為此本文以嚴守價值鏈的基本概念的態度，遵循企業經營管理展開始於戰略的基本路徑，沿著價值鏈的構造必須建築于深入的戰略分析研究的基礎之上的思路，展開了對價值鏈優化構造的戰略基礎這一命題的研究，並以價值鏈是應對激烈競爭、改變傳統經營模式和恢復或提升競爭能力的現實要求中產生的研究結果作為引導，通過正確的解釋價值鏈的概念、結構和性質，告訴試圖應用價值鏈以解決企業經營實際問題的企業家和管理者們，價值鏈是一個將企業/事業競爭戰略與戰略實施展開的底層作業結合在一起的模式框架，所以缺失了哪一個層面的細致深入的研究而構造的價值鏈都不可能具有內在的有效性。After january, 2003, “ the law of government procurement ” came into force, both concentrative purchase and dispersive purchase are use by government, which starts an new trend of government purchase progress, using concentrative purchase to do more large quantity purchase, dispersive purchase is used less and less, it only used to do little quantity purchase. the list of government purchase has become longer and longer, the variety of materials and the quantity of materials has increased so sharply. our country ’ s government purchase has made a great progress, but but we still need to take notice of the other side of the fact, there are two important issues, the first is the obstacle of the reforming process in the field of public finance system ; and the second is the kinds of problems occurred in the process of government procurement
政府采購制度改革是我國公共財政改革的重要組成部分，引入我國從試點到推廣實施僅有十年的時間，卻取得了巨大的進展， 《政府采購法》在2003年1月開始實施后，我國採用集中采購與分散采購相結合的政府采購方式，開始了我國政府采購的集中化趨勢進程，從早期分散采購演變為大批量的集中的采購方式，當然，小批量分散采購也結合其中，列入政府集中采購目錄的物資種類與采購數量大大增加，取得了巨大的進展，卻也存在著不少的問題，具體表現為政府采購過程中出現的各種操作性問題和政府采購制度推進的障礙，以及政府采購的環境效益問題，操作性問題和政府采購制度推進的障礙問題本質上可歸納為兩方面，即內在因素，這是事前性的，偏重於制度性、體制性等根本問題;外在因素，這是管理操作層面的因素，政府采購的環境效益問題是由政府是否采購綠色產品，推動綠色產品在社會的使用而引出的，於是，對政府采購集中化趨勢中所暴露出的問題進行分析，找出問題的根源以探尋解決的思路及對策就顯得尤為急迫。After years of development, interaction characters of piles, rafts and foundations are widely applied in engineering practice. literatures on actual settlement and development process of pile - raft foundations show that substance of pile - raft foundations " settlement consists of many parts and then produces whole compressing distortion. it will take many years or even more years to finish distortion
