ICT Adoption among Logistics Companies in ASEAN Countries

In this era of globalization, adoption of information and communication technology (ICT) is one of the critical determinants of logistics companies' competitiveness and growth. This is especially so for the ASEAN countries as they pursue the vision of regional economic development and integration. Existing empirical studies on ICT adoption by logistics companies in developing countries are, however, scarce and have limited theoretical support and so far no comparative analysis of ICT adoption among ASEAN logistics companies and its determinants has been undertaken. This paper investigates the level of ICT adoption among ASEAN logistics companies and also develops an investment-based model to explain it. The model is evaluated with logistic regression using firm-level data collected from interviews with a sample of ASEAN logistics companies. The study finds that ICT adoption level varies significantly among the ASEAN countries and provides an empirical support for an investment-based view of ICT adoption. It also finds no further evidence for the relevance of the institutional theory to the ASEAN logistics industry. These findings have important strategic and policy implications for the ASEAN policy-makers and logistics industry.

西方航运资本的入侵与上海的近代海运业

鸦片战争之后西方资本入侵中国，洋轮直驶我国沿海江河，传统的木帆船运输业受到剧烈冲击，急速衰落，但以轮船为标志的近代海运业出现了。上海的近代海运业由外国资本、本国官僚资本和民族资本等３种成份构成。西方资本的航运企业垄断上海的航运业达１００年，掠取了中国人民的巨额财富。官僚资本的轮船招商局在西方资本航运企业的刺激影响下出现，又在其排挤、打击下艰难地生存和发展。民族资本的轮船公司深受西方资本和官僚资本的双重抑制、打击，生存更为艰难，历程异常坎坷。     

Meta-frontier function approach to operational efficiency for shipping companies

ABSTRACT

This study uses a meta-frontier function approach to estimate operational efficiency and technology gaps for shipping companies. Researchers have evaluated the relative efficiency of shipping firms with the assumption that shipping firms operate under one frontier technology. However, the assumption of one frontier technology is being argued by efficiency literature. Therefore, this study estimates relative efficiency of shipping firms in different market segments (dry bulk, liquid bulk, and containerized cargo), possibly operating with different technologies and, hence, under different frontiers. This study uses a meta-frontier function approach that allows us to distinguish separate frontiers for different groups and decompose efficiency scores relative to the meta-frontier. Data used in this study is collected from Thomson One Banker from 2001-2013 in the form of unbalanced panel data. Empirical results suggest that dry bulk firms’ production technology is more advanced than others and the production frontier is the closest to that of the meta-frontier. In addition, efficiency scores are all low, but containerized cargo firms achieve higher technological efficiency than the other two groups. It is also suggested that containerized cargo and liquid bulk firms should prioritize improvements in their production technology and dry bulk firms should prioritize improving group efficiency.

Exploring the influence of built environment on Uber demand

Ride-sourcing services have made significant changes to the transportation system, essentially creating a new mode of transport, arguably with its own relative utility compared to the other standard modes. As ride-sourcing services have become more popular each year and their markets have grown, so have the publications related to the emergence of these services. One question that has not been addressed yet is how the built environment, the so-called D variables (i.e., density, diversity, design, distance to transit, and destination accessibility), affect demand for ride-sourcing services. By having unique access to Uber trip data in 24 diverse U.S. regions, we provide a robust data-driven understanding of how ride-sourcing demand is affected by the built environment, after controlling for socioeconomic factors. Our results show that Uber demand is positively correlated with total population and employment, activity density, land use mix or entropy, and transit stop density of a census block group. In contrast, Uber demand is negatively correlated with intersection density and destination accessibility (both by auto and transit) variables. This result might be attributed to the relative advantages of other modes – driving, taking transit, walking, or biking – in areas with denser street networks and better regional job access. The findings of this paper have important implications for policy, planning, and travel demand modeling, where decision-makers seek solutions to shape the built environment in order to reduce automobile dependence and promote walking, biking, and transit use.     

Evaluating efficiency in the Norwegian bus industry using data envelopment analysis

This paper focuses on the performance of Norwegian bus companies subsidized by the government. The performance is evaluated from a productive efficiency point of view. The framework is that of a deterministic non-parametric Data Envelopment Analysis (DEA) approach to efficiency measurement. In this context several important issues are addressed: efficiency rankings, distribution and scale properties in the bus industry, potentials for efficiency improvements in the sector, the impact of ownership, area of operation and scope, and ways of improving efficiency in the sector. The findings show that the average bus company exhibits increasing return to scale in production of its services. The extent of such returns however vary, with size and is more prevalent among smaller companies. The average bus company is found to have a considerable input saving potential of about 28 percent. Neither economies of scope nor company ownership are found to have an influence on company performance. It is suggested that geographical factors need a closer attention in future research. The implications of DEA results are discussed and concluding remarks offered.
