环境规制对碳效率的多重路径及门槛模型研究

从结构升级及效率提升两大维度刻画环境规制对碳排放效率的关系及作用机制,研究环境规制是如何提升城市碳排放效率的。基于2006—2019年中国279个城市层面数据,采用非参数百分位自抽法,逐步回归法、Sobel检验和交互调节模型验证影响路径,并利用门槛模型探讨不同路径下环境规制的调节作用。结果表明：(1)环境规制促进城市碳排放效率提升,但存在区域异质性;(2)环境规制通过促进产业结构高度化、绿色技术创新和能源效率升级提高碳排放效率,产业结构合理化及产业集聚“遮掩”了环境规制的激励作用;(3)环境规制对提升碳排放效率存在多种门槛效应和调节机制。发挥环境规制对碳排放效率结构和效率的双重激励时,需注意不同路径的维度问题,以提高准度,把握力度。     

Does history repeat itself? Economic development and policy convergence in Vietnam and South Korea

With one of the world's fastest rates of economic growth since the 1990s, Vietnam could be seen as Asia's next tiger economy. This study examines whether there has been policy convergence between the older East Asian developmental state model of economic development and that adopted by Vietnam. The economic development trajectories of South Korea and Vietnam are compared to identify similarities and differences. It was found that while policy convergence is evident there is also some divergence between the two countries.     

The effect of core menu attribute,green menu background,and gender on consumers’ attitudes toward korean dishes

Given the healthy eating trends and the growing popularity of Asian cuisines in the USA, this research investigates the interaction effect of gender and two types of health cues, namely core menu attribute (perceived healthiness-chicken vs. beef) and menu background color (green vs. white) on consumer attitudes toward Korean dishes. Our findings indicate that pairing a chicken dish with a green menu background leads to highly favorable attitudes among females. Males, on the other hand, exhibit similar attitudes toward chicken and beef dishes with a green background. Such gender differences are attenuated with a white (neutral) menu background.     

Profit and equity trade‐offs in the management of small pelagic fisheries: the case of the Japanese sardine fishery*

The management of small pelagic fisheries is difficult due to environmental regime changes that generate multi‐decadal cyclic fluctuations in stock abundance. Lagged management responses to environmental factors can amplify the effects of fishing and may even result in stock collapse. In this paper, we develop an age‐structured bioeconomic model to explore the effectiveness of alternative management approaches for cyclically fluctuating small pelagic fish stocks. The fishery outcomes are evaluated against the overall profit of the fishery and the intertemporal distribution of fishing profits. The model is parameterised for the Japanese sardine fishery, once the largest fishery in Japan, which has experienced a prolonged period of stock collapse over the last 100 years. The results show that the duration of fishery collapse is mostly determined by the extent of cyclic fluctuations in the recruitment of immature sardines, but the effects of the fluctuations on the fishery are heightened by the cumulative impact of fishing. We further show that restricting fishing reduces the fishery’s overall profits, but smooths the intertemporal distribution of profits, resulting in greater intergenerational equity. This income smoothing effect is particularly pronounced when the stock exhibits high levels of cyclic fluctuations.     

Generation Y consumers’ selection attributes and behavioral intentions concerning green restaurants

The objectives of this study are to examine the Generation Y consumer segments’ selection attributes and behavioral intentions toward green restaurants. A survey was administered to college students between the ages of 17 and 30 at a university in a Southeastern United States city. This study identified four different consumer segments of Generation Y college students according to their food-related lifestyles. Across the four segments, there were significant differences in selection attributes. In addition, significant differences were identified between the four segments regarding their behavioral intentions toward green restaurants. Finally, the marketing implications for the target groups are discussed.     

Mergers and acquisitions and firm growth: Investigating restaurant firms

Merger and acquisition (M&A) has been viewed as an efficient strategy for firm growth because M&As allow firms to quickly achieve their ideal size. However, whether consistent growth can be maintained after an M&A is questionable because post-M&A integration is a difficult process. In order to identify whether M&A is really an effective tool for producing consistent growth in restaurant firms, this study examined post-M&A firm growth in comparison to non-M&A firm growth. Using financial data from 1980 to 2007, this study analyzed the sales growth of restaurant firms up to five years after an M&A. This study found that post-M&A growth patterns varied across firm sizes and time periods (from one to five years after an M&A). This study also revealed that both small and large acquirers experienced positive sales growth in the year following M&A. However, this positive effect completely disappeared during or after the third year post-M&A. M&A firms showed the same growth patterns as non-M&A firms three to five years after an M&A. This study provides useful post-M&A growth information regarding restaurant firms, which can be practically useful for firms considering M&A.     

Effects of compensation for service recovery: From the equity theory perspective

Using equity theory, this study investigated the importance of consumers’ entire history of shared interactions with service organizations, in addition to fairness perceptions, when evaluating recovery efforts following service failure. Specifically, this study empirically tested the different consequences of compensation by manipulating the consumer relationship level. The relationship level determines the perspective of equity (transactional equity perception versus cumulative equity perception) and motivates consumers to follow different psychological processes to redress service failure. An online survey using hypothetical scenarios manipulating recovery efforts and relationship level conditions was conducted to collect data. Mediation tests showed that perceived equity fully mediates the effect of compensation on a consumer's future behavioral intentions. The results of analysis of variance (ANOVA) showed that when additional compensation is offered after a service failure, perceived equity was found to increase regardless of the consumer's relationship level. However, enhanced equity perception does not automatically mean that corresponding future behavioral intentions are also enhanced. When consumers have a high customer–organization relationship, there is no difference in behavioral intentions between those who are compensated and those who are not. Managerial implications for restaurant operations are also discussed.     

Re-examining the overcapacity of the US lodging industry

Although the deteriorating profitability of the US lodging industry has been repeatedly attributed to overcapacity, there has been little research on the causes of overcapacity. The authors suspect that this issue stems from the lack of a working definition of optimal capacity level. This study evaluates the optimum capacity of the US lodging industry based on the fundamental price theory, which posits that prices are determined through equilibrium. Results of the simultaneous equations model show that the industry has an incentive to maintain overcapacity because the outcomes of under-capacity are even less desirable. The uncertainty of demand further encourages overcapacity to some extent. Historical overcapacity cycles in the US lodging industry suggest that overcapacity seems to be an outcome of unexpected demand shocks, rather than the consequence of irrational overbuilding. Implications for the industry and suggestions for future research are presented along with the study findings.     

Effects of service quality and food quality: The moderating role of atmospherics in an ethnic restaurant segment

This study empirically examined not only the relationship between perceived quality and satisfaction/loyalty, but also the role of customer perceptions of atmospherics in an ethnic restaurant segment. Specifically, this study, using hierarchical regression analyses, investigated the direct effects of service quality and food quality on customer satisfaction and loyalty as well as the moderating effect of the perception of atmospherics, in Korean restaurants. As expected, this study showed that service and food quality have positive and significant effects on customer satisfaction and loyalty. This suggested that, similar to other restaurant segments, employee service and food are of great importance for ethnic restaurants as well. Verifying the moderating role of atmospherics, however, this study found that good employee service can be more effective for increasing the satisfaction and loyalty of customers with a low perception of the atmospherics compared to those with a higher perception. Further, providing quality food is particularly critical for creating customer satisfaction in ethnic restaurants where atmospherics are not satisfactory. More detailed findings and implications are also discussed.
