightenedinrecentyearsbytwodevelopments.Thefirstisincreasedconcernaboutthesurvivabilityofsmallcommunitybanksinaneraofbankconsolidation.ThisthemewasthesubjectofaMarch2003conferenceattheFederalReserveBankofChicagoandformedthebasisforaspecialMarch2004issueoftheJournalofFinancialServicesResearch.Theseconddevelopmentisrecentacademicresearchsuggestingthatsmallbanksmayhavebothaninformationadvantageoverlargebanks,asinNakamura(1993),Mester,Nakamura,andRenault(2001),andCarterandMcNulty(2004),andanincentivetousethisinformationadvantageinthelendingprocess.Bergeretal.(2002)provideevidenceonthesecondpoint.Theysuggestthatsmallbanksmayhaveacomparativeadvantageindevelopingandusingthe“soft”informationoftenassociatedwithsmallbusinesslending.PROFEFFisaneconometricfinancialperformancemeasurethatindicateshowactualfinancialperformancecomparestoatheoreticalbest-practicefrontier.Consideringdifferencesin,andsourcesof,profitefficiency(PROFEFF)bybanksizegroupscanhelpshedlightontheissueofwhichbanksusetheircapitalmoreefficiently(providedprofitsarenormalizedbyequity,whichistheapproachwetakeinthispaper).RelevantLiteratureandEstimationIssuesMoststudiesdoneinthe1980sandearly1990ssuggestthatscaleeconomiesareslightornonexistentbeyondassetsizesof$50to$100million.SomeearlyexamplesareBenston,Hanweck,andHumphrey(1982),Gilligan,Smirlock,andMarshall(1984),Clark(1984),Nelson(1985),andBerger,Hanweck,andHumphrey(1987).Using1984data,BergerandHumphrey(1991)findthateconomiesofscaleatthefirmlevelareexhaustedbeyond$200millioninassetsize.Sincethisinfluentialstudy,whichfoundthatgainsfromreducingcostinefficienciesdominategainsfromrealizingscaleeconomies,thefocusofmoststudieshasshiftedtoinefficienciesandhenceawayfromoptimumsize.However,usingcostefficiency,BergerandMester(1997)concludethatscaleeconomiesareexhaustedwellbefore$10billioninassetsize.Sincethesestudiesestimatecosteconomies,theycannotdirectlyaddressthepossibilitythatrevenuesmaybemorethanproportionatelyhigherforlargerbanks.However,anotherrelatedtrendinthisliteraturehasbeenincreasedrecognitionthatprofitefficiencyisamoreappropriatetechniquetouseinevaluatingbankperformancethancostefficiencysincePROFEFFincorporatesbothrevenuesandcosts.RecentprofitefficiencystudiesincludeAltunbas,Evans,andMolyneux(2001),AkhigbeandMcNulty(2003),BergerandMester(1997,2001),DeYoungandHasan(1998),andDeYoungandNolle(1996),amongothers.

