［目的］通过对个性化的江西省乡村旅游区的空间分布进行研究,并对个性化的红色旅游资源进行评价,以期对乡村旅游的发展提供新的思考路径,建立具有个性化的乡村旅游体系。［方法］运用GIS102操作平台对江西省119个红色乡村旅游区的空间分布情况进行研究,通过计算最临近点指数、地理集中指数和核密度计算分析其空间分布特征。以资源要素价值、开发价值和社会效益组成评价层,下分14个指标,对江西省红色旅游资源进行评价研究。［结果］(1)江西省红色旅游区分布类型为集聚型,分布不均衡; (2)在评价准则层中,旅游资源要素价值权重最大,为0647 9,其次为社会效应,权重为0229 9,开发条件权重最低,为0122 2; (3)指标层权重排名前三位的依次为资源完整性、教育性和组织管理,权重值分别为0162 0,0116 5和0111 7。［结论］江西省乡村红色旅游区数量较多,但整体呈集聚型分布特点; 旅游资源要素价值权重最高,且整体资源禀赋较强,社会带动效应明显,具有极强的开发价值。     

四川省乡村旅游可持续发展水平测度

[目的]通过对四川省乡村旅游可持续发展水平进行研究,综合分析其生态环境、资源开发和经济社会之间的发展水平及影响因素,以期对四川省的乡村旅游可持续发展提供合理的参考建议。[方法]构建评价指标体系,以生态环境质量、资源开发情况、经济发展水平和社会发展水平4个方面20个具体指标构成评价综合层,运用层次分析法和模糊综合评判法系统分析四川省乡村旅游可持续发展水平。[结果]在综合评价层中,生态环境质量和资源开发情况的权重值分别为0.426 5和0.328 4,高于经济发展水平和社会发展水平的0.104 2和0.140 9。四川省乡村旅游可持续发展水平综合得分为85.48,为2级水平。[结论]四川省乡村旅游可持续发展水平处于中等,有较大提升空间;交通开发难度较大和旅游收入占GDP的比重较低,成为制约乡村旅游发展的主要因素;加强旅游基础服务设施建设,增加交通便捷性,培养一批高素质旅游服务人才队伍是四川省乡村旅游可持续发展的关键。

马克思主义经济学人本思想对财务学研究的启示与拓展

针对财务学的“经济人”假设进行了探讨,认为正是由于公司财务理论研究前提假定的非真实性,导致了当前主流财务学在研究导向、研究方法和研究对象上的失效。马克思经济学人本主义思想为财务学研究如何贴近社会现实提供了一个很好的借鉴思路。财务学本身具有社会属性,在此基础上,财务学研究的领域可以扩展到制度财务学、财务社会学、财务心理学、财务伦理学等方面。     

Whether to Abolish or Introduce Dual Regulation as Trade and Environmental Policy?

China, which has already introduced an environmental tax in an effort to decarbonize, has recently begun emissions trading and is using two environmental policies in tandem, but there are concerns about the impact on growth and trade. Trade and environmental policies affect firms' entry and exit, resulting in changes in aggregate productivity and pollution emissions. This study compares the impacts of single regulation and dual regulation on welfare, using a research-and-development based growth model with heterogeneous firms. Under single regulation, the cleansing effect of trade liberalization could be undermined. Under dual regulation, trade liberalization decreases pollution and improves average productivity whereas decreasing total permits reduces pollution. From the perspective of improving welfare it is desirable to choose dual regulation because trade liberalization can reduce total pollution emissions via the cleansing effect of trade liberalization.

Free‐riding in multi‐party alliances: The role of perceived alliance effectiveness and peers' collaboration in a research consortium

Research summary : Multi‐party alliances rely on partners' willingness to commit and pool their efforts in joint endeavors. However, partners face the dilemma of how much to commit to the alliance. We shed light on this issue by analyzing the relationship between partners' free‐riding—defined as their effort‐withholding—and their perceptions of alliance effectiveness and peers' collaboration. Specifically, we posit a U‐shaped relationship between partners' subjective evaluations of alliance effectiveness and their free‐riding. We also hypothesize a negative relation between partners' perceptions of the collaboration of peer organizations and their free‐riding. Results from a mixed‐method study—combining regression analysis of primary data on a major inter‐organizational research consortium and evidence from two experimental designs—support our hypotheses, bearing implications for the multi‐party alliances literature. Managerial summary : Free‐riding is a major concern in multi‐party alliances such as large research consortia, since the performance of these governance forms hinges on the joint contribution of multiple partners that often operate according to different logics (e.g., universities, firms, and government agencies). We show that, in such alliances, partners' perceptions have relevant implications for their willingness to contribute to the consortium's shared goals. Specifically, we find that partners free‐ride more—that is, contribute less—when they perceive the effectiveness of the overall alliance to be either very low or very high. Partners also gauge their commitment to the alliance on the perception of the effort of their peers—that is, other organizations similar to them. These findings provide managers of multi‐party alliances with additional levers to motivate partners to contribute fairly to such joint endeavor. Copyright © 2015 John Wiley & Sons, Ltd.     

Some predictors of SMJ article impact

Article impact is becoming an increasingly popular metric for assessing a scholar's influence, yet little is known about its properties or the factors that affect it. This study tests whether author, article, and methodological attributes influence the impact of SMJ articles, defined as summed counts of article citations. Findings reveal that authors having fewer, more‐often cited articles tended to have SMJ articles that received the most citations. In addition, whether an article appears in a regular or a special issue is not a stable predictor of its impact. Moreover, empirical articles that test primary data, control for more threats to internal validity, and have higher statistical power tend to receive more citations. Further, an article's long‐term impact oftentimes becomes apparent shortly after its publication. Overall, the findings provide new insights into the determinants of impact and its temporal qualities and help explain some of the differences between high and average impact articles. The findings also underscore the need for transparency between author publication strategies (article volume, impact) and the requirements of his/her institution. Implications for authors, reviewers, editors, and administrative evaluation are offered. Copyright © 2005 John Wiley & Sons, Ltd.
