Investigating the Sustainability Performance of PPP-Type Infrastructure Projects: A Case of China

Abstract

In China, the demand for public infrastructure projects is high due to the acceleration of urbanization and the rapid growth of the economy in recent years. Infrastructures are mainly large scale, so local governments have difficulty in independently completing financing work. In this context, public sectors often seek cooperation from private sectors, in which public-private partnership (PPP) is increasingly common. Although numerous studies have concentrated on sustainable development, the unsustainability performances of infrastructures are often reported on various media. Furthermore, studies on the sustainability performances of PPP-type infrastructure (PTI) projects are few from the perspective of private sectors' behaviors. In this study, we adopted the modified theory of planned behavior and the structure equation model and conducted a questionnaire survey with 258 respondents for analyzing the sustainable behaviors of private sectors. Results indicated that behavioral attitude, perceived behavioral control, and subjective norm interact significantly. They have direct positive effects on behavioral intention and then indirectly influence actual behavior through this intention. Actual sustainable behaviors of private sectors have significantly positive effects on the sustainable development of cities. We offer theoretical and managerial implications for public and private sectors on the basis of the findings to ensure and promote the sustainability performances of PTI projects.

Understanding the Intention and Behavior of Renting Houses among the Young Generation: Evidence from Jinan, China

“…This is similar to the findings in previous studies that perceived that green values have a significant impact on the loyalty of public bicycle systems through sustainable modified TAM and TPB [73]. Moreover, the conclusion is consistent with that of Justin Paul, which indicates that the attitude towards the behavior (ATT) considerably influences the prediction of green product consumption [88,89]. Therefore, perceived usefulness and perceived usability are relevant factors in green consumer behavior.…”

“…Behavioral intention also affects actual behavior (0.31), indicating that when the willingness to rent is strong, young consumers will rent, which is related to the personal qualities of the younger generation in China. This conclusion is not entirely consistent with the finding of Zheng partly due to the different resources of the respondents [89].…”

Evaluating the Intention and Behaviour of Private Sector Participation in Healthcare Service Delivery via Public-Private Partnership: Evidence from China

“…Malaysian scholars applied a modified TPB model, which explained the effect of the private sector's intention and attitude to participate in socially responsible investments [72]. In addition, TPB could be considered a framework to evaluate the willingness of private capital to invest in normal PPP projects and analyse the connection between the private sector and PPP performance [73,74]. In CHM, researchers applied TPB to examine the patients' willingness to seek treatment [75], consuming intention on medical products and nurturing personal health behaviour [76,77].…”

Infrastructure Operation Efficiency and Influential Factors in Developing Countries: Evidence from China

“…Qin et al argued that the major question of China's infrastructure industry has changed from insufficient supply to improved supply quality and efficiency [7]. Zheng et al were also concerned with the sustainability performance of infrastructure [8].…”
