在9年樣本期內(nèi),包括上市公司,總共有大約55萬家企業(yè)出現(xiàn)。顯然,這是一個巨大的非平衡面板數(shù)據(jù)。由于企業(yè)關(guān)閉、改制、重組等各種原因,只有46 000萬多家企業(yè)約占樣本企業(yè)總數(shù)的8連續(xù)出現(xiàn)在整個樣本期內(nèi)。該數(shù)據(jù)庫樣本占據(jù)了中國工業(yè)企業(yè)的絕大部分比例。根據(jù)具有可比性的2004年*次全國經(jīng)濟普查年報,當(dāng)年工業(yè)企業(yè)銷售額為 442.81億元。而中國工業(yè)企業(yè)數(shù)據(jù)庫當(dāng)年全部樣本企業(yè)的銷售額為195 600億元,約占全國的89.5.
目前,除了經(jīng)濟普查數(shù)據(jù)庫之外,中國工業(yè)企業(yè)數(shù)據(jù)庫是可獲得的zui大的企業(yè)級數(shù)據(jù)庫。表1描述了1999~2007年企業(yè)總數(shù)和國有、集體、民營、外資企業(yè)含港、澳、臺企業(yè)的份額變化。可以看出,國有和集體企業(yè)的比例在顯著減少,從1999年的2 /3下降到2007年的不足1 /10,而民營企業(yè)的比例從不足20迅速增加到超過70.該表從一個側(cè)面反映了中國市場經(jīng)濟結(jié)構(gòu)的劇烈變動。
事實上,工業(yè)企業(yè)數(shù)據(jù)庫是zui全面的企業(yè)數(shù)據(jù)庫。該數(shù)據(jù)庫包括企業(yè)的兩類信息:一類是企業(yè)的基本情況,另一類是企業(yè)的財務(wù)數(shù)據(jù)。企業(yè)的基本情況包括:法人代碼、企業(yè)名稱、法人代表、、郵政編碼、具體地址、所屬行業(yè)、注冊類型所有制、隸屬關(guān)系、開業(yè)年份和職工人數(shù)等指標(biāo)。企業(yè)的財務(wù)數(shù)據(jù)則包括:流動資產(chǎn)、應(yīng)期第年濟經(jīng)界世中國工業(yè)企業(yè)數(shù)據(jù)庫的使用現(xiàn)狀和潛在問題學(xué)者們使用的該數(shù)據(jù)庫可能有幾個不同的來源,但是內(nèi)容相差很小。
