Study on the effectiveness of using transport routes and transport vehicles through analysing the effects of them on transportation output: The case of China

Abstract

This study investigates the impact of 16 exogenous variables, such as transport routes and vehicles, on two endogenous variables: the growth of transported passengers' output and the growth of carried goods' output in China. The research also delves into how endogenous variables affect the average distance traveled by passengers and goods. The methodology encompasses structural equation modeling (SEM) analysis with goodness of it tests conducted in three steps using Stata 17.0 software. A cargo medium vehicle positively influences the growth of goods shipped and passengers transported, while negatively affecting the average passenger distance traveled. A Heavy Cargo Private Vehicle has a negative impact on the growth of passengers transported. Electrified Railway Length positively influences the growth of passengers transported. Growth of passengers transported positively affects the growth of goods shipped. Positive effects of exogenous variables on endogenous variables result in positive effects on other variables, suggesting an increase in exogenous variables. Negative effects of exogenous variables on endogenous variables lead to positive effects on other variables, suggesting a decrease in exogenous variables. Positive effects of exogenous variables on endogenous variables do not influence other variables, recommending an increase in exogenous variables.
