摘要

目的本研究旨在评估加纳公私合作（PPP）电力项目固有的关键风险因素，并进一步确定PPP电力项目中影响公共和私营部门的关键风险因子。设计/方法/方法两轮排名式德尔菲调查，建立PPP关键风险因素的综合列表。目的性和滚雪球抽样技术帮助德尔菲调查获得了专家。采用平均分排序、因子分析、Cronbachα系数和Kendall一致性进行分析。计算每个风险因素的发生概率和严重程度，以获得风险影响。发现在67种风险的列表中，37种风险因素被认为是关键的。五个最重要的风险因素是：合同延期付款、私人投资者变更、政治风险、发电需求波动和公众反对。主成分分析将风险因素分为七个主要主题。独创性/价值本研究为PPP电力项目制定了一份权威的风险因素清单，该清单反映了优先考虑和减轻风险因素的行业和国家条件。本研究中采用的德尔菲方法可用于未来类似环境中的研究，在类似环境中，购买力平价是新颖的，专家受访者很少。

Delphi study for evaluating key risk factors inherent in public-private partnership (PPP) power projects in Ghana

Purpose This study aims to evaluate the key risk factors inherent in public–private partnership (PPP) power projects in Ghana and further determine the critical risk factors affecting both the public and private sectors in PPP power projects. Design/methodology/approach Ranking-type Delphi survey in two rounds was conducted to establish a comprehensive list of critical risk factors of PPP. Purposive and snowball sampling techniques helped obtain experts for the Delphi survey. Mean score ranking, factor analysis, Cronbach α coefficient and Kendall’s concordance were used for analysis. The probability of occurrence and severity of each risk factor were computed to obtain the risk impact. Findings From the list of 67 risks, 37 risk factors were deemed to be critical. The five topmost risk factors were: delay payment on contract, private investor change, political risks, fluctuating demand of power generated and public opposition. Principal component analysis grouped the risk factors into seven major themes. Originality/value This study develops an authoritative risk factor list for PPP power projects, which reflects both sector and country conditions for prioritizing and mitigating risk factors. Delphi approach adopted in this study can be used by future studies in similar environments where PPP is novel and expert respondents scarce.
