This paper presents a comparative analysis of the technology gap, energy efficiency, and CO2 emission performance of the agglomerated cities in Eastern and Central China and South Korea under economic heterogeneity. The potential reductions of energy and CO2 emission are estimated from agglomerated city perspectives. The global meta-frontier non-radial direction distance function is used to conduct an empirical analysis of agglomerated cities among Eastern, Central China and South Korea. The results show the potential reduction of 7.58 billion tons of CO2 emissions in Korea and another potential reduction of 1930.62 toe energy for the research period in China, if Korea and China proactively collaborate with each other. The empirical results conclude several unique findings and their implications. First, there are significant differences between the Chinese and Korean cities, in energy efficiency, CO2 emission performance, and meta-technology gaps. Korean cities play a leading role at benchmarking efficiency level with meta-frontier technology. Second, there is no significant difference between total-factor and single-factor performance indexes in the Korean cities, because South Korea requires large capital stocks to replace energy in the production process. However, the opposite is true for Eastern and Central China cities. Finally, there is huge potential for the Chinese cities to reduce energy and CO2 emissions by “catching up” internally as well as by the collaborative efforts with Korean cities.

LANGUAGE NOTE | Document text in English; abstract also in Chinese.The purpose of this study was to do a comparative analysis of the critical coaching interventions surrounding the use of timeouts employed by male university coaches. Little examination of such game related coaching decision making as a measure of coaching effectiveness has been conducted, particularly at the international level. Fifty-five male coaches of men’s university basketball teams from four different countries (Canada, Hong Kong, South Korea, Taiwan) were analyzed using a questionnaire consisting of demographic questions and a specific six-factor, 26-item timeout questionnaire. Analysis of variance with Scheffe post hoc multiple comparisons was used to examine the results. The findings were: 1. Canadian and South Korean coaches were older and more experienced than coaches from the other countries with Canadian coaches holding more formal certification qualifications. 2. Age, experience and qualifications, however, made no statistically significant difference to the overall results. 3. The "physical" factor was the most common reason for calling timeouts with Hong Kong coaches using this reason most often. 4. The "emotional" factor was the least used reason for calling timeouts for Canadian coaches but was used most often by Korean coaches. 5. Canadian coaches were less likely to use timeouts while Korean coaches were most likely. Canada and Taiwan scored consistently higher than Hong Kong and South Korean coaches and were more similar in their emphasis on all factors. The results suggest a clear difference in the approach to timeout decision making among the coaches from the four countries with the Canadian strategy being consistently different than the other countries of Hong Kong, Taiwan and especially South Korea. The highest emphasis on "physical" factor indicated the importance of using timeouts as a means of controlling team fatigue and energy expenditure.本研究之目的在於分析大學男子籃球敎練在使用暫停的關鍵抉擇。以往較少研究使用比賽中敎練的決定去分析敎練的敎授成效，本問卷以六種決策方式，分26項來分析四個國家(加拿大、香港、南韓及台灣)的大學男子籃球隊敎練的決策因素，並分析跨國的異同關係。研究指出：一. 加拿大及南韓的敎練年齡較長、經驗較深，而加拿大敎練具有較多正規的証書資格。二. 年齡、經驗及資格與決定因素並無明顯的相關。三. 香港敎練較常以體能因素去請求暫停。四. 加拿大敎練較少以心理因素去請求暫停，而反之南韓敎練則較多。五. 加拿大敎練較少請求暫停而南韓敎練則較多。而在整體因素方面，加拿大及台灣敎練的取向相似並較香港及南韓敎練為高。結果指出加拿大敎練在請求暫停的決定方面與其他國家有明顯的分別，以南韓為甚。體能因素備受重視則引出暫停用作控制球隊疲累及能量消耗問題的重要性。

Abstract Green innovation undoubtedly plays a significant role in creating employment opportunities, boosting green economic activity, and improving environmental sustainability. This study scrutinizes the effect of energy efficiency and green innovation on CO2 emissions in China over the 1992–2014 period using NARDL. Findings show that energy efficiency and green innovation contribute to reducing CO2 emissions in China. Energy efficiency and green innovation are also important asymmetric determinants of CO2 emissions. An increase in energy efficiency and green innovation lowers CO2 emissions, while a decrease in energy efficiency and green innovation increases CO2 emissions in China in the long run. Some policy measures are suggested to attain carbon neutrality.

Emissions Intensity

As the largest emitter in the world, China has pledged to reduce CO2 emissions intensity (CO2 emissions per unit of output) by 60–65% between 2005 and 2030. CO2 emissions intensity inequality analysis in China can provide a scientific basis for the Chinese government to formulate reasonable regional carbon emission abatement strategies, so as to realize the goal above. This paper adopted the Theil index to study the provincial-level CO2 emissions intensity inequality in China during 2005–2015. The regional decomposition was firstly conducted and then the factors of interregional and intraregional inequalities were explored. The results show: (i) a clear increase in provincial CO2 emissions intensity inequality in China has happened; (ii) this inequality and its increase were both mainly explained by the intraregional component; and (iii) the energy efficiency was the most important and positive contributor in the interregional, Eastern, Central, and Western China inequalities. Energy efficiency was also the key factor that caused the growth in interregional and Western China inequalities. However, most of the Eastern and Central China inequality increments over the whole period were respectively driven by the expanding carbonization gap and the changing GDP share, instead of the trajectory of energy efficiency. According to the results, regional emission mitigation strategies were proposed.

CO2 emissions from international shipping could increase between 50-250% by 2050 year. The EEDI (Energy Efficiency Design Index) is a key requirement for regulating CO2 emissions of maritime transport; a requirement was introduced in 2011 by the International Maritime Organization and came into force gradually. In recent studies it was investigated that no other technologies has the potential and reserves compared to Cogeneration systems. The article provides a short review of ship energy efficiency design index improving technologies and cogeneration systems application for maritime transport. A brief comparative analysis of cogeneration cycles is provided also. CO2 emissions from international shipping could increase between 50–250% by 2050 year.

Based on the strong similarities between energy-resource-poor and fossil-fuel-centered economies (e.g., Taiwan, Japan, and South Korea) in terms of economy, culture, and energy usage characteristics, they should be analyzed collectively. This study adopted two-tier input-output structural decomposition analysis to identify the driving forces behind CO2 emissions to these countries to the formulation of effective environmental policy. Data from the World Input-Output Database was used to decompose relative changes in CO2 emissions into a range of technological advances, factor substitution, and final demand effects. Technological advances in energy (direct) contributed to a 77% reduction in Taiwan and a 34% reduction in South Korea. This is a clear indication that improving energy efficiency via technological advances should be a priority. In Japan in particular, there was a 22% reduction in CO2 emissions attributable to technological advances in materials; hence, it is recommended that Taiwan and South Korea work to extensively develop eco-industrial parks to create industry clusters to promote resource/energy efficiency and reductions in CO2 emissions. Decomposition results based on factor substitution revealed that a variety of strategies will be required, such as switching to fuels that are less carbon intensive, promoting the adoption of renewable energies, and implementing clean-coal technologies.
