The Doctrine of the Mean: Workplace Relationships and Turnover Intention

The present study examines the curvilinear relationships between LMX/TMX and team members' turnover intention simultaneously. That is, members with high LMX, TMX, or both are more likely to have turnover intention. Hypotheses were tested with a sample of 452 nurses, and we adopted the response surface methodology and polynomial regression to test our theoretical model. The hierarchical regression analysis showed that TMX has a U‐shaped relationship with turnover intention but not with LMX. In addition, the results indicate that both the congruence and incongruence of LMX and TMX result in higher turnover intention, but moderate levels of LMX and TMX have the lowest turnover intention. Strengths, limitations, practical implications, and directions for future research are discussed. Copyright © 2018 ASAC. Published by John Wiley & Sons, Ltd.     

高校新农村研究院：科技支撑乡村振兴的有效载体

[目的]较之前开展的新农村建设,乡村振兴战略是一种更高层次的发展手段和目标。文章旨在对高校新农村研究院推动乡村振兴的实践经验和困难问题进行梳理,分析背后的成因与制约因素,以期为以高校新农村研究院为抓手、从科技引领和支撑的角度推动乡村振兴战略的落地实施提供有针对性的建议。[方法]该文从协同创新理论出发,基于对沈阳农业大学新农村发展研究院的实地调研,采用文献梳理、归纳总结和定性分析等方法对高校新农村研究院为乡村振兴战略提供科技支撑的机理、模式、作用和困难问题进行了梳理。[结果]高校新农村发展研究院通过整合政府、高校、企业等多方资源,从技术协同、人才协同与理念协同3方面为乡村振兴提供了有效支撑。但目前各级政府对高校新农村研究院的作用地位还缺乏充分认识,存在财政支持不到位、技术推广激励与考评机制不完善等问题。[结论]整合各方科技创新资源,构建起各类主体跨界协同、不同技术集成应用、创新资源全链配置、关联产业融合发展的新型农业科技协同创新体系;进一步强化高校新农村发展研究院在农业科技服务中的主体地位,增强财政对新农村发展研究院的持续投入,改革高校农技推广人员职称评定与考核激励机制。     

Bank Income Diversification,Asset Correlation and Systemic Risk

This paper explores whether the asset correlations among the non-interest activities of banks are the key causes for enhancing the bank diversification-systemic risk nexus. Our empirical evidence indicates that banks' income diversification significantly raises systemic risk. After removing those banks with high asset correlations, the effect of individual banks' diversification on banking systemic risk turns insignificant or even inverse. The results show that high asset correlations among banks could introduce bank failures, thereby leading to higher systemic risk in the financial sector.     

政策不确定性、财政扩张与区域商业银行风险——基于中国地方官员变更和银行业的证据

文章利用2007-2017年我国93家区域商业银行的面板数据，并结合省级宏观经济数据和地方官员变更数据，实证考察了中国地方官员变更引起的经济政策不确定性对区域商业银行风险的重要影响。研究结果表明：（1）地方官员变更引起的政策不确定性增大了区域商业银行风险；（2）地方官员变更引起的政策不确定性，通过提高银行的资产收益率降低了商业银行风险；而不确定性时期的财政扩张，通过降低银行资产收益率增大了商业银行风险；并且财政扩张的负面影响大于政策不确定性的正面影响；（3）各省的市委书记发生职位更替引起的政策不确定性对区域商业银行风险的影响更大。文章研究为新时代背景下的金融供给侧结构性改革、政府宏观经济政策的制定以及财政体制与金融体制之间的联系提供参考。     

产业视角下环京津山区贫困县农业品牌建设路径研究*——以张家口市崇礼区为例

[目的]农业品牌建设是连接农业生产与市场消费的有效途径,是贫困地区特色农产品产销对接的重要抓手,在环京津贫困地区率先实现农业品牌建设的突破,示范意义重大。然而,针对贫困县的研究相对缺乏,农业品牌建设实践中脱离产业实际的问题比较常见,亟需路径探索。[方法]采用文献梳理、案例分析、实地和书面调研等方法,以张家口市崇礼区为例,对环京津山区贫困县农业品牌建设的现状进行分析,对路径与战略作出谋划。[结果]环京津山区贫困县的农业产业具有品质优势、错季优势和物流优势,受到资源短缺、投入不足、人才匮乏的限制,也面临居民消费升级、京津冀协同发展、产业扶贫等机遇。[结论]在产业视角下推进环京津山区贫困县农业品牌建设,应当重点实施品质农业发展行动,加强品牌营销,培育专业队伍,开展小而美、中高端、精准化的特色农业品牌建设。同时,建议上级有关部门在组织保障、政策倾斜、指导服务上给予有力支持。     

Income comparison and happiness: The role of fair income distribution

Relative income gap is one of the most popular approaches for explaining the income–happiness relationship. We argue in this article that when people compare their incomes, they care about distributional fairness more than relative income disparity. It is difficult for us to explain China's income–happiness paradox if we simply compare the income gap and do not explore the income‐generation process leading to income inequality. We therefore employ an approach based on a responsibility‐sensitive theory of justice that decomposes individual income into fair and unfair components. As a proxy for distributional unfairness, unfair income is considered the main source of unhappiness. Using data from the Chinese Household Income Project survey, we find strong support for the negative relationship between income unfairness and happiness. We also find a significantly positive relationship between the relative income gap and income unfairness, which leads us to consider the income comparison hypothesis as the explanation for the income–happiness paradox in a new light. Sensitivity analyses confirm the robustness of our results.     

The time‐varying performance of UK analyst recommendation revisions: Do market conditions matter?

This study examines the time‐varying performance of investment strategies following analyst recommendation revisions in the UK stock market, with specific emphasis on the impact of changing market conditions. We find a negative relationship between the recommendation performance and market conditions as measured in terms of past market return and market volatility. In particular, the upgrade (downgrade) portfolio generates significantly positive (negative) net abnormal returns in bad market conditions (e.g., the dot‐com bubble burst in 2000 and the credit crisis in 2007), but not in other periods of time. Moreover, our non‐temporal threshold regression analysis shows that the reported negative relationship disappears when market conditions become better, i.e., when the past market return (market volatility) is higher (lower) than a certain level, indicating the importance of taking non‐linearity into account in the long sample period as examined in this study. Our time‐series bootstrap simulations further confirm that the superior recommendation performance in bad market conditions is not due to random chance; analysts have certain skills in making valuable up/downward revisions in bad markets.     

股票流动性抑制了股价崩盘风险吗?

通过分析沪深A股上市公司2004—2018年的数据发现,股票流动性加剧了公司股价崩盘风险。经过多种稳健性检验并处理内生性问题后,该结论仍成立。另外,股票流动性加剧股价崩盘风险的效果在分析师关注程度较低和所在地区制度环境较差的企业中表现得更为明显。最后的机制分析表明较高的股票流动性通过提高机构投资者持股比例加剧股价崩盘风险。研究结论拓展了股价崩盘风险影响因素的视角,为合理引导股票市场流动性,防范未来的股价崩盘,维护股票市场稳定性提供了政策参考。
