Constraints to achieve infrastructure sustainability for mountainous townships in China

This paper investigates the constraints to achieving optimal infrastructure sustainability for mountainous townships in Southwest China. Although such townships are relatively less developed, it is well recognized that investment in infrastructure projects in less developed townships plays a vital role in China's sustainable development mission. While the benefits of infrastructure investments are usually measured by means of economic performance, their long-term sustainability performance is largely overlooked. It is therefore imperative to understand the constraints that impede infrastructure sustainability and what corrective actions can be taken. The constraints are identified in this study via exploratory factor analysis and structural equation modeling. Twenty-one townships in the mountainous regions of Southwest China were investigated by means of a questionnaire survey. The study reveals that the major constraints include four dimensions: “Economic Capacity”, “Governance and Management”, “Policy Instrument and Public Participation”, and “Local Geographic Characteristics”. Identification of these constraints provides a valuable reference for local governments to take adequate measures to ensure that their infrastructure sustainability can be improved.
