Abstract
Mega infrastructure projects provide a basic guarantee for social development, economic construction, and livelihood improvement. Their operation and maintenance (O&M) management are of great significance for the smooth operation and the realization of the value created by the projects. In order to provide an approach for effectively evaluating O&M management, this study develops a holistic indicator system using a mixed-review method from the national macro perspective in China. In this study, literature analysis, policy texts, expert interviews, and grounded theory were used to collect relevant data at home and abroad, and establish an initial evaluation indicator system with 23 indicators covering two dimensions and five aspects. Then the questionnaire survey and factor analysis were used to score and categorize the indicators, and finally an evaluation indicator system for O&M management of mega infrastructure projects was formed. The results show that social relations, environmental benefits, macro policy, and operational capacities play an important role in the evaluation of the O&M of mega infrastructure projects. This study helps the management team to avoid negative impacts in the O&M management of mega infrastructure projects and lays a theoretical foundation for future research. The indicator system in this study is based on the Chinese context, and it remains to be verified whether the indicator system is applicable to other countries due to the differences in political and cultural backgrounds in different regions.
Highlights
At present, megaprojects all over the world have entered the “trillions era” [1]
The operation and maintenance (O&M) indicator system studied in this paper is essentially a complete system set up to achieve the ultimate goal of the operating entity of mega infrastructure projects—that is, the level of O&M is identified by judging the extent to which mega infrastructure projects achieve their operational goals
According to the indicator contribution rate ranking, it can be seen that social relations play a crucial role in the O&M management of mega infrastructure projects
Summary
Megaprojects all over the world have entered the “trillions era” [1]. During the past few decades, China has carried out the largest infrastructure activities in history, which has become a powerful driving force to promote China’s urbanization construction, economic development, and improvement of people’s living standards [2]. By the end of 2019, the country’s infrastructure investment exceeded CNY 18.5 trillion, the total operating mileage of high-speed railways exceeded. 35,000 km, accounting for more than two thirds of the total mileage of high-speed rail in the world, and the mileage of expressways exceeded 140,000 km, ranking first all over the world [3]. Mega infrastructure projects, as large-scale social activities, involve a wide range of. Public Health 2020, 17, 9589; doi:10.3390/ijerph17249589 www.mdpi.com/journal/ijerph
