This research investigates the co-movement and causality relationships between greenhouse gas emissions, energy consumption and economic growth for 16 Asian countries over the period 1990–2012. The empirical findings suggest that in the long run, bidirectional Granger causality between energy consumption, GDP and greenhouse gas emissions and between GDP, greenhouse gas emissions and energy consumption is established. A non-linear, quadratic relationship is revealed between greenhouse gas emissions, energy consumption and economic growth, consistent with the environmental Kuznets curve for these 16 Asian countries and a subsample of the Asian new industrial economy. Short-run relationships are regionally specific across the Asian continent. From the viewpoint of energy policy in Asia, various governments support low-carbon or renewable energy use and are reducing fossil fuel combustion to sustain economic growth, but in some countries, evidence suggests that energy conservation might only be marginal.

The spallation target is the component coupling the accelerator and the reactor and is regarded as the "heart" of the accelerator driven system (ADS). Heavy liquid metal lead-bismuth eutectic (LBE) is served as core coolant and spallation material to carry away heat deposition of spallation reaction and produce high flux neutron. So it is very important to study the heat transfer process in the target. In this paper, the steady-state flow pattern has been numerically obtained and taken as the input for the nuclear physics calculation, and then the distribution of the extreme large power density of the heat load is imported back to the computational fluid dynamics as the source term in the energy equation. Through the coupling, the transient and steady-state temperature distribution in the windowless spallation target is obtained and analyzed based on the flow process and heat transfer. Comparison of the temperature distribution with the different beam intensity shows that its shape is the same as broken wing of the butterfly. Nevertheless, the maximum temperature as well as the temperature gradient is different. The results play an important role and can be applied to the further design and optimization of the ADS windowless spallation target.

PurposeThe purpose of this study is twofold. First, this research estimates banks' efficiencies from the perspectives of resource utilization and investment after incorporating risk measures as an exogenous input in the investment-efficiency stage. Second, the current study examines the relationship between intellectual capital (IC) and banks' efficiencies.Design/methodology/approachFirst, this study uses a dynamic network data envelopment analysis approach in investigating the efficiencies of 24 Taiwanese banks in 2007–2018 from two perspectives. Second, this research utilizes various regression techniques, namely, ordinary least squares (OLS), robust least squares and truncated regression, to gauge the impact of IC on banks' efficiencies. Typically, IC is determined based on a monetary value-based measure and value-added intellectual coefficient (VAICTM).FindingsResource-utilization (investment) efficiencies were observed as 0.941 (0.964), thereby contributing to the mean overall efficiency of the sample banks at 0.952. However, the related efficiency changes decline over the sample period, thereby suggesting that the average banks' efficiencies hardly increase. Regression analyses show a significantly positive relationship between IC and banks' overall resource-utilization and investment efficiencies.Research limitations/implicationsOverall, this study suggests that researchers should consider risks when estimating banks' efficiencies owing to their connection to banks' investment performance. From banks' dynamic two-stage efficiencies, this study demonstrated that investments in IC will bring improved future economic benefits.Originality/valueDifferent from prior studies, this study improves banks' efficiency evaluation models by incorporating risk measures and assuming weighted periods for the 2007–2008 global financial crisis. Moreover, the use of monetary value-based measure of IC provides consistent results as the commonly-used VAICTM does.

AbstractThis study examines how the (i) overall environmental, social, and governance (OESG) performance; (ii) three individual E, S, and G (IESG) performance; and (iii) subcomponents of the three individual E, S, and G (SIESG) performance affect 29 Apple Incorporation partners' energy‐adjusted firm efficiency from a nonlinear perspective. Our truncated regression findings from 145 firm‐year observations for the period of 2016–2020 indicate that the association between OESG performance and energy‐adjusted firm efficiency is U‐shaped. However, this nonlinear U‐shape exists in the individual S and G but not E of the IESG performance. Moreover, only certain subcomponents of the SIESG performance are nonlinearly related to energy‐adjusted firm efficiency. Overall, we highlight both the costs and benefits of the ESG performance for maintaining sustainable development and stakeholder engagement. The energy‐adjusted firm efficiency estimated through the multidimensional data envelopment analysis approach is also noteworthy for policy and decision‐making purposes.

AbstractThe cultural and creative industries (CCIs) in Taiwan have gradually contributed to the national economy under the impetus of government policies. We employ a two‐stage data envelopment analysis model with an additive efficiency decomposition approach to measure the profitability and marketability of 22 Taiwanese cultural and creative companies. Furthermore, we employ the network‐based ranking approach to identify benchmark inputs/outputs, and the strengths and weakness of each company. Our empirical results show that the profitability of the cultural and creative companies is better than their marketability. Companies in the industries of publishing, creative life, popular music, and cultural content averagely perform better than those in the other three types of CCIs in terms of profitability. Companies in the creative life industry are on average more efficient than those in the other five types of CCIs in terms of marketability. The profitability/marketability matrix of cultural and creative companies is also presented.

This paper examines the relationship between corporate social responsibility (CSR) and corporate performance. Using a two‐stage approach, we first evaluate the efficiency and metafrontier framework of companies in the US telecommunications industry. In the second stage, we run ordinary least squares regression analysis to examine the relationship between CSR and corporate performance. Our first‐stage findings show that the sample companies should first improve their scale inefficiencies rather than the inefficiencies in management practices. Through analysis on metatechnology ratios, we provide an insight on the potential improvement in performance caused by changes in the production environment. Our second‐stage analysis shows that the social aspects of CSR have positive impacts on corporate performance. Overall, this study contributes to increased understanding of the social aspects of CSR and the performance of US telecommunications companies. Copyright © 2014 John Wiley & Sons, Ltd.
