This paper explores the potential of heterogeneous Granger analysis in transport geography research by applying this method to a specific case of the often complex and potentially reciprocal linkages between the deployment of transport infrastructures and spatial economic development: the linkages between rising intra-regional volumes of trade and air passenger traffic in Asia-Pacific. Although conceptual and empirical linkages between both indicators can be assumed based on previous research, relatively little is known about the actual causality. Using heterogeneous Time Series Cross Section Granger causality analysis for the period 19802010, we explore the presence of four causality scenarios amongst different country-pairs: (1) there is no co-evolution, implying that both patterns develop independently (e.g. JapanAustralia); (2) there is real co-evolution in that both patterns influence each other through feedback loops (e.g. South KoreaPhilippines); (3) air passenger traffic is facilitated by trade (e.g., South KoreaPhilippines); or (4) trade is facilitated by air passenger traffic (e.g. AustraliaMalaysia). Some tentative interpretations of this heterogeneity are offered.
