中国地理标志官方标志使用问题研究

地理标志作为一类新型知识产权,与货源标记、原产地名称、传统特色保证（TSG）等概念既有联系又有区别。地理标志官方标志属于认证性质的官方标志,在2019年地理标志专用标志整合之前,中国一直处于3种标志并存使用阶段。此次整合标志着中国在地理标志统一认定上走出了重要的一步,但仍存在整合不彻底、有关表述使用混乱、行政程序冗余、难以实现监管功能等问题。建议在专用标志“二合一”整合基础上,进一步整合农产品地理标志,统一不同文件中的表述,同时强化地理标志官方标志的监管职能,从而完善地理标志官方标志管理体制。     

基于案例推理的进口矿产品质量安全风险管控体系研究

进口矿产品质量安全监管,是海关服务国家经济发展、保障人民生命健康及财产安全的一项重要职能,随着新形势、新业态的发展,矿产品监管及通关“好与快”的矛盾问题更趋凸显,给海关高质高效履职带来了严峻的考验。对此以进口矿产品质量安全监管为切入点,在对该领域风险构成梳理分析的基础上,将案例推理技术与矿产品质量安全风险管控相结合,探索建立一种有效的风险预警和处置机制,以提升海关在进口矿产品领域的把关服务效能,也为其他国门安全领域建立风险防控机制提供有益的思路和借鉴。     

Where's the greenium?

In this study, we investigate whether investors are willing to trade off wealth for societal benefits. We take advantage of unique institutional features of the municipal securities market to provide insight into this question. Since 2013, states and other governmental entities have issued over $23 billion of green bonds to fund eco-friendly projects. Comparing green securities to nearly identical securities issued for non-green purposes by the same issuers on the same day, we observe economically identical pricing for green and non-green issues. In contrast to a number of recent theoretical and experimental studies, we find that in real market settings investors appear entirely unwilling to forgo wealth to invest in environmentally sustainable projects. When risk and payoffs are held constant and are known to investors ex-ante, investors view green and non-green securities by the same issuer as almost exact substitutes. Thus, the greenium is essentially zero.     

银行理财产品与金融稳定--基于银行间风险传染的仿真分析

理财产品业绩受市场波动影响加大,有可能与原有银行间风险传染机制共振、放大银行系统风险。基于此视角,本文将银行理财产品嵌入银行间风险传染模型,研究银行理财产品对银行间风险传染的影响。结果发现:(1)在模型假定的条件下,考虑理财产品后,风险传染引发的平均损失增加28.76%。(2)如果考虑破产银行对理财产品的信息传染,平均损失进一步增加17.5%。(3)在投资者敏感性、资产非流动性较高时,银行对理财产品进行救助可以有效抑制风险传染;但冲击较大时,救助则会造成更大范围的风险传染。     

The interplay between technology characteristics,R&D internationalisation,and new product introduction: Empirical evidence from the energy conservation sector

Developing marketable products based on proprietary technologies is the key to success in many firms, but it is still a big challenge. Factors explaining when technologies are more likely to lead to a marketable product are not fully understood yet. This gap calls for further research on this important topic. The present paper addresses this issue by focusing on specific characteristics of technologies - i.e., their nature as breakthrough technologies and their generality - which can be considered as suitable predictors of new product introduction (NPI). Specifically, we study if and how these characteristics affect the likelihood of NPI. Moreover, in our research model, we argue that the effects of technology characteristics on NPI are contingent upon the degree of a firm's R&D internationalisation. We examine this moderating firm-level factor in a cross-level study design. We develop several hypotheses and test them with objective patent and novel trademark data. In detail, the analyses are based on a unique and longitudinal sample of 11,385 patents and 1,783 trademarks registered at the USPTO in the energy conservation sector by 696 different companies. By adopting hierarchical linear modeling (HLM), we reveal that the likelihood of NPI is positively related to the breakthrough nature of technologies; this effect turns negative when the level of breakthrough nature is very high. Instead, technological generality has a negative influence on NPI. Finally, the degree to which firms internationalise their R&D activities negatively moderates those relationships.     

An integrated arterial coordinated control model considering green wave on branch roads and pedestrian crossing time at intersections

Urban fine management needs scientific traffic management methods and efficient signal control programs. Green wave control is usually used to facilitate the unban traffic. However, maximum bandwidth optimization on arterial traffic signal timing is usually yielded from the sacrifice of the branch road. The green wave on branch roads and pedestrian crossing time at intersections are often neglected. In this paper, an extended integrated green wave control method is presented to solve the coordinated control issue, which considers green time constraints to ensure necessary time for vehicles on branch roads and pedestrian crossing time at intersections. Non-coordinated phase saturation is first introduced to describe the green time on branch roads. Next, the arterial roads are partitioned to enlarge the green wave bandwidth and an extended green wave optimization model with green time constraints is proposed. Combined with the green wave searching method, an improved genetic algorithm is applied. Finally, a real-world case study in Shenzhen, China, is employed to assess the model. Results show the proposed model can (1) reach the same public green time as in the traditional method and (2) increase the average sub-green wave bandwidth to improve the signal control.     

The green B&B promotion strategies for tourist loyalty: surveying the restart of Chinese national holiday travel after COVID-19

This paper attempts to empirically analyze green/healthy B&B promotion strategies for tourism recovery after the first wave of COVID-19. The survey will be meaningful in the real world of B&B tourism recovery, and it was conducted during the first Chinese national holiday without travel restrictions. China was the first country to resume travel after COVID-19. Confirmatory factor analysis (CFA) and structural equation modeling (SEM) were used for testing. The relationships observed among the green/healthy physical environment, well-being perception (WBP), tourist satisfaction (TS), and tourist loyalty (TL) provide a better understanding of how to support sustainable tourism recovery. Green/healthy B&B promotion strategies that focus on a green/healthy physical environment after the health crisis can also be employed in other countries and regions experiencing the same situation.     

Investigating beliefs,attitudes, and intentions regarding green restaurant patronage: An application of the extended theory of planned behavior with moderating effects of gender and age

This study aims to identify customer belief structures underlying the cognitive process of green restaurant patronage by applying the extended theory of planned behavior (TPB). The extended TPB model includes two additional predictors (past behavior and dining frequency) and two moderators (gender and age) to predict customers’ intention to visit green restaurants. This study followed recommended two-phase survey procedures. Salient beliefs of the target population were elicited in the first phase, and the relationships between those beliefs and other TPB constructs were analyzed in the second phase. Perceived behavioral control emerged as the most significant determinant followed by attitude and subjective norm in the Korean green restaurant context. The findings support the inclusion of past behavior as an additional predictor and confirm the moderating effects of gender and age. This study provides useful implications for effective marketing strategies for green restaurants.     

A multilevel investigation of the link between ethical leadership behaviour and employees green behaviour in the hospitality industry

The present study develops a multilevel model that examines the effects of supervisory ethical leadership behavior at the team level on employees green behaviour mediated by CSR at the organisational level, employees well-being, and taking responsivity at the individual level. Data were collected from a sample of 936 supervisors and 2284 employees from 184 hotels in United Arab Emirates. Utilizing multisource data and multilevel path analysis, the results indicated that supervisory ethical leadership behavior has indirect effect on green behavior through CSR, employees-wellbeing and taking responsibility behavior. These findings provide important implications for ethical leadership-green behavior link by developing and validating a multilevel model empirically in the hospitality industry.
