Social Risk Assessment and Management for Major Construction Projects in China Based on Fuzzy Integrated Analysis

. With the vigorous development of major engineering projects in China, the social risks associated with major construction projects not only challenge the success of projects but also threaten social harmony and stability. Therefore, it is of great practical significance to assess and manage social risks. This paper aims to identify and evaluate the social risk factors by conducting a survey and assess the overall risk level of major construction projects (MCPs) with fuzzy integrated approach. First, 35 social risk factors and related stakeholders were identified based on literature analysis and case study. Then, 18 critical social risk factors (CSRFs) were selected and classified into six groups (CSRGs) based on a questionnaire survey. Next, using fuzzy integrated method, the probability of occurrence (PO), magnitude of impact (MI), the integrated risk level (IRL) of each CSRF and CSRG, and the overall risk of MCPs were calculated. As a result, “unfair compensation for housing demolition and land requisition” was the most critical social risk factor, and “policy/legal risk” was the most critical social risk group. The overall risk of MCPs was between moderate and high. At last, a social risk synthetic management framework was established, which can provide reference for policymakers and project decision makers to effectively manage the social risks.


Introduction
MCPs (major construction projects) are generally public welfare projects invested by the government, and they have signi cant impacts on the economy, society, environment, security, and safety of wide regions or even the entire country [1].In recent decades, major construction projects such as South-to-North Water Transfer Project, Beijing-Shanghai High-Speed Railway, Hangzhou Bay Bridge, and Hong Kong-Zhuhai-Macao Bridge have been carried out in China.
Nevertheless, when compared with common projects, MCPs are usually large scale, have long time span, and have wide space scale, involving high levels of complexity and uncertainty.In the life cycle of a project construction, it often involves immigration, land acquisition and demolition, environmental pollution, which can a ect and destroy the traditional lifestyle and living environment, and interests of local farmers.e con icts among local governments, managing sectors, and the a ected people constantly occur [2].Without e ective management and decision-making, the con icts among stakeholders have become more predominant and subsequently will result in grave consequences, such as increasing disposal costs, economic loss, cancelation, or postponement of the projects.Even worse, community petitions and incidents, originated in serious con icts, will a ect social stability seriously.A case of this negative in uence is the "10 • 14 Incident": on October 14 th , 2014, a massive violence exploded between construction personnel and local residents in Jinning County, Yunnan Province, resulting in eight deaths and 18 injured [2].e con ict was caused by the construction of "Pan-Asian Industrial Products Trade and Logistics Center Project" mainly because villagers believed that their interests were seriously damaged and the original compensation plan could not meet their needs.Another mass emergency happened in Qidong City, Jiangsu Province.On July 28 th , 2012, the local people occupied the municipal government buildings which caused a certain negative impact on the society.e incident was triggered by the approval of the Nantong Municipal Government of Jiangsu Province for the paper-making and sea-discharging project of the Prince of Japan.ese conflicts showed that the megaprojects have become the intersection of social contradictions in the new period of our country.erefore, it is a must to carefully analyze social risks, including the identification, estimation, and management of risk factors and related stakeholders, based on which social risks can be mitigated and controlled in a proper manner [3].
Social risks are product of social development and modern civilization.In the Chinese context, social risks come from the conflicts of interest among different stakeholders and are typically associated with mass incidents, violent resistance, and social conflicts [4].Kasperson et al. [5] indicated that risks could be socially amplified when risk events interact with psychology, society, and culture.Improper handling of social problems will endanger social stability.e central government of China has also attached great importance to the harmonious and stable development of society.Social risks cannot be fully eliminated, rather, it can be effectively managed to mitigate the negative impacts [6].
To assess the social risks for MCPs and mitigate negative impacts correspondingly, social risk assessment framework needs to be established.erefore, we investigated large hydraulic engineering projects in China through a questionnaire survey, identified critical social risk factors, established a social risk fuzzy assessment framework, and assessed the overall social risk level.
e results can aid decision makers in decreasing a project's risk exposure and promote the sustainable development of the project and the society.
is paper is organized as follows.Section 2 provides a literature review on social risks and stakeholder management for major construction projects.Research framework is presented in Section 3, followed by the identification of the social risks and stakeholders of MCPs based on the analysis of case studies and questionnaire surveys in Section 4. In Section 5, after calculating the PO, MI, and IRL of each CSRF and CSRG, a social risk evaluation framework is presented with fuzzy approach.Finally, a social risk management framework is established to effectively manage the projects.

