Research paper thumbnail of Transport-mode competition in intra-national trade: An empirical investigation for the Spanish case

Transportation Research Part A: Policy and Practice, 2017

Trade within and between countries can take place by alternative transport modes. Economic and lo... more Trade within and between countries can take place by alternative transport modes. Economic and logistical complexity is fostering multimodality as well as transport-mode competition. The international trade literature has given little attention to this issue. The aim of this paper is to analyze transport-mode competition in inter-provincial deliveries within Spain. To this end, we use a novel dataset with fifty inter-provincial, industry-specific flows by four transport modes (road, train, ship and aircraft). We then feed this dataset into various specifications of a gravity model that incorporates cross-sectional dependence attributable to unobservable factors directly associated with implicit and explicit transport-mode competition schemes. In considering alternative distance segments, we also test for competition effects between road and the other three modes.

Consequently, it is standard to identify the origin of a flow with the point of production and the destination with the point of consumption. However, economic and logistical complexity may lead to a number of misrepresentations in the observation of specific dyadic records. Transport mode competition and cooperation, and the “hub-spoke” structures generated by them, may introduce bias in several types of analysis. From the econometric viewpoint, they can be considered an additional source for cross-sectional correlation between dyadic flows. The aim of this paper is twofold: first, to analyze transport-mode competition in inter-provincial deliveries in Spain and, second, to analyze some of these potential biases. To this end, we use a novel dataset with fifty inter-provincial, sector-specific flows occurring via four alternative transport modes. We then feed this dataset into various specifications of a gravity model that incorporates cross-sectional dependence attributable to spatial autocorrelation and hub-spoke structures.

However, the presence of hub-spoke structures or multimodal flows may introduce bias, such as being an additional source for cross-sectional correlation between dyadic flows. The aim of this paper is to model inter-provincial flows within a country (Spain) considering this potential bias using a novel dataset with fifty inter-provincial flows and four transport modes. We then feed this dataset into various specifications of a gravity model that incorporates cross-sectional dependence attributable to hub-spoke structures.

The results obtained show the existence of an important border effect in favour of the intraregional trade of tourism, and verify a minor elasticity of the trade flows in some characteristic tourism sectors in relation to distance. Finally, the two main typologies of flows – tourist establishments and second homes – are modelled separately, identifying specific factors for explaining each category.

In relation to social networks, it has been shown that the intensity of trade of goods is positively correlated with the migration flows between any pair of countries/regions. In this article it is investigated if such a relation also holds for the Spanish domestic trade flows of services. With this aim, a gravity model rooted in the Dixit–Stiglitz–Krugman theoretical frameworks is used taking advantage of a unique dataset on interregional trade flows of some of the main sectors linked to Tourism, namely, Accommodation and Restaurants. A different analysis of each sector separately is carried out, finding a big positive effect for Restaurants, but no effect for the Hostel industry. These novel results can be explained by forces driving the demand in each sector. Migration linkages are measured by means of Register data, regarding the stock of people born in each region living in the others. Business networks are approached by a matrix of companies in different regions operating in these key sectors that are connected.
