| With the acceleration of urbanization process,mega construction projects play an indispensable role in meeting residents’ living needs,improving urban carrying capacity and developing a sustainable society.Although the planning and construction of mega construction projects is the entry point of national economic and social investment as well as the key point of social development,it is also the trigger point of social conflicts.However,traditional ways of social management can not respond to the social conflicts caused by mega construction projects,the strategies for improvement of public acceptance are essential for the development of mega construction projects.Therefore,effectively improving public acceptance on mega construction projects is a new contradiction that must be faced and solved in the process of China’s modernization.At present,the research on public acceptance is relatively comprehensive,but few scholars have linked different types of mega construction projects for comparative analysis,and studies on the interaction mechanism of perceived benefit and perceived risk on public acceptance is also relatively scarce.This research selects GS Substation and Stage II of Metro Line N as the comparative cases.Firstly,through the stratified sampling method and face to face questionnaire survey to collect the public acceptance data,and combine empirical analysis,structural equation model,as well as other research methods to set up a social cognitive theory model;Secondly,through reliability analysis,validity analysis and hypothesis test,this paper explores the influencing factors of public acceptance on mega construction projects and the differences of their internal mechanisms.Finally,based on the findings,this study formulates the public acceptance promotion strategy,reconstructs and optimizes the government decisionmaking mechanism.The structural equation model based on social cognitive theory is used to qualitatively and quantitatively analyze the survey data of mega construction projects,and explore the interaction mechanism between the observed variables and four latent variables.The results of this study show that:(1)Through the comparation between public acceptance on GS Substation and Stage II of Metro Line N,this research finds that there are significant differences in the acceptance degree on different mega construction projects.For the projects with greater benefits,the public is willing to accept,while for the projects with greater risks,the public shows strong opposition;(2)There are two dimensions that influence public acceptance on mega construction projects-internal driving force and external driving force.Internal driving force includes self-efficacy and perceived benefit-risk,while external driving force includes social environment;(3)There are significant differences in the determinants of public acceptance on mega construction projects and their internal mechanism.The direct effect of self-efficacy on public acceptance on mega construction projects that with larger negative externalities is ineffective,but it has a significant direct influence on public acceptance on mega construction projects with more benefits.Social environment has significant direct and indirect influence on behavioral patterns;(4)In addition to the direct effect of perceived benefit-risk on public acceptance,the perceived benefit-risk also affects public acceptance as the mediating factor of selfefficacy and social environment.This research provides policy suggestions for the authorties to carry out effective risk communication,and social conflict prevention,which is conducive to promoting the harmonious development of society to realize the real "people-oriented" return of the engineering projects. |