Literature Review
Project risk is commonly defined as an uncertain event or condition that, if it occurs, has a positive or negative effect on one or more project objectives [7].e prevailing definition of risk in the social field is defined as uncertain and serious events or consequences due to a certain valuable activity [2,8].Risk is inherent in every ongoing project.e identification and estimation of risk is the key element in the risk management process [9].
To comprehensively and systematically assess the risks of construction projects, many approaches have been applied, such as AHP [1,10], fault tree analysis [11], and expected utility [12].Recently, many risk assessment approaches have been used based on linguistic terms (such as low probability and high risk) instead of numerical values.
ese terms cannot be defined with an exact single value, but fuzzy set theory provides the means by which these terms may be formally defined in mathematical logic [13].Samantra et al. [5] proposed a risk assessment model for metropolitan construction projects based on fuzzy theory.e authors identified 20 risk factors related to design, management, safety, natural hazards, social, and economy and ranked the critical risk factors.Zhang et al. [11] presented a probabilistic decision approach for safety risk analysis for metro construction and proposed an expert confidence index for the fuzzy probability estimation of basic events.Using fuzzy AHP, Nieto-Morote et al. [13] presented a risk assessment of a rehabilitation project of a building.Bavafa et al. [14] also identified and assessed the causal relationships of safety program factors in the construction projects in Kuala Lumpur using Fuzzy Delphi Method and DEMATEL.Taylan et al. [15] attempted to select the project through the combination of fuzzy AHP and fuzzy TOPSIS theory.Kou and Lu [16] employed fuzzy AHP to evaluate the risk for a metropolitan construction project.
ey also used the consistent fuzzy preference relations (CFPR) method for relative impact assessment.Xu et al. [17] proposed a fuzzy synthetic evaluation model for assessing the overall risk of highway construction PPP projects in China.Using fuzzy DEMATEL-ANP, Mavi and Craig [18] identified critical success factors of sustainable project management in construction.
e aforementioned research studies mainly involved cost overruns, quality problems, overtime, etc.However, with the progress of society, people have higher requirements for projects, not only focusing on traditional risks (e.g., time planning and cost control), but also on the social performance of projects (e.g., environment, sustainable development, and harmony with the people).Recently, social risk has become a hot topic.From the qualitative perspective, Zhang [19] identified the key social risk factors associated with international contractors from a questionnaire survey and a case study; Liu et al. and Shi et al. [2,20] explored how to identify and manage social risks and developed response plans to prevent, mitigate, and cope with the potential consequences of social risk events that may occur before or during the implementation process.
Research studies on social risk are mainly based on Baker's [21] research on "Risk."Social risk can be understood as the challenges faced between stakeholders and companies on the social consequences of their business practices [3].Social risk has diverse meanings in different disciplines and society backgrounds.In the Chinese background, social risk owns its specified implication and particularly refers to those group events (such as public confrontation, open protest, and violent conflict) due to the conflicts of interest among different stakeholders [2].Based on indigenous analysis of construction projects in China, Xiang and Luo [22] indicated that social stability risk can be prevented and resolved by reducing risk source and preventing risk pathway.Based on the vulnerability of the social 2 Complexity system, Huang et al. [23] proposed a social risk assessment model of a large hydraulic construction that consists of social risk exposure and public risk perception.Social risk management is characterized by a systematic process of identifying and classifying, analyzing and assessing, responding, and controlling risks [24,25].Holzmann and Jørgensen [26] constructed a social risk management framework.
is framework aimed to help individuals, families, and communities manage social risks and provided support to the critically poor.ey proposed that social risk management included prevention, mitigation, and coping strategies.
erefore, from this point of view, social risk management is closely related to stakeholder management.
Using a social network analysis, Yuan et al. [3] established an improved analysis model of social risk for construction projects in high-density urban areas, considering the interrelationships between stakeholders and risks.For large hydraulic engineering projects, He et al. [27] investigated the relevant risk factors and considered the relationships among stakeholders and their linkages of risks based on social network analysis.By systematic literature review on the current construction literature, Xia et al. [25] put forward that integrated management of construction risk and stakeholder is feasible and can promote the effectiveness of management.
In summary, the study of social risk is still in its infancy, and the existing work on this research area had some deficiencies.First, the existing assessment model did not evaluate the overall social risk for MCPs.Second, the previous social risk model did not consider fuzziness within the projects.Since risk assessments in MCPs are often multilayered and fuzzy in nature, which require evaluators' subjective judgment, it is appropriate to adopt fuzzy theory to establish a fuzzy risk assessment model for MCPs [17].Taking into account the features of MCPs, this paper established a social risk fuzzy assessment model for assessing the risk level of CSRGs and the overall risk level of MCPs in China.

