Better transport infrastructure and regional economic integration are correlated. However, the causal relationships between these concepts and the extent of their mutual impacts are still ambiguous. This study selects the Chang-Zhu-Tan region (CZXR), one of the most important manufacturing areas in the Yangtze River economic belt, as study area. Based on relevant statistical data from 1990 to 2013, it analyses the regional economic integration level (REIL) of the CZXR using regional economic linkage and urban flow intensity models, and the transport infrastructure construction level by dividing it into transport investment level (TIL) and transport mobility level (TML). Before 2005, the REIL was relatively low with a rather slow growth rate, but the situation has significantly improved since 2005. And the growths of TIL and TML are not synchronized in the time series; however, the range and duration of the gap between TIL and TML are constantly shrinking. Finally, the relationships among REIL, TIL, and TML are examined by using a vector auto-regression model and Granger causality test. The results indicate unidirectional Granger causality among REIL, TIL, and TML, which means TIL and TML can promote REIL. However, the impacts of TIL and TML on REIL are not fully synchronized in the time series, and TIL contributes more to REIL than TML does. According to our findings, policymakers should view transport mobility as a vital public good and improve it to promote regional economic integration.
