Effects of port-shipping logistics integration on technical and allocative efficiency

It is well known that the international logistics and supply chains are subject to the domination of seaports and shipping lines each with increasingly significant market power. This implies that international supply chains, which typically involves sea transport as a key chain segment, could be subject to the double marginalisation problem. This means, chain operators are likely subject to both technical and allocative efficiency issues. The former is related to the use of inputs in production and distribution, and the latter is generally related to the market structure that affects resource allocation. The current study seeks to study the simultaneous relationships between three components, namely logistics integration, technical efficiency, and allocative efficiency in international container shipping. Exploratory factor analysis and structural equation modelling are conducted using data collected from a survey of global shipping lines. The analysis results show that logistics integration comprises of two main interrelated aspects, namely relational integration, and operational integration. It has significant effects on both technical and allocative efficiency. Technical efficiency and market contestability are affected by relational integration, while allocative efficiency and infrastructure capacity are affected by operational integration. Based on the analysis results, implications for port, terminals and stakeholders are also discussed.
