【正文】 加速發(fā)展的新形勢，起著積極的促進(jìn)作用。因此本項(xiàng)目建設(shè)符合高新區(qū)拓展區(qū)控制規(guī)劃的相關(guān)要求。高新區(qū)拓展區(qū)東接中梁山西麓和襄渝鐵路，西鄰***市繞城高速路西段，北接沙坪壩曾家、西永微電園、寨山坪，南至走馬、三多橋、巴福一線。但是，隨著企業(yè)發(fā)展規(guī)模的壯大，用地需求也越來越大，原規(guī)劃的 20 平方公里用地已經(jīng)用完，相關(guān)企業(yè)已經(jīng)沒有進(jìn)一步發(fā)展的空間。綜合經(jīng)濟(jì)實(shí)力西部領(lǐng)先：地區(qū)生產(chǎn)總值達(dá)到 566 億元，工業(yè)產(chǎn)值占全市的比重穩(wěn)定在 5%左右。集團(tuán)公司致力于把市場經(jīng)濟(jì)要素引入城市建設(shè)與管理，不斷追求社會效益、環(huán)境效益和經(jīng)濟(jì)效益三者的協(xié)調(diào)統(tǒng)一；堅(jiān)持“責(zé)任、意識、勤奮、高效”的經(jīng)營方針，主要業(yè)務(wù)包括對基礎(chǔ)設(shè)施建設(shè)、土地開發(fā)、房地產(chǎn)開發(fā)、現(xiàn)代產(chǎn)業(yè)體系構(gòu)建和高新科技成果轉(zhuǎn)化等進(jìn)行投資、建設(shè)、管理和資本運(yùn)作，進(jìn)行土地儲備整治等。1高新區(qū)市政道路可行性研究報(bào)告目錄概述