Research Framework
Risk analysis is the process of identification, analysis, and response, either the acceptance or mitigation of uncertainty in decision-making [28].In this paper, large hydraulic engineering projects are selected as illustration cases for developing a social risk evaluation model.
Research framework is presented in Figure 1. e research frame includes the following: (i) Identify social risk factors through cases analysis and a wide literature survey, and then select the critical risk factors through a two-round questionnaire survey and expert judgments.(ii) Assess social risks based on fuzzy integrated analysis technique.(iii) Establish a social risk management structure combined risk management with stakeholder management.

Identification of Social Risk Factors and Stakeholders
In this section, first, we identified the underlying social risk factors and stakeholders through case studies and literature reviews.Second, by means of a questionnaire survey and face-to-face interviews, after investigating large hydraulic engineering projects in China, CSRFs were selected and classified.

Underlying Social Risk Factors and Stakeholders with Case
Study. e case study analysis can provide effective means to identify and understand factors that contribute to the failure of the studied projects.In this section, we selected 15 conflict incidents from years 2005 to 2018 by web search according to the following criteria [3]: (1) e case must be a major construction project (2) e case must be related to social risk events (collective conflicts) (3) e case should not be out of date (not a long time away from the day of case collection) e social risk factors and stakeholders (see Table 1) are identified by a study group discussion.

Social Risk Factors and Stakeholders with Literature
Analysis.In this section, through wide-ranging literature resources, following the discussion of the project team, the social risk factors and related stakeholders were summarized.A primary list of 33 risk factors were obtained and identified as shown in Table 2.

