北京市农村居民点用地特征与整理方向分析

研究目的：研究不同类型农村居民点的整理方向。研究方法：综合分析法,归类分析法和GIS方法。研究结果：（1）最新数据表明北京市农村居民点总计有3803个行政村,总用地面积1141 km2,空间特征差异显著;（2）依照规划城镇建设用地范围边界和规划控制范围边界,可以将居民点区分为圈内居民点、环内居民点和环外居民点;（3）三类农村居民点存在显著的不同特点,整理方向不同。研究结论：北京市农村居民点用地规模偏大,需要按照农村居民点的区位分布与特征采取差异化的整理模式,提升北京市农村居民点土地利用效率。

浙江省创新产出空间相关性及其影响因素研究

文章以浙江省11个地市作为空间研究单元,以大中型工业企业创新产品产值作为创新产出的衡量指标,对浙江省2003-2011年市际创新产出进行探索性空间数据分析,并对其影响因素进行实证检验。结果表明:浙江省创新产出空间集聚现象显著,基本呈现高—高集聚与低—低集聚特征,即创新产出存在显著的空间自相关性;第二产业比重对创新产出具有显著正向影响;创新环境对创新产出不存在显著影响;创新投入对创新产出具有显著正向影响,研发经费投入影响效应较大。     

数字图书馆发展中的问题和解决方法

随着信息技术的发展,数字图书馆应运而生,它具有检索方便、易于共享、形式多样、不受时间和空间限制等优势。我国的数字图书馆理论和实践起步较晚,目前仍然存在许多亟待解决的问题,如数字资料本身的缺陷难以克服;馆藏资源的评价指标不科学、不统一;检索平台搭建不够人性化,不适用;网络安全得不到保证等问题。本文具体分析了这些问题并提出了解决方法:加强标准建设、促进资源链接;加强检索平台个性化服务与功能建设;提高数字资源质量评估策略;保证网络安全;提高图书管理员素质。

Telecoupling mechanism of urban land expansion based on transportation accessibility: A case study of transitional Yangtze River economic Belt,China

Several studies have explored the drivers of urban land expansion (ULE), but disregarded the influence of distant spatial effect on ULE at a large regional scale. This study contributed to a tele-coupling relationship framework between spatial spillover of ULE and transportation accessibility to find the influence of distance spatial effect on ULE. Drawing upon land-use remote sensing data from 1990–2015 and transportation network data, this study assessed the relationship between transportation accessibility and ULE, and developed a second-order spatial autoregressive model (SO-SAR) to explore the spatial spillover mechanism of ULE in the Yangtze River Economic Belt (YREB). The results find that ULE exhibits a significantly positive spatial correlation when the connection criterion of accessibility is 2 h≤hour≤3 h. The SO-SAR model results show that ULE is affected by the historical ULE, which presents a significant path-dependence effect. Moreover, the ULE in most local cities has a weak inhibition on the ULE of the surrounding cities where the connection criterion of accessibility is 1 h. However, the spillover effects of remote city’s ULE have a slight positive impact on local ULE due to the improvement of traffic accessibility from 2005 to 2015. In addition, openness, labor flows, institutional hierarchy, and economic structure had a significantly positive effect on ULE during the period 1990–2015 in the YREB. Policy reforms are suggested to encourage the development of integrated transportation and urban land use at a large regional scale in China. Moreover, there is a need for a mindset shift from cities competing competition over land to cooperation between the cities in YREB.     

高管团队认知交互与创新绩效的关系：有调节的中介效应检验

在高度不确定的外部环境下，提高创新能力成为高技术企业增强竞争力的重要战略方向。既有关于不同认知层面与行为或绩效关系的研究，忽视了对动态环境下团队认知交互作用机制的思考。从认知视角出发，探讨了动态能力在高管团队认知交互与创新绩效间的中介作用、动态环境对动态能力与创新绩效关系的调节作用，以及动态环境对上述中介作用的调节效应。以长三角地区335家IT企业为研究样本，研究发现：①高管团队认知交互与创新绩效有正相关关系；②动态能力在高管团队认知交互与创新绩效之间具有中介作用；③环境动态性对动态能力与创新绩效的关系有正向调节作用；④环境动态性强化了上述中介作用。     

How being envied shapes tourists’ relationships with luxury brands: A dual-mediation model

Positive reviews of luxury brands on social media provide tourists with an opportunity for self-presentation. Recent studies have suggested that these reviews can easily trigger envy in receivers, yet few studies have discussed the effect of envy on review writers. This research examined the effects of review writers’ perceptions of being envied on their relationships with the luxury brands they shared on social media. The results of three experiments in vacation scenarios showed that writers were more likely to feel pride (anxiety) when they were benignly (maliciously) envied, eliciting a stronger (weaker) self-brand connection. Moreover, social tie strength played a moderating role. The effect of being envied was stronger when writers and receivers had strong (vs. weak) ties. Our findings provide luxury brand managers with managerial insights into content customization and platform selection in buzz marketing strategies.
