宏观审慎政策、经济周期与银行风险承担*

本文基于中国227家商业银行2005－2016年非平衡面板数据,实证检验中国宏观审慎政策实施对于银行风险承担的影响。结果表明：宏观审慎政策增强会在一定程度上抑制银行风险承担,而且这种显著的负向关系并不随着银行风险代理变量、经营辐射范围以及是否有外资入股等条件的改变而发生变化。经济周期会对宏观审慎政策的有效性产生非对称性影响,即相比在经济上行时期,在经济下行时期的宏观审慎政策对银行风险承担的抑制作用更强且更为显著。就可能的影响机制而言,本文发现宏观审慎政策通过提高银行盈利能力,从而降低银行风险承担。

DISTANCE‐SEGMENTED RURAL TOURISTS

This article uses travel distance to segment rural tourists in a tourist destination in the U.S. Midwest. A distance decay pattern was identified, with more than half of the respondents traveling from a location within 200 miles of the destination. The differences in the socio‐demographic, trip‐related characteristics, and destination activities of these tourists were examined across distinct distance segments. Among other findings, the study revealed that tourists from within a 50‐mile radius participated in most of the activities, and those traveling between 200 and 600 miles made up the majority of business travelers. These two segments also had a higher participation rate in the recreational activities than did the other distance segments. The findings of the study show that simple variables such as distance travel remain viable for destinations, particularly those in the rural area, to understand the tourists for segmentation purpose.     

Travel motivations and destination choice: A study of British outbound market

Abstract

Knowledge of people's travel motivations and its association with destination selection plays a critical role in predicting future travel patterns. The objectives of this study were to uncover the underlying push and pull factors of motivation associated with British outbound pleasure travelers as well as to identify key motivational factors that have significant effects on destination choice. Six push factors and five pull factors were found. “Knowledge seeking” and “cleanliness & safety” were perceived as the most important push and pull factors respectively. The results of logistic regression analyses snowed that the British tend to visit the U.S. for “fun & excitement” and “outdoor activities,” Oceania for “family & friend togetherness,” and Asia to seek a “novel experience.” The findings of differential motivational factors across seven destinations suggest that a destination can capitalize on its strengths with an optimal combination of push and pull factors to attract and retain the British travelers.     

The U.S. tourists’ perceptions of destination China over two transformative periods

This study conducted a textual analysis of The New York Times to examine the U.S. tourists’ perceived image of China as a destination by comparing the two periods of January 1980–May 1989 and January 2005–December 2015. The study found a drastic shift of the U.S. tourists’ affective image of China as a destination from being favorable and positive in the early period to being unfavorable and negative in the recent period. The affective image was characterized by the two domains of Exoticism and Sense of Superiority in the 1980s, as compared to the two domains of Ordinary and Negative National Image in the recent 10 years. Paradoxically, such a sentimental shift on the part of the U.S. tourists occurred while their perception of China’s destination attributes either did not change or grew more positive.     

全球价值链嵌入与制造业国际竞争力提升分析——基于创新型人力资本的作用效应

运用世界投入产出数据库(WIOD)的数据,分别对中国制造业16个细分行业的全球价值链(GVC)嵌入程度、创新型人力资本以及国际竞争力水平进行测算,实证检验了GVC嵌入对制造业国际竞争力水平的影响以及创新型人力资本对该影响的偏效应。研究发现:一是现阶段中国GVC嵌入能促进制造业国际竞争力水平提升,且存在着创新型人力资本的门槛效应;二是创新型人力资本削弱GVC嵌入对制造业国际竞争力水平的积极影响;三是前向价值链嵌入的创新型人力资本能够削弱前向嵌入对制造业国际竞争力水平提升的负向作用,而后向价值链嵌入的创新型人力资本在价值链后向参与时无法发挥显著积极作用;四是只有高技术行业的创新型人力资本能显著加深嵌入GVC对高技术制造业国际竞争力水平的正向影响。     

国有资本经营预算与收益管理问题的思考

根据党的十六大和十六届三中全会的要求,国务院常务会议决定从2007年开始在中央本级试行国有资本经营预算,表明国企将结束13年不向政府分红的历史,这是党中央促进经济发展的一项重大战略举措。本文从规范和加强国有资本经营收益收缴管理的必要性人手,围绕国有资本经营收益分配制度的演变、国有资本收益收缴管理的法律制度依据和原则以及目前国有资本经营收益管理存在的问题等进行了论述,并对如何做好国有资本收益收缴管理工作提出了相关建议。     

Optimal Licensing Policy under Vertical Product Differentiation

This paper explores a vertical product differentiation model with a licensing arrangement between a multinational firm with superior technology and a domestic firm with obsolete technology. We find that a subsidy provided by the domestic country's government to the domestic firm to assist with the licensing arrangement is welfare enhancing for the domestic country. Furthermore, both the multinational firm and the domestic country are better off under royalty than under fixed fee licensing. These findings stand in contrast to earlier results in the literature.