程序允许利润效率措施有最大的灵活性——小银行的利润效率不受大银行的活动和资产负债表结构的任何约束或影响，反之亦然。因此，当我们看到这三个群体的利润效率的决定因素，如果它们是不同的，这将反应真正的差别，如果它们是相同的，所有的银行将不会因为相同的前沿被制裁。我们认识到的另一类说法是，在比较不同银行的业绩时，人们通常想要使用相同的测试，而不是两个或者三个不同的测试。（先前的文章中我们自己讨论过这个论点）各种规模的团体银行的利润效率趋势近几年来，小型银行的利润效率急剧下降，从1995年的0.778下降到2001年的0.702。我们认为这种下降的假设可能反映了在小银行类别中的从头银行数量的增加。联邦存款保险公司的数据表明，在1992年和1994年之间，每年只有74家特许的新银行，这无疑反映了当时银行业的低迷状态。与此相反，在从1995年至2000年的六年时间里，平均每年有175家特许成立的银行。许多银行在特许成立之后的很多年规模仍然很小。DeYoung和Hasan（1998）表明，从头银行的利润效率比老的，相同规模的银行的利润效率少得多。表1中在一亿美元以下的银行类别的百分比中从头银行（未满10年）已经从百分之11.4上升到百分之13.5。此外，DeYoung和Hasan（1998）指出，新银行前三年的经营显示出的利润效率特别低。近几年，数据更加分散的小银行也支持这个解释。因此，在1995年至2001年的小型银行至少部分利润效率下降的假设反映了从头银行在样本中出现的合理性。与小型银行相反，当把中位数和均值的趋势都考虑在内时，中型银行和大型银行的利润效率相对稳定。举例来说，意味着在整个期间内中型银行的利润效率高于0.81而大型银行的利润效率仍高于0.84。然而，在估计中有所下降是显而易见的，这可能在某种程度上反映了一个事实，银行在所有规模团体中较少使用杠杆是因为来自监管机构的压力增加了他们的资产负债的资本金额。利润效率的回归的相关性分析结果如前所诉，我们考虑相关的意义之间差异的大小作为一组相关指示，不同规模的银行有不同的方式来实现高盈利的能力。在中型和大型银行中股本/资产的比率（股权）为负的（如预期），而且是显著的。这表明了，在其他条件不变时，更多利润，高效率的银行在这些相同的大小团体中比其他的银行使用了更多的杠杆（较少的权益）。对于小型银行来说年龄是积极的，重要的，但是对大型银行而言不是。这是个一致的概念，一个强有力的信用文化的建立是中小银行盈利的重要因素。信贷员的世代重叠（在当地社区，每一代的培训下发放贷款）和关系的发展，是建立这样一种文化的重要元素。这些战略的成功实施将要求银行存在相当长的时间。这就是美斯特（1997）讨论的“从做里面学习”，如上所诉。中小银行的不良市场贷款率（MKTNPL）是显著的，与预期的一样是负的，但是实际上对于大银行来说是正的。这个比例对较大的银行来说不是特别重要，因为它仅考虑家庭办公所在地县级那里的银行的不良贷款。多数的大银行有一个以上的县办事处和贷款。对于中小银行来说，会员在一家销售控股公司（MBHC）是具有消极的意义和作用的，但对于大银行来说不是。显然，最成功的中小银行是独立的。它还表明了，大型银行控股公司的成员不太可能受到控股公司发展水平的影响，而中小银行控股公司的成员可能受到的影响较大。相对的不良贷款比例（RELNPL）是显著的复数，但仅仅是对中型银行而言。在中小银行中，费用收入的差异是盈利能力差异的一个重要来源（注意显著性水平非常高），但是对于大型银行来说不是。对此最可能的解释是，几乎所有大型银行都依赖费用收入，而不是说费用收入对这些银行不重要。(见附表1)年的虚拟变量也只对中小银行具有重要的意义。这表明，随着时间的推移大型银行比其他的银行具有更多持续的盈利能力。竞争条件很重要，但仅仅是对两个较小的组织而言。小银行之间的利润效率的差异与赫芬达尔指数是正相关的。换句话说，在其他条件不变时，市场越集中，利润效率就越高，而这也正是我们所期望的。与此有同样关系的是中型银行，大型银行则不适合。BergerandMester(1997)andAkhigbeandMcNulty(2003)也发现了利润效率与赫芬达尔指数之间的正相关的关系。此外，对其他大部分的相关系数的研究与AkhigbeandMcNulty(2003)的研究结果是一致的。事实上，不同规模的银行要通过不同的方式实现高（或者低）的利润效率是符合上述DeYoung,Hunter和Udell(2004)的分析的，不同规模的银行要有不同的商业模式。总结和结论我们研究了1995年至2001年期间的小型银行（资产低于一亿美元），中型银行（一亿美元至十亿美元）和大型银行（十亿美元以上）之间利润效率的差异，以及这些差异的来源。由于我们采用权益计算正常化的利润效率，所以大银行的排名最高也就不足为奇。但是，这些差异都相当的大。对于整个的期间，小型银行的平均利润效率是0.752，大型银行的平均利润效率是0.823，而大型银行的平均利润效率0.856。换句话说，小型银行与大型银行的利润效率差距超过了10个基点，这在经济上（和统计上）是相当显著的。小型银行可以通过成长，通过低违约率的市场运作，通过成为独立的控股公司，通过产生高的费用收入，通过在一个集中的市场中经营和通过贷款来获取更多自己的资产而不是有价证券来达到高的利润效率。大型银行主要是通过使用更多的杠杆来实现高的利润效率，这是因为其他变量都是没有意义的。DeYoung,Hunter和Udell(2004)指出了不同类型的银行有着不同的商业模式。小型银行的商业模式是客定制的和个性化的服务，但是成本高；而大型银行的目标则是对庞大的客户群体在较低的成本下提供相对统一的金融服务。我们的分析与不同类型的银行以不同的方式实现高盈利能力的这个概念是一致的。hinese
