43、界上最多的科學(xué)家和工程師,但是其由于52%的工作人員無法讀寫,而同時(shí)成為世界上識(shí)字率最低的國(guó)家。正如表3所示,盡管有大量的工程師,但是印度每百萬人口里工程師的數(shù)量還是低于其他一些國(guó)家。由于緩慢增長(zhǎng)的干預(yù)型經(jīng)濟(jì)不能產(chǎn)生對(duì)工程師的足夠需求,相應(yīng)的就有對(duì)現(xiàn)存但未被雇用的工程師的過度依賴。</p><p> 大部分的印度軟件公司的職員都畢業(yè)于工程學(xué)院。根據(jù)Arora et al. (2000)的報(bào)告,大部分被訪企業(yè)只雇
44、用工程師。60家軟件公司的調(diào)查數(shù)據(jù)顯示,超過80%的公司雇員有工程師學(xué)位,只有13%是在軟件發(fā)展中被培訓(xùn)起來的非工程師。在采訪中,很多公司明確表示他們只雇用工程師。 </p><p> 在軟件行業(yè)發(fā)展的初期,由于需求遠(yuǎn)遠(yuǎn)小于每年的供給量,這種對(duì)工程師的偏好并不明顯或者不導(dǎo)致什么后果。印度總共有160,000各種各樣工程類畢業(yè)生。印度產(chǎn)業(yè)穩(wěn)定而快速的發(fā)展意味著在1998年和1999年間,被雇傭者的數(shù)量將會(huì)累計(jì)到近
45、250.000,預(yù)計(jì)將會(huì)在2000到2001年間突破400,000。即使軟件產(chǎn)業(yè)每年以50%的增長(zhǎng)率增長(zhǎng),甚至假設(shè)生產(chǎn)力提高,軟件產(chǎn)業(yè)似乎還是會(huì)將出現(xiàn)工程師供不應(yīng)求的局面。(參考 Arora, Asundi 和 Fernandes,《2000年細(xì)節(jié)》。) </p><p> 這些預(yù)言得到證據(jù)支持。軟件產(chǎn)業(yè)的工資率每年以20%的增長(zhǎng)率在增長(zhǎng),同時(shí)人員損耗率也是相當(dāng)?shù)母摺.?dāng)在1998年至1999年間,當(dāng)軟件產(chǎn)業(yè)被問
46、及列舉他們發(fā)展所面臨的三大問題時(shí),超過一半的公司(以超過100的公司為樣本),不考慮公司的時(shí)間、規(guī)模和市場(chǎng)導(dǎo)向(出口或者進(jìn)口),都不約而同的選擇了人員緊缺和人員損耗作為他們所面臨的最嚴(yán)重的問題。盡管愿意償付遠(yuǎn)遠(yuǎn)高于印度標(biāo)準(zhǔn)水平的工資, 很多企業(yè)最終還是發(fā)現(xiàn)難以吸引并且留住優(yōu)秀的軟件開發(fā)人才。</p><p> 公共政策對(duì)此做出的反應(yīng)是加強(qiáng)在工程學(xué)院上的投資,重視工程課程上的信息技術(shù),和信息技術(shù)機(jī)構(gòu)(IIIT)以
47、及更有名的印度技術(shù)機(jī)構(gòu)的創(chuàng)建等。盡管從表面上來看這些舉措是合理的,但是實(shí)際上這并不能解決問題。這些投資根本不可能在短期內(nèi)能顯著改善工程人員供給。同時(shí),如此大規(guī)模擴(kuò)容導(dǎo)致軟件產(chǎn)業(yè)發(fā)展趨向于抽調(diào)工程碩士和博士。一份最近對(duì)印度工程研究生教育的調(diào)查顯示,工程博士的數(shù)量已經(jīng)從1987年的675位下降到1995年的375位。同時(shí),擁有碩士頭銜的工程師的數(shù)量也只是緩慢增長(zhǎng),從1987-89年間的12,000位增長(zhǎng)到了1990-92年間的17,000位
48、。對(duì)印度技術(shù)機(jī)構(gòu)理工學(xué)校的調(diào)查顯示,大量的該校畢業(yè)生進(jìn)入信息技術(shù)部門工作,有時(shí)甚至高達(dá)90%。</p><p> 另外,表6顯示印度大部分工程學(xué)校集中在少部分的幾個(gè)州——Maharashtra, Karnataka, Tamil Nadu and Andhra Pradesh。同時(shí)其中大部分都是私立大學(xué),在這些學(xué)校的學(xué)生收到的補(bǔ)助遠(yuǎn)遠(yuǎn)小于就讀于州立大學(xué)的學(xué)生。但是,私立學(xué)院并未能在國(guó)家的其它部分?jǐn)U散開來是一個(gè)有
