Research on Transportation Infrastructure Investment based on Economic Sustainable Development

Abstract

The article explored the influence of transportation infrastructure investment on economic sustainable development with time series data of 1981-2017. Additionally, the cointegration theory and Grainger causality test were applied to analyse the relationship between transportation infrastructure investment and economic sustainable growth based on the C-D production function model. The results show that the investment in transportation infrastructure still has a stable effect on promoting long-term and short-term economic development.
