利用调查采集到的113个闽东森林小镇资源点数据为样本,运用ArcGIS10.2地理信息系统分析工具对闽东森林小镇资源的地理空间分布展开研究。通过对最临近指数、核密度分析、热点分析、缓冲区分析的方法,得出闽东森林小镇资源空间分布特征:闽东森林小镇资源点总体分布呈集聚类型;资源点核密度和热点值分布明显,空间疏密上呈“中南密集、东西北稀疏”的格局,空间距离呈现先增加后减少的规律,并有明显的舒适范围,最后对闽东森林小镇建设发展提出理论思路。 相似文献

为洞察农业高质量发展的时空差异及演进趋势,基于2005—2019年中国部分省份数据,立足“新发展理念”从“创新、协调、绿色、开放、共享”五维度构建农业高质量发展评价指标体系,运用加入时间变量的熵值赋权法对农业高质量发展指数进行测度,并利用ArcGIS10.8软件、Markov链分析方法对农业高质量发展进行时空演变分析。研究结果显示:农业发展在创新、协调、绿色、开放及共享方面都取得显著成效;整体上,在考察期内农业高质量发展水平逐步提升,但地区之间差异明显;在时空演变上呈现不同的演化格局,具有东部地区领先,中西部地区发展相对落后和迟缓的时空演化特征。总体呈现向高水平等级演化的趋势但动态演进速度缓慢。因此,要持续推进农业科技体制改革,切实提升农业高质量发展水平。 相似文献

Motivated by the Saudi Arabian government's objective to diversify its economy away from oil and correct deficiencies associated with the Saudi stock market crash of 2006, a series of significant capital market infrastructure reforms were initiated that began with the 2007 reorganization of the Tadawul Stock Exchange (TSE) and the Capital Market Authority (CMA) as its sole regulator. This paper adds to the growing body of emerging market literature by providing new evidence of the effects of these initiatives on earnings quality for firms listed on the TSE. The results of tests of this study provide robust evidence that earnings quality increased during the 2007 to 2018 reform period. In particular, we document that relative to pre – reform years, reform period R squares, earnings response coefficients (ERCs) increased and discretionary accruals decreased. We rationalize these findings by asserting that improved regulatory oversight in juxtaposition with significant reform period investments into Saudi Arabia's capital markets infrastructure enhanced earnings quality (Jiambalvo et al., 2002; Latif et al., 2017; Zhong et al., 2017). 相似文献

This paper looks at the evolution of the Licensed Shared Access (LSA) – a pioneering European scheme for tapping into radio spectrum that remains assigned to incumbent users. Using the theoretical framework of Co-evolutionary Development, we build analytical case study to understand why this crucial innovation did not take hold in the European wireless market, despite a decade of regulatory and standardisation efforts. Drawing on literature analysis and expert knowledge, we identify barriers that contributed to the stalling of LSA deployment and co-evolutionary forces that could help alleviating them. We expose the need for more proactive engagement of European regional policymakers and suggest directions for refocusing future LSA regulatory activities to target an expanded set of frequency bands, as well as broadening their scope to include local non-public networks and industry verticals. 相似文献

Within emerging markets, institutional conditions vary significantly at both the country and subnational levels. Although the extant literature recognises the types of risk faced by multinational enterprises (MNEs) in emerging markets, it has hitherto paid scarce attention to explaining how MNEs manage such risk at the subnational level. Reporting on four case studies from Indonesia, we outline how MNEs ensure their success by maintaining active relationships with a variety of non-market actors—including opinion leaders, government officials, and communities at the subnational level. In our study, we developed a conceptual framework, showcasing how MNEs can manage socio-political risk within heterogeneous institutional settings. 相似文献

Although extant literature confirms the efficacy of 9-endings, how consumers perceive multi-digit prices with repeating identical ending digits such as $1999 is less clear. Research indicates that consumers tend to truncate 9-ending prices and associate them with discounts. Five experiments demonstrate, however, that consumers are likely to perceive multi-digit prices with 1-endings (e.g., $2111) as being more on a discount than prices with 9-endings (e.g., $1999). Moreover, a year-long field study shows that 1-ending (vs. 9-ending) prices receive more click-through rates when presented in online ads. These novel findings inform retailers on how they can generate higher discount perceptions by using 1-endings rather than 9-endings in multi-digit prices. 相似文献

This study aims to open the black box of heterogeneous responses to violent conflicts by focusing on subsidiaries’ operational exposure to violent conflict and their decisions to exit host countries. Drawing on real options theory, we propose a viable approach multinational enterprises can take when they encounter violent conflicts in their operating locations. Our analysis of 3,479 foreign subsidiaries operating in 11 countries over 26 years suggests that the exit decision of any given subsidiary located in a conflict-affected country depends on its operational scope. However, this effect depends on the characteristics of the operations the subsidiary undertakes, specifically, whether the subsidiary conducts natural resource-seeking operations and the degree of operational overlap with the same-parent affiliates. 相似文献
