“…Also, the PPML estimator less affected by heteroscedasticity and heterogeneity as it deals adequately well with large amounts of cross-sectional data in bilateral trade ows. In addition, in terms of the best estimator for consistent estimates of gravity model coe cients, the PPML has proved to be robust and also consistent with small as well as large sample size according to the literature (see for example, Bobkova 2012;Chang et al, 2021;Vavrek 2018). 2 Readers should refer to the United Nations Conference Database Statistics on the variables that are used to computes the LSCI and LSBCI variables.…”

Maritime transport significantly affects virtually all aspects of international trade globally. Following this, it becomes imperative to understand the positive influence of maritime transport in the improvement of intra-African trade performance. This paper, therefore, investigates the extent to which maritime transport boosts intra-African trade performance within the framework of the gravity model in a sample of 32 African countries for the period 2010–2018. The paper reveals that maritime transports enhance intra-African trade performance; greater access to maritime transports is associated with an increase in intra-African trade performance. Based on this outcome, it is recommended that policies that increases maritime transports are what policy makers should prioritize and pursue. JEL Codes: C33; F10; I30; O55.

“…In the selection of input-output elements for port efficiency evaluation, most studies select input elements from port infrastructure or equipment approximating the capital level (Bonilla et al, 2004;Birgun and Akten, 2005;Wiegmans and Witte, 2017;Chang et al, 2021), such as berth length or depth, number or intensity of cranes; output elements mostly select container throughput or cargo throughput (Cullinane and Wang, 2006;Chang et al, 2021), only a tiny number of scholars regard passengers as an output factor (Simões and Marques, 2010;Tovar and Wall, 2019); at the same time, some scholars also examine non-desired output factors, such as carbon dioxide emissions (Na et al, 2017;Dong et al, 2019).…”

In 2020, China proposed the country’s dual carbon goals of peaking carbon emissions by 2030 and achieving carbon neutrality by 2060. Under the dual carbon goals, the low-carbon transformation has become an important development direction for Chinese ports. Taking eight ports in China’s Bohai-rim port group as an example, this study adopts the Slacks-Based Measure (SBM) model to evaluate the port efficiency considering the environmental factor of carbon dioxide (CO2) emissions. The results show that the average scale environmental efficiency of the eight ports during 2005-2020 is the highest, followed by local pure technical environmental efficiency and global technical environmental efficiency. The efficiency values of each port under different environmental efficiency categories vary greatly. Overall, each port is in a state of environmental inefficiency. From port technology, input-output optimization, supervision, and management of relevant departments, recommendations for improving the environmental efficiency of ports under the dual carbon goals are put forward.

“…However, there are three drawbacks that make it difficult to use for the resource reallocation among air routes. Firstly, the traditional model should minimize or maximize all inputs or outputs variables at the equal ratio due to the radial assumption (Chang et al, 2021). More specifically, the classical input-oriented radial DEA uses the proportional reduction of input vectors approach, which ignores slacks while projecting each DMU to the frontier line (Tone, 2001).…”

PurposeSince airlines that employ their resources effectively will achieve operating profitability, air route resource allocation is significant for airlines. This study aims to investigate an appropriate model to reallocate resources into each air route of an airline company.Design/methodology/approachThis study proposes a network centralized data envelopment analysis (DEA) models with slack-based measure (SBM). The proposed model not only takes into account the two interconnected stages but also considers the nonradial approach with transfer-in and transfer-out slacks for resource reallocating. Furthermore, the authors modify the objective function to an input-oriented function with SBM, and divide the model into passenger and freight parts, which makes the model more realistic for the characteristic of air routes.FindingsThe empirical analysis using an airline company's internal data provides airline operators with information on how they increase or decrease input resources, which can serve as a practical guideline of resource reallocation. Specifically, the results indicate that the airline company should increase their input resources into long-haul air routes such as KOR-OCN while decreasing their input resources into short-haul air routes such as Korean-Oceania (KOR-OCN), Korean-Chinese (KOR-CHN), Korean-Southeast Asian (KOR-SEA), Korean-Japanese (KOR-JPN).Originality/valueAlthough some papers evaluate air route efficiencies based on the DEA approach, a few existing papers have addressed resource allocation for air routes. This paper is the first to study the resource reallocation for air routes based on the DEA approach, contributing to the literature in expanding the scope of research on resource reallocation.
