簡介：中文4166字畢業(yè)設(shè)計論文外文翻譯譯文譯文中國中小企業(yè)信用危機(jī)研究中國中小企業(yè)信用危機(jī)研究大衛(wèi)羅奇知名的中國經(jīng)濟(jì)及政治分析師摘自雜志“REVIEWOFINTERNATIONALECONOMICS”第19期161173一、中小企業(yè)在中國經(jīng)濟(jì)發(fā)展中的重要地位和作用中小企業(yè)在中國社會經(jīng)濟(jì)發(fā)展中始終具有十分重要的地位和作用。加快中小企業(yè)的發(fā)展，不僅有利于促進(jìn)中國國民經(jīng)濟(jì)持續(xù)快速健康發(fā)展，緩解社會就業(yè)壓力，保持社會穩(wěn)定，而且有利于推進(jìn)技術(shù)進(jìn)步，優(yōu)化經(jīng)濟(jì)結(jié)構(gòu)，滿足社會多樣化的需求，形成合理有序的社會化生產(chǎn)分工體系，保持經(jīng)濟(jì)活力。（一）中小企業(yè)是推動中國國民經(jīng)濟(jì)持續(xù)快速健康發(fā)展的重要力量中小企業(yè)機(jī)制靈活，富于創(chuàng)新，參與那些大企業(yè)不愿涉足的“多品種”“小批量”和維修服務(wù)等領(lǐng)域，貼近市場，與人民群眾生活息息相關(guān)，是活躍市場的重要力量，也為國家提供了大量的稅源。（二）中小企業(yè)對創(chuàng)造就業(yè)機(jī)會、緩解社會就業(yè)壓力起著獨特的作用中小企業(yè)多數(shù)為勞動密集型企業(yè)，能創(chuàng)造大量的就業(yè)機(jī)會，緩解社會就業(yè)壓力，保持社會穩(wěn)定。據(jù)統(tǒng)計中國的中小企業(yè)提供了全社會約75的就業(yè)機(jī)會。（三）中小企業(yè)為社會化大生產(chǎn)提供了必需的協(xié)作服務(wù)中國社會化大生產(chǎn)的基本特點是專業(yè)化協(xié)作，社會分工精細(xì)。大企業(yè)的發(fā)展必然要求中小企業(yè)為其提供服務(wù)。“小而優(yōu)”“小而?！钡闹行∑髽I(yè)，可以靈活組織生產(chǎn)，為大企業(yè)提供協(xié)作服務(wù)，形成大中小企業(yè)相互依存的經(jīng)濟(jì)格局，保持社會總供給與總需求的平衡。（四）中小企業(yè)對技術(shù)創(chuàng)新有著重要作用中小企業(yè)經(jīng)營靈活，使得某些行業(yè)的技術(shù)創(chuàng)新首先適宜中小企業(yè)研發(fā)及應(yīng)用，大大縮短了科學(xué)技術(shù)轉(zhuǎn)化為生產(chǎn)力的進(jìn)程。（五）中小企業(yè)的發(fā)展帶動了中小城鎮(zhèn)建設(shè)更沒有專門為中小企業(yè)服務(wù)的融資體系。因此，中小企業(yè)相對于大型企業(yè)來說，融資渠道不暢通、技術(shù)裝備相對落后、人員素質(zhì)整體不高、科技含量低和產(chǎn)品質(zhì)量不高，市場競爭力弱以及法律、政策扶持與保護(hù)力度不夠等，這些都成為制約中小企業(yè)生存和發(fā)展的主要因素。同時，中國中小企業(yè)規(guī)模相對較小、風(fēng)險大、信用能力較低，一般資金所有者或金融機(jī)構(gòu)在資金融通上都普遍采用謹(jǐn)慎性原則，增加了其融資的難度。（二）產(chǎn)權(quán)制度不健全產(chǎn)權(quán)是信譽的基礎(chǔ)，因此中國中小企業(yè)追求長期利益的積極性可以歸結(jié)為產(chǎn)權(quán)問題。中國中小企業(yè)不講信譽的根本原因一方面是他們感到他們的產(chǎn)權(quán)沒有得到可靠的保障，缺乏安全感，沒有穩(wěn)定的預(yù)期，自然就只能追求短平快，而不可能投資建立起完善、健全的信譽制度；另一方面是在“家族式”的中小企業(yè)中，尤其是那些具有血緣、親緣、地緣及家企不分的企業(yè)，由于企業(yè)產(chǎn)權(quán)界限不清，由此界定的有關(guān)人員相互間的權(quán)、責(zé)、利不明確，從根本上影響了企業(yè)的治理結(jié)構(gòu)，進(jìn)一步影響了企業(yè)的權(quán)威和信譽。（三）經(jīng)營管理水平不高，管理人員綜合素質(zhì)差中國中小企業(yè)缺乏系統(tǒng)、及時、全面的市場銷售信息，因決策失誤導(dǎo)致其陷入困境的現(xiàn)象比較普遍。一些企業(yè)雖然研制和開發(fā)出了好的產(chǎn)品，卻因為管理層經(jīng)營管理水平較差，再加上缺乏市場觀念和用戶意識，輕視產(chǎn)品質(zhì)量以及忽視了對客戶服務(wù)質(zhì)量的改善和提高，輕易地在激烈的市場競爭中丟掉了其經(jīng)過前人長期艱苦努力所營建起來的品牌、信譽等優(yōu)勢。同時，中小企業(yè)職工素質(zhì)偏低，企業(yè)內(nèi)部缺少精通經(jīng)營、技術(shù)、管理方面的人才，再加上企業(yè)外部環(huán)境競爭日趨激烈、企業(yè)效益不佳，中小企業(yè)更難以吸引并留住人才，結(jié)果更進(jìn)一步延緩了中小企業(yè)職工隊伍素質(zhì)提升的速度，使中小企業(yè)陷入低效益低素質(zhì)低效益的惡性循環(huán)之中。（四）會計監(jiān)管弱化中國目前中小企業(yè)會計監(jiān)管處于監(jiān)管弱化狀態(tài)。具體表現(xiàn)在，政府監(jiān)管分散、社會監(jiān)管乏力、內(nèi)部監(jiān)管薄弱。目前，由于上述三種監(jiān)管的主管部門不同，各部門之間相互協(xié)調(diào)力度較差，或者干脆是各自為戰(zhàn)，因而在實際監(jiān)管過程中，往往會出現(xiàn)一個地區(qū)、一個企業(yè)或者同一個事項剛剛由上一個監(jiān)管部門檢查完畢，緊接著另一個監(jiān)管部門又重新檢查，這樣勢必形成針對同一個企業(yè)、同一個事項、同一套資料，有數(shù)個部門進(jìn)行重復(fù)監(jiān)督，不但造成了經(jīng)
