The implementation of prefabricated housing (PH) has become prevalent in China recently due to its advantages in enhancing production and energy-saving efficiency within the construction system. However, stakeholders may not always fully realize the benefits of adopting PH due to the emergence of transaction costs (TCs) in the development process of such projects. This study investigated the strategies for developers to make rational choices for minimizing the TCs of the PH project considering their own attributes and external constraints. A Bayesian Belief Network model was applied as the analytical method, based on surveys conducted in China. A single sensitivity analysis indicated that developers influence the TCs of PH through the following three most impactful factors: prefabrication rate, PH experience, and contract payment method. Integrated strategies are recommended for developers in various situations based on a multiple sensitivity analysis. Developers facing challenges due to high prefabrication rates are advised to reduce the risks by procuring highly qualified general contractors and adopting unit-price contracts. For developers with limited PH experience, adopting the Engineering–Procurement–Construction procurement method is the most efficient way to reduce their TCs in the context of China’s PH market. This study contributes to the current body of knowledge concerning the effect of traders’ attributes and choices on TCs, expanding the application of TC theory and fulfilling the study on the determinants of TCs in construction management.@en

Introduction: Resident participation has gained increasing prominence and significance in the pursuit of sustainable neighborhoods regeneration. However, the current state of resident participation practices remains beset by several challenges, which present formidable impediments to the initiation and execution of neighborhood regeneration initiatives. This study aims to investigate the underlying mechanisms of residents’ participation behavior to enhance resident participation in neighborhood regeneration projects. Methods: The present study employs the extended Information-Motivation-Behavioral (IMB) model to examine the determinants and mechanisms influencing residents’ willingness and participation in neighborhood regeneration projects, with a specific focus on the Chinese context. Drawing upon data from 477 meticulously validated questionnaires administered to residents, the study applies structural equation modeling (SEM) to unravel the intrinsic dynamics of residents’ participation behavior. Results: The empirical findings of this research reveal that information, motivation, and the perceived local government support all exert a significant impact on residents’ participation willingness. Notably, motivation emerges as the most influential factor. Discussion: This study uncovers a direct influence of local government organizations on both residents’ willingness and their actual participation, suggesting that government organizations can spearhead innovative strategies to bolster residents’ willingness and furnish avenues for translating willingness into tangible participation. The outcomes of this study furnish an indispensable theoretical framework and offer policy recommendations that hold paramount importance for the deployment of novel interventions geared toward stimulating active involvement of residents in neighborhood regeneration.@en

Neighborhood regeneration has become essential component of environmental improvement, and promoting resident participation is a key aspect of effective environmental management. However, in China, the legacy of the former housing allocation system and specific cultural contexts have led to residents' psychological inertia towards participating in neighborhood regeneration. Although there has been extensive research on encouraging resident participation, most studies fail to recognize that cultivating active participation behavior among residents usually requires overcoming their existing reluctance or psychological inertia first. Grounded on the innovative notion of psychological inertia, this paper puts forth the perspective that to foster resident participation, it is imperative to initially disrupt their current participation inertia and subsequently facilitate the reconfiguration of their participation behavior. Specifically, it addresses two key research questions: (i) which factors are conducive to stimulating residents to overcome inherent psychological inertia and stimulate their positive participation attitudes? (ii) How do these stimuli shape and reconstruct residents' participation behavior? Based on the Stimulus-Organism-Response (SOR) theory and structural equation modeling (SEM), this paper unveils the mask of intrinsic mechanism for overcoming psychological inertia and reshaping residents' participation behavior. The empirical results show that three stimulating factors (information acquisition, social norms, and perceived grassroots government support) directly impact residents' participating attitudes; these stimuli reconstruct participation behavior by triggering individual psychological changes and then inducing behavioral changes. With the new insight of “overcoming psychological inertia” and the incorporation of behavioral psychology in restructuring resident participation behavior, this paper presents implementation strategies for promoting resident participation in neighborhood regeneration.