49、趣而費(fèi)解的現(xiàn)象。我們只能大概的估計(jì)這部分歸因于文化和政治因素,部分取決于在其它州人力資本投資的低收益率。并非巧合的,南部和西北在經(jīng)濟(jì)上確實(shí)是更發(fā)達(dá)。 </p><p> 我們認(rèn)為,盡管在工程教育方面的投資是必需的,但是解決問題的更有效的辦法應(yīng)該是依賴于對(duì)現(xiàn)有人力資源的合理利用。在這場(chǎng)爭(zhēng)論中的隱含假設(shè)是只有工程類畢業(yè)生才能勝任軟件開發(fā)任務(wù)。這個(gè)假設(shè)技術(shù)顯然是不合理的。首先,大部分現(xiàn)在軟件產(chǎn)業(yè)工作的工程師事實(shí)上都是
50、沒有接受過在軟件工程、電腦科學(xué)或者相關(guān)領(lǐng)域等的訓(xùn)練。其次,很大一部分工作是涉及到商業(yè)應(yīng)用,數(shù)據(jù)庫(kù)等。事實(shí)上,最初大量的工作涉及到從一個(gè)運(yùn)行平臺(tái)(通常如維護(hù))到另一個(gè)運(yùn)行平臺(tái)(如Unix平臺(tái))的運(yùn)用。這些工作只要求對(duì)軟件開發(fā)工具相當(dāng)熟悉,但并不要求對(duì)電腦結(jié)構(gòu)和運(yùn)行系統(tǒng)具有很深的認(rèn)識(shí)。最后,大部分的工作其實(shí)都是由一個(gè)個(gè)具有較低技術(shù)復(fù)雜性的小工程組成的。Arora et al(2000)在他們調(diào)查中發(fā)現(xiàn),公司最重要的出口工程的中等規(guī)模是150
51、個(gè)人,但平均有510人。這表明典型的出口工程甚至更小。更有甚者,大約一半的工作在印度國(guó)內(nèi)執(zhí)行,剩下的則在美國(guó)。</p><p> 當(dāng)迫于無奈,很多經(jīng)理也表示他們并不需要工程師:聰明的畢業(yè)生只要經(jīng)過適當(dāng)?shù)呐嘤?xùn),是能很快勝任何工作的。但是似乎對(duì)工程師的偏好是出于對(duì)顧客傳遞產(chǎn)品質(zhì)量信號(hào)的考慮。正如某一CEO所說,“雇傭任何一個(gè)優(yōu)秀學(xué)府的畢業(yè)生(印度排名前20的大學(xué)中的任何一所),給他們?nèi)齻€(gè)月的培訓(xùn),他們就能夠勝任項(xiàng)目
52、任務(wù)。事實(shí)上,我并不是完全需要這些工程師……但是我卻不想在我的顧客中以雇傭非技術(shù)工程大學(xué)的畢業(yè)生而出名?!保▉碜浴端孤?bào)告》,Arora et al 1999)。 </p><p> 這是一個(gè)“競(jìng)賽至上”的最好例子。受限于市場(chǎng)影響力,印度軟件出口商們總是試圖通過人才和生產(chǎn)過程質(zhì)量,甚至可能的話,人才經(jīng)驗(yàn)等方面來使自己在競(jìng)爭(zhēng)中脫穎而出。</p><p> 企業(yè)也有出于質(zhì)量方面的考慮。一些
53、被采訪的經(jīng)理表示受過工程類專門教育涉及到一系列問題解決技巧、邏輯思考的方法和學(xué)習(xí)工具,這些都有助于(雇員)快速適應(yīng)在技術(shù)、領(lǐng)域和任務(wù)方面的變化。由于印度公司提供的是跨領(lǐng)域和平臺(tái)的一系列服務(wù),因此這些能力是很重要的資本。另外一個(gè)重要的考慮是工程教育背景是勞動(dòng)力質(zhì)量的信號(hào)指示。印度工程類教育體系是非常嚴(yán)格的,因而成功獲得工程類學(xué)位的畢業(yè)生至少顯示了智力和勤奮能力。軟件公司可能因此更看重的是這些素質(zhì)而不是具體大量的工程類知識(shí)。 </p&