Determining CSRFs.
In this section, to identify CSRFs and effectively determine the evaluation criteria, we conducted a two-round questionnaire survey for data collection, and this method has been used in project risk analysis [21,29,31].e detailed steps are summarized as follows: Step 1. Experts' selection.
In order to obtain reliable data and to limit subjectivity, we selected experts who satisfied at least one of the following criteria: (1) Experts who have extensive experience within construction projects of China (2) Experts who have been involved in at least one project, with in-depth knowledge of risk management in construction project in China or have gained abundant knowledge about risk management through research Step 2. Questionnaire dissemination and data analysis.
A two-round questionnaire survey was conducted.In the first round of the questionnaire survey, we designed a structured questionnaire consisting of two parts: (1) thirtythree potential social risk factors, and each risk factor has been described by (i) probability of occurrence (PO) and (ii) magnitude of impact (MI) based on a 7-point Likert scale ( rough the online questionnaire and personal interviews, we distributed questionnaires and asked experts to answer the questions according to their own knowledge and experience.As a result, the new added risk factors were "media dissemination" and "decision-maker moral". In the second round, experts were invited to check on updated risk factors and reconsider their estimation about OP and MI of each risk factor.A total of 28 questionnaires were sent out, and feedback from 16 experts (see Table 3) was received, yielding a response rate of 57%.It was supposed to be satisfactory for the purposes of this research.
In addition, face-to-face interviews were also conducted with 26 stakeholders in a certain village, where more than one hundred inhabitants live.
ese semistructured interviews posed some questions regarding social risk factors (see Appendix B). e results will help us examine and identify the social risk factors.
At last, in order to ensure the validity of questionnaire data, questionnaires should be subjected to statistical analysis to con rm their reliability and validity [19,30].Cronbach's alpha coe cient is the most commonly used at present.If the Cronbach's alpha coe cient is higher than 0.7, the reliability of the questionnaire data would be proven [14,30].Based on SPSS software, the Cronbach's alpha values of probability and severity of the data used in this study were calculated to be 0.962 and 0.967, respectively, indicating that the risk factors showed high internal consistency and that the questionnaire was reliable.
Step 3. Ranking social risk factors.
According to the information from experts, we calculated the average score of PO and MI of each risk factor, and the integrated risk level (IRL) (IRL PO × MI √ ) and ranked them based on IRL values in descending order, and then, normalizing corresponding IRL with equation ( 1). e results are shown in Table 2.
where y i is the value of IRL (see  Step 4. Determining CSRFs. We consider the risk factors with normalized integrated risk value equal to or greater than 0.50 as critical factors.is selection mechanism follows a similar approach adopted in the previous study [21,28,29,31].In this way, 18 factors were chosen for the following analysis, and they were classified into four categories (see Table 4).

Social Risk Assessment with Fuzzy Synthetic Theory
5.1.Fuzzy Synthetic Assessment (FSA) Method.Fuzzy set theory, which was introduced by Zadeh in 1965, defines fuzzy numbers that have the ability of quantifying subjective linguistic terms (such as very rare, rare, low, moderate, frequent, very frequent, and absolutely certain).FSA, which combines fuzzy theory with the multiple attribute decisionmaking method, is a branch of fuzzy set theory and can effectively handle the fuzziness of data involved in decisionmaking [28].In recent years, the fuzzy synthetic assessment method is widely employed in risk assessment.Xu et al. [21] determined 17 critical risk factors and six critical risk groups for PPP projects in China through a questionnaire survey and developed a risk synthetic assessment model.With FSA method, Ameyaw and chan [32] assessed the overall risks of public-private partnership water supply projects in developing countries and confirmed that financial/commercial risk category is the most critical principal factor.Wu et al. [31] explored risk factors for straw-based power generation public-private partnership projects in China through a questionnaire survey and evaluated the risk level using the FSA method.Despite the wide applications, it is rare in the literature to assess the social risk of MCPs under uncertain conditions; FSA is an effective method to handle this problem.

Social Risk Synthetic Assessment Based on Fuzzy eory.
In this section, in order to assess the overall social risk level for MCPs, large hydraulic engineering projects were selected as illustration cases for developing a fuzzy risk evaluation model.e detailed steps are summarized as follows.

Quantification of Language Variables for the CSRFs.
According to fuzzy theory, the linguistic information can be translated into appropriate fuzzy numbers.erefore, we quantified experts' linguistic terms (such as absolutely low, very low, low, moderate, high, very high, and absolutely high) through the following equation (see [21,31,32]): where d ij denotes the jth risk factor of the ith(i � c 1 , c 2 , . . ., c 6 ) CSRG; MF d ij represents the membership function of a certain risk factor d ij ; and x kd ij (k � 1, 2, . . ., 7) is the percentage of the experts who scored j for PO and MI of the risk factor d ij , which is the degree of membership function.Equation (2) can also be written as follows: and MF d ij satisfies  7 k�1 x kd ij � 1.For example, MF pd 11 � (0, 0, 0.125, 0.125, 0.5, 0.0625, 0.1875) represents the membership function of a certain risk factor d 11 regarding PO.We defined the weightings for each of the 18 CSRFs and 6 CSRGs using the following equation: where ω i denotes the weighting function of a particular CSRF or CSRG concerning the PO and MI; m i represents the mean value of a CSRF or CSRG from the questionnaire; and x is the number of elements.e weighting vector can be expressed as follows: Results are shown in Table 5.

