【摘要】:棕色土地(Brownfield)是指存在一定程度污染,因而沒有得到充分利用的土地及地上的建筑物。成功再開發(fā)這些無人管理、臟亂、逐漸失去利用價值的棕色土地可以提高當(dāng)?shù)鼐用裆钏剑阑?dāng)?shù)丨h(huán)境,緩解城市用地緊張,促進(jìn)當(dāng)?shù)氐纳鐣?jīng)濟(jì)發(fā)展。 棕色土地再開發(fā)是一個復(fù)雜的投資項目,它涉及到了社會、生態(tài)、環(huán)境等系統(tǒng),蘊含了大量的不確定性和高風(fēng)險性,要在不確定的環(huán)境中進(jìn)行投資決策,需要一套有效合理的評估方法。傳統(tǒng)的項目評估方法主要代表是現(xiàn)金流量折現(xiàn)法,它的優(yōu)點在于考慮了時間價值,可以有效地評估短期、小型的投資項目,但是在評估具有高風(fēng)險性、高不確定性的棕色土地再開發(fā)投資項目時,它忽略了項目投資決策的彈性,不能有效地處理項目開發(fā)過程中的不確定性,從而低估了項目的價值。 實物期權(quán)法是現(xiàn)今企業(yè)決策分析領(lǐng)域中最重要的發(fā)展之一,它能夠充分考慮到投資決策的彈性以及期權(quán)的價值。B-S期權(quán)定價模型假定,未來現(xiàn)金流入現(xiàn)值S和投資總成本X兩個參數(shù)是確定的值,但是棕色土地再開發(fā)投資項目是高風(fēng)險的、不確定的,,因此這樣的假定是有有一定的局限性。在B-S期權(quán)定價模型的基礎(chǔ)上,以棕色土地再開發(fā)項目的投資決策為研究對象,針對項目中未來現(xiàn)金流入現(xiàn)值和投資總成本的不確定性,結(jié)合模糊數(shù)學(xué)理論,引入模糊數(shù)建立了模糊實物期權(quán)定價模型。并通過案例,分別運用傳統(tǒng)評估方法NPV和模糊實物期權(quán)法對其進(jìn)行了投資決策分析,同時運用Crystal Ball風(fēng)險評估軟件進(jìn)行蒙特卡洛模擬仿真。案例分析表明在不確定的投資環(huán)境下,相較于傳統(tǒng)投資決策方法,使用模糊實物期權(quán)法進(jìn)行投資決策,更具科學(xué)性,具有較大的理論意義和實用價值。
[Abstract]:Brown land (Brownfield) refers to land and buildings that are not fully used because of a certain degree of pollution. Gradually losing the value of brown land can improve the living standard of local residents, beautify the local environment, ease the shortage of urban land, and promote the local social and economic development. Brown land redevelopment is a complex investment project, which involves social, ecological, environmental and other systems, contains a lot of uncertainty and high risk, to make investment decisions in an uncertain environment. A set of effective and reasonable evaluation methods are needed. The traditional project evaluation method is mainly represented by the cash flow discounted method, which has the advantage of considering the time value, and can effectively evaluate short-term, small investment projects. However, in the evaluation of high-risk and high-uncertainty brown land redevelopment investment projects, it ignores the flexibility of project investment decisions, and can not effectively deal with the uncertainty in the process of project development. This underestimates the value of the project. The real option method is one of the most important developments in the field of enterprise decision analysis. It can fully consider the elasticity of investment decision and the value of option. B-S option pricing model assumption. The present value of future cash inflow S and the total cost of investment X are determined values, but brown land redevelopment investment projects are risky and uncertain. On the basis of B-S option pricing model, the investment decision of brown land redevelopment project is taken as the research object. In view of the uncertainty of the present value of future cash inflow and the total cost of investment in the project, a fuzzy real option pricing model is established by introducing fuzzy numbers in combination with fuzzy mathematics theory. The traditional evaluation method NPV and the fuzzy real option method are used to analyze the investment decision. At the same time, Monte Carlo simulation is carried out by using Crystal Ball risk assessment software. The case analysis shows that in the uncertain investment environment, compared with the traditional investment decision-making method. The fuzzy real option method is more scientific and has great theoretical significance and practical value.
