Abstract
Risk management is critical to the success of electric vehicle charging infrastructure public–private partnership (EVCI-PPP) projects, as risks are present throughout the whole life cycle of projects. However, in EVCI-PPP projects, risk factors are often interdependent and, consequently, the interrelationships among factors affect the risk management, which is ignored in the existing studies. To identify the risk factors of EVCI-PPP projects and analyze their internal influence relations, this paper develops a risk identification and analysis model of EVCI-PPP projects based on the 2-tuple linguistic representation model and the decision-making trial and evaluation laboratory (DEMATEL) model. First, a risk factor set is established including 22 criteria involved in 5 dimensions of political/legal risk, economic/market risk, social/environment risk, project/technical risk, and managing risk. Next, the 2-tuple model is introduced to integrate the decision makers’ evaluation information in a linguistic environment, and the direct relation matrix is calculated. Then, the cause–effect relations and a significant degree of risk factors are interpreted using the extended DEMATEL technique. The results show that economic/market risk is the most significant factor of EVCI-PPP projects, and 22 criteria are classified into 14 cause factors and 8 effect factors. Finally, suggestions are provided for decision-makers to ensure the success of EVCI-PPP projects.
Highlights
Electric vehicles (EVs) have been considered a promising technology for mitigating greenhouse gas (GHG) emissions, which have attracted the attention of countries all over the world [1,2]
It is worth noting that the imbalance of demand–supply in electric vehicle charging infrastructure (EVCI) and low charging service have become the prominent obstacles to sustainable development of EVs in China [4]

Summary
Electric vehicles (EVs) have been considered a promising technology for mitigating greenhouse gas (GHG) emissions, which have attracted the attention of countries all over the world [1,2]. In 2017, the global market share of new energy vehicles exceeded 1 million on the road. As the largest market of electric cars in terms of sales share, China has sold 556,000 electric cars, accounting for 50% globally [3]. It is worth noting that the imbalance of demand–supply in electric vehicle charging infrastructure (EVCI) and low charging service have become the prominent obstacles to sustainable development of EVs in China [4]. To deal with the issues mentioned, the public–private partnership (PPP) model has been introduced in EVCI projects to satisfy increasingly urgent charging demand by attracting private sectors to participant in electric vehicle charging infrastructure public–private partnership projects (EVCI-PPPs) [5,6]. EVCI-PPPs have the following advantages: (1) they release the government’s financial pressure and management pressure; (2) they make use of the private sectors’