Establishment of Social
Risk FSA Model. is section consists of three steps.
e first step deals with the assessment on the intragroup factors.e second step deals with the assessment on the intergroup factors.e third step deals with the overall risk assessment on the project.
Step 1.According to equation ( 2), the fuzzy degree of membership matrix regarding ith CSRGs (probability or severity) is written as follows: en, the fuzzy assessment matrix F c i can be obtained using the weighting vector and the membership function of the CSRFs within a CSRG to do fuzzy synthesis computation: where f in is the degree of membership of the ith CSRGs and the symbol "•" is the fuzzy composite operation (see [21,29,32]), and it can be represented by the following formula: Results are shown in Table 6.
Step 2. e following evaluation matrix can be obtained: Similarly to Step 1, we can obtain S that can assess the overall project social risk: where S is the degree of membership of the overall social risk of project regarding risk probability (p) or impact level (l), and it can be quantified by using the following equation: Results are shown in Table 7.
Step 3. We obtained not only the integrated risk index of each risk group, but also the overall risk index of the project using equation (12).Moreover, we can rank CSRGs according to IRL index (See Table 8);

Conclusion of Social Risk FSA Model.
rough wideranging literature resources and case studies, we identified 35 social risk factors and related stakeholders.After a questionnaire survey and calculation of the probability and impact for risk factors, 18 critical social risk factors were determined and were classified into six groups (CSRGs), that is policy/ legal (c 1 ), society (c 2 ), environment (c 3 ), finance (c 4 ), project/ technique (c 5 ), and organization/management (c 6 ).
As seen from Table 2, unfair compensation for housing demolition and land requisition ranked the top with score 5.25 that was between "high" and "very high".It was followed by poor credibility of government, forced demolition, engineering quality problems, violation of laws and rules, disturbance of local residents, government's improper administration, unreasonable relocation, and security hidden danger.e IRL of these risks is greater than 4.6, and they need to be specially noticed.Moreover, these factors have already been discussed and considered as the most crucial risk factors for construction projects in some literatures (see [3,4,18]).Liu et al. [2] pointed out land acquisition and house demolition risks (such as unfair land acquisition compensation standard, compensation supporting measures, demolition compensation standard, and unreasonable resettlement arrangement) were high social risk factors.e results implicated both governments and decision makers should have paid more attention to the top 10 risk factors.e summary results of social risk FSA are shown in Table 7 which manifested the mean value of probability and severity, the IRL of critical risk groups, risk ranking, and the overall project risk index.From Table 7, we can obtain the overall risk index of the MCPs in China as 4.65, which is between moderate and high.As for the risk groups, the policy/legal risk ranked first with an integrated risk rating of 5.2, which is high risk.e following CSRGs are project/ technique, environment, society, finance, and organization/ management with the overall risk index 4.93, 4.76, 4.54, 4.51, and 4.47, respectively.In summary, the overall social risk level of the MCPs in China is slightly higher.e policy/legal risk and project/technique risk are high.

Comparison Analysis.
In order to explore the additional results of fuzzy logic, a comparison analysis between the results obtained by the fuzzy logic and the results of Table 2 was conducted.e detailed steps were summarized as follows.Complexity 9 Step 1. Weighted membership.
Step 3. IRL calculation and rank.
Results are shown in Table 9 and Figure 2.
In Table 9, rank of factors of the two models is listed.We can see that the risk rankings have slightly changed.e  In part, it is because they have relatively larger weighting.erefore, these factors should be paid more attention.e order of six factors decreased.e order of four factors is the same as before.

Complexity
As is shown in Figure 2, of the top 10 factors, the top nine are the same, only the tenth is di erent.In a word, the social risk factors always keep the ranking in closeness no matter how the addition of fuzzy logic.It shows that the addition of fuzzy logic have slightly impacts on the results of the risk ranking.

