【摘要】:面對(duì)全球經(jīng)濟(jì)深度調(diào)整和能源價(jià)格劇烈波動(dòng),煤炭資源型城市產(chǎn)業(yè)生態(tài)系統(tǒng)(CCIES)的脆弱性問題已經(jīng)嚴(yán)重影響到區(qū)域經(jīng)濟(jì)的可持續(xù)發(fā)展。不論是從更好地理解一個(gè)特定區(qū)域自身CCIES的脆弱性狀況的角度,還是尋求一個(gè)有意義的基準(zhǔn)以獲得行動(dòng)方案擬定的經(jīng)驗(yàn),從區(qū)域?qū)用姹容^CCIES的健康狀況都是值得探究的。然而,針對(duì)CCIES脆弱性評(píng)估的理論和方法卻鮮有涉及,盡管這是影響CCIES綜合管理成功與否的關(guān)鍵過程。本文首先從CCIES對(duì)經(jīng)濟(jì)波動(dòng)的脆弱性響應(yīng)機(jī)理的基礎(chǔ)之上,構(gòu)建了CCIES脆弱性評(píng)估的初始指標(biāo)體系;然后采用粗糙集理論進(jìn)行屬性約簡(jiǎn)得到14個(gè)有效的指標(biāo)及相應(yīng)的權(quán)重;之后基于CCIES的綜合脆弱性評(píng)估指數(shù)(CVI),構(gòu)建粗糙集-逼近于理想解排序法-秩和比(RS-TOPSIS-RSR)模型從整體的角度對(duì)CCIES進(jìn)行脆弱性評(píng)估。運(yùn)用該模型,本文將我國33個(gè)典型CCIES依據(jù)其CVI得分進(jìn)行排序并分成3組以進(jìn)行案例分析。同時(shí)為了揭示CCIES高脆弱性存在的關(guān)鍵問題和主要成因,本文還計(jì)算了各CCIES的敏感性指數(shù)、恢復(fù)力指數(shù)和穩(wěn)定性指數(shù)。本文研究結(jié)論表明:(1)CCIES普遍呈現(xiàn)較高或高脆弱性。從時(shí)間趨勢(shì)來看,脆弱性較高的區(qū)域多數(shù)未出現(xiàn)脆弱性狀況的明顯改善,少數(shù)城市甚至脆弱性繼續(xù)增加,健康狀況明顯惡化。同時(shí),即使一些煤炭城市脆弱性程度始終較低并呈逐年下降趨勢(shì),但仍舊面臨一些問題,甚至有些問題是十分嚴(yán)峻的。(2)CCIES的脆弱性狀況存在區(qū)域差異性,產(chǎn)業(yè)生態(tài)系統(tǒng)脆弱性水平始終維持在較低水平的煤炭城市,大都分布于經(jīng)濟(jì)較發(fā)達(dá)的中國東部地區(qū);CCIES脆弱度始終維持在較高水平的煤炭城市,大都分布于經(jīng)濟(jì)相對(duì)落后的中國西部地區(qū)和東北地區(qū)。(3)CCIES的脆弱性格局成因存在差異性。無論是脆弱性較高還是較低的煤炭城市,即便有些城市的總體脆弱性程度基本一致,但其脆弱性格局的成因卻不盡相同。本研究對(duì)于完善脆弱性理論、拓展脆弱性的研究領(lǐng)域、豐富煤炭資源城市治理理論體系具有重要的理論價(jià)值,同時(shí)為政府制定政策和企業(yè)采取措施以降低CCIES的脆弱性提供決策參考。
[Abstract]:With the depth of the global economic adjustment and energy price volatility, the coal resources city industrial ecosystem (CCIES) vulnerability problem has seriously affected the sustainable development of regional economy. Whether it is from a better understanding of the vulnerability in a specific region of their CCIES point of view, or seek a meaningful reference for the action plan of the experience, from the regional level of CCIES's health is worth exploring. However, the theory and method for CCIES vulnerability assessment are rarely involved, although this is a key process of CCIES integrated management of success. This paper from the CCIES on economic fluctuation vulnerability based response mechanism on the construction of the initial CCIES vulnerability assessment index system; and then the theory of attribute reduction are 14 effective index and the corresponding weight matrix after rough set; Comprehensive vulnerability assessment index in CCIES (CVI), constructing rough set TOPSIS method of rank sum ratio (RS-TOPSIS-RSR) model for vulnerability assessment of CCIES from overall perspective. Using this model, the 33 typical CCIES in China on the basis of the CVI scores are sorted and classified into 3 groups to case analysis. At the same time in order to reveal the main causes and key problems of CCIES high vulnerability, the paper calculates the sensitivity index CCIES, resilience index and stability index. The conclusions of this study show that: (1) CCIES generally higher or high vulnerability. From the time trend, most of the region more vulnerable there is no obvious improvement of fragility, vulnerability and even a few city continues to increase, health deteriorated significantly. At the same time, even if some of the coal city vulnerability degree has remained low and showed a declining trend, but still face Facing some problems, even some of the problems are very serious. (2) the vulnerability in CCIES has regional differences, industry ecosystem vulnerability level has remained at a low level of the coal city, mostly located in the economically developed eastern region China vulnerability; CCIES is always maintained at a high level in the coal city. Most of the distribution in the economy is relatively backward Chinese western and northeastern regions. (3) the causes of the existence of CCIES weak character Bureau differences. Both the fragility of higher or lower coal city, even some of the city's overall degree of vulnerability is basically the same, but its weak pattern causes this study is not the same. To improve the fragility theory, expand the research field of fragile, abundant coal resources city governance theory has important theoretical value, and take measures to reduce for the government and enterprises The vulnerability of low CCIES provides a decision reference.