54、gt;<p> 如果事實(shí)如此,那么勞動(dòng)力市場(chǎng)的分配必定是缺乏效率的。事實(shí)上,軟件產(chǎn)業(yè)的發(fā)展部分是通過吸引來自別的產(chǎn)業(yè)的人才來實(shí)現(xiàn)的。在我們的采訪中,我們遇到大量的具有高度專業(yè)背景(如VLSI 設(shè)計(jì)和衛(wèi)星系統(tǒng))的人從事諸如數(shù)據(jù)庫(kù)設(shè)計(jì)和商業(yè)應(yīng)用軟件的開發(fā)。甚至有些高級(jí)工程師是來自政府研究和發(fā)展機(jī)構(gòu)。這樣一種資源轉(zhuǎn)換是同我們先前假設(shè)的軟件發(fā)展在印度所具有的相對(duì)優(yōu)勢(shì)所吻合的。當(dāng)然,印度經(jīng)濟(jì)存在很多扭曲的地方,這些都是在解讀市場(chǎng)信
55、號(hào)時(shí)所應(yīng)該警惕的。除了上述提到的改變經(jīng)濟(jì)活動(dòng)的組成,市場(chǎng)對(duì)工程師和經(jīng)理人日益增加的需求也將影響經(jīng)濟(jì)活動(dòng)的組織。正如我們?cè)诘诹糠忠愿喙P墨討論的那樣,對(duì)受訓(xùn)過的工程師和管理人員的需求增加也將影響資本和勞動(dòng)力(或者更確切的說物質(zhì)資本和人力資本)之間的平衡,從而引發(fā)組織革新。</p><p> 對(duì)人力資本更多的回報(bào)也引發(fā)了對(duì)其更多的投資。印度的中產(chǎn)階級(jí),總是依賴于教育,特別是諸如工程師和醫(yī)生的職業(yè)教育,作為改善經(jīng)濟(jì)
56、狀況的一種手段。然而印度經(jīng)濟(jì)的緩慢增長(zhǎng),使這類投資的回報(bào)率顯得并不很高。政府公共財(cái)政的謹(jǐn)慎狀態(tài)也限制了中央和州政府?dāng)U張第三方教育的能力。然而,快速增長(zhǎng)的軟件部門迅速分散。在軟件產(chǎn)業(yè)內(nèi)發(fā)展最迅速的部門之一既是私人培訓(xùn)。</p><p> 私人培訓(xùn)機(jī)構(gòu)對(duì)個(gè)體在軟件開發(fā)工作方面進(jìn)行專門培訓(xùn)。NASSCOM 估計(jì),在1998年,有3800家類似于的培訓(xùn)機(jī)構(gòu),而市場(chǎng)潛力卻是有30,000,000美元,盡管其中的70%相信
57、被NIIT和Aptech所占領(lǐng)。私人培訓(xùn)機(jī)構(gòu)在幫助在職軟件開發(fā)員獲得新的技術(shù)上也是非常重要的。很多工程師也參加私人培訓(xùn)機(jī)構(gòu)進(jìn)修。私人培訓(xùn)機(jī)構(gòu)在印度城市的出現(xiàn),使軟件開發(fā)人員獲得這些機(jī)構(gòu)的認(rèn)證和證書的變得更加可能。</p><p> 同時(shí)值得一提的是,這是私人部門對(duì)市場(chǎng)機(jī)會(huì)——對(duì)特殊技能訓(xùn)練需求的反應(yīng)。在美國(guó)和其它的國(guó)家,公司為了利益會(huì)和各種各樣的公共機(jī)構(gòu)(如公立大學(xué))進(jìn)行競(jìng)爭(zhēng)。在印度,私人培訓(xùn)機(jī)構(gòu)的快速成長(zhǎng),表
58、明經(jīng)濟(jì)環(huán)境的變化和企業(yè)家行為從純粹的尋租向經(jīng)濟(jì)效率性領(lǐng)域轉(zhuǎn)軌。這種轉(zhuǎn)變至少間接上是歸因于軟件產(chǎn)業(yè)的快速發(fā)展。</p><p> 綜上所述,我們認(rèn)為,直到現(xiàn)在,證據(jù)顯示受過訓(xùn)練的工程類人才的過度供給是印度公司一個(gè)巨大的競(jìng)爭(zhēng)優(yōu)勢(shì)。同樣的,這種過度供給也將導(dǎo)致公司缺乏人盡其用的激勵(lì)。甚至,產(chǎn)業(yè)發(fā)展和高工資不斷不僅吸引著新畢業(yè)的工程師,還吸引了包括工程師、經(jīng)理和來自其它產(chǎn)業(yè)部門的專家。 </p><