Social Risk Synthetic Management Framework in MCPs
In this section, we proposed the strategies to mitigate the social risks from the perceptive of both risk management and stakeholder management.Social risk management framework is shown in Figure 3.

Risk Factor Management
6.1.1.Policy/Legal Risk.Unfair compensation for housing demolition and land requisition, forced demolition, violation of laws and rules, unreasonable relocation, and variations in policies or compensation standards are risk factors that need to be watched out due to higher mean value.ese risk factors are all related to land expropriation and house demolition.Government, residents, contractor, and supervisor are the critical stakeholders.In response to these risk factors, rst, the local government should work out a speci c compensation and resettlement proposal to clarify principles for interest protection of a ected villagers under the guidance of a series of laws and regulations.At the same time, the administrative department must be fair and impartial and avoid fraud for personal gain.Second, local cadres may indulge into residents' families for information gathering in order to understand the speci c requirements, correct misunderstandings, and mitigate possible risks.Finally, to avoid violence, the superior departments also need to formulate policies to regulate the behavior of lower departments in order to prevent illegal incidents.

Society and Environment Risk.
Poor credibility of government, disturbance of local residents, environment pollution (water, land, noise, etc.), negative attitudes of local residents towards project, media dissemination, and unemployment problems are critical risk factors.First of all, to gain the trust, the government should publicize information regarding project (such as time frame, construction site, project usage, etc.), environmental impact assessment report, land requisition and house demolition compensation program, and resettlement plan by using various channels such as television, Internet, and notice boards in villages.On the other hand, from the previous analysis, we know that environmental pollution is an important factor leading to con icts.erefore, the construction party should take measures to protect the environment and minimize the impact on surrounding environment in accordance with the environmental protection policy.For example, the construction party can reasonably stack and dispose o construction wastes, purify the exhaust gas using the bag lter, and reduce noise pollution.Meanwhile, the supervisory authorities should also earnestly ful ll their responsibilities and obligations.Finally, to vulnerable group issues, governments and developers may organize re-employmenttraining programs to get new jobs.
6.1.3.Finance Risk.Lack of funds is also an important factor which may lead to social risks.e funding issues not only a ect project quality and schedule, but also in uence allocation of funds and compensation funds which can easily lead to discontent and con ict among residents.erefore, to ensure adequate funds, the government should make 12 Complexity detailed plans to allocate funds.Various investment modes such as public-private partnership, build-operate-transfer, and build-transfer can be adopted to attract large companies with sufficient funds to participate in projects.
6.1.4.Project/Technique.Engineering quality problems are related to people's lives and safety.e loss caused by engineering quality accidents is shocking.Quality accidents not only involve the interests of the main body of the construction market, but also affect the stability and development of the construction market.In response to this risk factor, the public sector should improve the engineering quality policy.For quality accidents caused by illegal acts, the responsible persons should be severely punished.Establishment of the scientific evaluation system and operation mechanism of government supervision, and the further standardization of government law enforcement can fundamentally guarantee the benefits of construction project quality.
6.1.5.Organization/Management. Government's improper administration, security hidden danger, lack of information on key stakeholders' interests, and decision-maker competence and moral deserve attention.Above all, the government should recognize its responsibilities and should not interfere too much the owners and contractors.Next, stakeholders should exchange information regularly to avoid the uncertainty caused by information asymmetry.Only by strengthening exchanges and cooperation among key stakeholders can the project proceed smoothly.At the same time, the trust relationship between the government and the local residents should be established to avoid contradictions.irdly, managing sectors should strengthen safety awareness and always put production safety in the first place in the life cycle of a project.At last, managers should not only strengthen the study of professional theoretical knowledge and improve their management ability, but also strengthen their social responsibility.

Stakeholder Management.
According to Yang et al. [33,34], successful stakeholder management can start from five aspects.

Social Responsibilities.
Managing stakeholders with social responsibilities (economic, legal, environmental, and ethical) is the premise of stakeholder management and the most important for the success of stakeholder management [34][35][36].According to Carroll [37], economic responsibility is the obligation to produce goods and services, sell them at reasonable prices, and gain benefits; legal responsibility is the obligation to obey laws and regulations; and ethical responsibility contains those aspects not included in laws but expected by society.Environmental issues involve air, dust, water, land and noise.e purpose is to protect the environment and to provide healthy living conditions [15].In fact, no matter internal stakeholders or external stakeholders, if they all consider and solve problems from the perspective of social responsibility, any conflicts and contradictions will be solved smoothly.erefore, the primary task of stakeholder management is to manage the social responsibility of stakeholders.

Information Gathering.
is part mainly includes the identification of stakeholders and the exploration of their interests and needs.
e effective method for identifying stakeholders includes personal past experience, snowball sampling, guidelines from governments or one's own organization, and professional services [33].Personal past experience and snowball method are the most effective and commonly used.In Section 4, we determined the stakeholder related to social risk factors using the two methods.As for the exploration of their interests and needs, decision makers can communicate with key stakeholders through interviews and meeting methods.

Stakeholder Analysis.
Decision makers need to comprehend the attributes and behavior of stakeholders, the impact on projects and conflicts and alliances between them.Communication and personal past experience is still important for gathering information about stakeholders.e other effective methods, such as focus groups, questionnaires, public engagement, and interviews, may also reveal preliminary issues that are of concern to a group or community.

Decision-Making.
Resolving conflicts, developing suitable strategies, and predicting stakeholder responses are very important.If the conflicts among local governments, managing sectors, and the affected people cannot be effectively resolved, it will result in grave consequences.Even worse, community petitions and incidents originated by serious conflicts will affect social stability seriously.erefore, decision makers not only need to formulate effective strategies, but also need to pay attention to the dynamic response of stakeholders.Meetings and workshops were regarded as the most common ways of implementing decisions.Negotiations can also be categorized as communication with stakeholders, especially when settling disputes and problems [33].6.2.5.Sustainability.At last, in order to maintain the sustainability and effectiveness of stakeholder management, decision makers should also pay attention to the impact and changes of stakeholders, maintain communication with stakeholders properly and frequently, and keep a stable relationship.

Conclusion
In recent decades, with the rapid social development, major construction projects have become the driving force of social economic development, but at the same time, land acquisition, housing demolition, and environmental damage can affect and destroy living environment and interests of local farmers.
e conflicts among local governments, managing sectors, and the affected people constantly occur.erefore, it is Complexity 13 urgent to carefully analyze social risks associated with MCPs, including the identification, estimation, and management of risk factors and related stakeholders, based on which social risks can be mitigated and controlled in a proper manner.is paper identified 35 social risk factors and stakeholders of major construction projects in China by wideranging literature resources and case studies.After a questionnaire survey and calculation of the probability and impact for risk factors, 18 critical social risk factors were determined and were classified into six groups (CSRGs), that is, policy/legal, society, environment, finance, project/ technique, and organization/management. en, a fuzzy synthetic analysis model was established to assess the overall social risks for MCPs.As a result, the overall risk level of MCPs in China is 4.65, which is between moderate and high.As for SCRGs, the policy/legal risk ranked first with an integrated risk rating of 5.2, which is high risk, followed by project/technique, environment, society, finance and, organization/management with the risk index 4.93, 4.76, 4.54, 4.51, and 4.47, respectively.
In terms of practical implications, these findings can assist managing sectors in managing and mitigating social risks in the life cycle of a construction project.First, the 35 social risks identified helps practitioners to better understand the underlying social risks, and the 18 critical social risks can be referred as a checklist for managers to identify risks and develop risk-response plans in MCPs.Second, the FSA model established in this study can be used to evaluate the overall risk level of MCPs, and this result can help policymakers understand risk levels in general.At last, the integrated framework model for risk management can help manage risks and reduce the negative impacts of social risks in MCPs.their probability of occurrence and magnitude of impact.
