[目的]开展土地综合承载力评价是科学编制国土空间发展战略的基础。通过构建包含水土资源承载力、经济承载力和生态承载力3个维度土地综合承载力评价指标体系,定量刻画郑州市城市土地综合承载力的特征与轨迹。[方法]运用均方差法,选取2010—2016年郑州市城市土地综合承载力评价指标,分析其土地综合承载力特征。[结果](1)总体上,郑州市城市土地综合承载力不断增强,水土资源承载力呈现先升—降—升的动态演变特征; 经济承载力持续增长,这源于郑州市土地经济效益的大幅提升; 生态承载力呈现波动性增强的演变特征。(2)郑州市城市土地综合承载力经历了较低—中等—较高发展历程,但土地综合承载力处于低层次的较高阶段,仍有较大提升空间。(3)为提高郑州市城市土地综合承载力,应加快“多规合一”规划的编制,科学划定城市增长边界和“三生”空间,转变城市发展理念,优化发展发展路径,提升城市土地综合承载力水平。[结论]郑州市城市土地综合承载力仍有较大提升空间,应加快建立土地综合承载力扩容的有效机制。 相似文献

We analyse the effect of a large scale infrastructure investment, namely the construction of the Oresund bridge, on the local and supra-regional economy. We employ the synthetic control method to construct counterfactual regions that mimic the trajectory of Malmo and Southern Sweden without treatment. Our results point to a positive effect. However, placebo tests in space and time only reveal statistical significance at a larger regional level. The results suggest that spillover effects are eminent. 相似文献

This research examines how the social servicescape (i.e., employee-customer, employee-employee and customer-customer) impacts brand-related outcomes via branded social cues. Informed by theories related to cue consistency and conceptual fluency, results from three experimental studies conducted across sectors and scales of hospitality businesses (i.e., luxury hotel, high-end restaurant and limited-service hotel), indicate that branded social servicescape cues have direct, indirect and interactive effects on brand-related outcomes. In luxury contexts, when the brand’s personality is absent in employee-customer social cues, the negative effects were buffered if brand personality is reflected in employee-employee social cues. Conceptual fluency mediated the relationship between branded employee-customer social cues and brand-related outcomes, which was moderated by branded employee-employee social cues. Conceptual fluency also mediated the relationship between branded customer-customer social cues and brand-related outcomes. This research sheds light on how hospitality firms can leverage branded social cues to enhance customer evaluation of the hospitality brand. 相似文献

[目的]分析评价江苏省现有农田保护经济补偿政策绩效与空间差异对建立完善长效的农业生态补偿机制和推动我国农业生态环境的可持续发展具有重要意义。[方法]以江苏省为研究区域,运用熵权-TOPSIS法,选取2010—2017年全省及苏北、苏中、苏南三个区域内11个指标,计算江苏省及三大区域农田保护经济补偿政策综合绩效值与经济、生态和社会效益单项绩效值,进行比较分析。[结果](1)江苏省农田保护经济补偿政策在2010—2017年8年综合绩效值由0189波动增长到0841,效果初现且具有较强推广价值。(2)经济效益绩效值以年均257%的增长率由0增长到1,效果最为显著,社会效益次之,生态效益自2013年后为绩效值中最低值,与前两项最大差距在05左右,反映出环境改善、农田质量提高效应远低于农户创收、社会公平效应,政策拟合度不高。(3)江苏省农田保护经济补偿政策效果存在空间差异,综合来看政策效果表现为苏南>苏中>苏北,苏南凭借经济优势在2016年和2017年的综合绩效值上比苏中苏北高出01、在经济与社会绩效值以002的差距领先且生态绩效值没有下降拐点,具有长效可持续性。[结论]现阶段农田保护经济补偿政策效果依赖地方政府经济实力,尚未形成良性长效机制,需从制度体系、环境经济手段、差别化补偿措施、农业补贴结构和宣传等5方面着手,推进农田保护经济补偿政策更好地服务生态环境。 相似文献

With the expansion of urbanization caused by the growth of population and industrial activities, the urban/city and suburban areas are facing a variety of environmental threats. Although more research and urban policy has advocated and practiced the development of green infrastructure (GI) to support urban sustainable environment, the evaluation framework for the development of GI for promoting environmental sustainability is still insufficient. Moreover, the Analytic Hierarchy Process (AHP) commonly applied in published literature, makes an unrealistic assumption of independent relationships among dimensions/criteria in decision making for satisfying the real-world problem. Therefore, the purpose of this study is to construct the evaluation framework, including four dimensions and related ten criteria, using a new hybrid-modified multiple attribute decision-making (MADM) model for developing and improving the GI for promoting environmental sustainability. This MADM model is combined with three different methodologies of MADM, including the Decision-Making Trial and Evaluation Laboratory (DEMATEL) for constructing the influential network relation map (INRM) to explore the complex influential inter-relationships and DEMATEL based on Analytic Network Process (DANP) for determining the influential weights with the VIse Kriterijumska Optimizacija I Kompromisno Resenje (VIKOR) for evaluating and presenting improvement strategies for six different GIs. The empirical study indicates that DEMATEL and DANP Results suggest that decision-makers should pay more attention to the improvement of Design (D4) and Materials (D2) in terms of dimensions when utilizing the GI to promote environmental sustainability. Because these dimensions are enhanced, Species (D1) and Energy (D3) will be improved in synchronization. From the perspective of criteria, five are key core criteria and need to be focused on first: increasing the green coverage rate (B9), utilizing sustainable materials (B4), using ecological engineering (B8), shaping species biodiversity (B1), and reducing energy consumption (B5). Modified VIKOR reveals that “grass swales” are a comparatively better choice among six GIs for promoting environmental sustainability toward achieving the aspiration level. Therefore, this MADM model is beneficial to provide a more convincing assessment framework and improvement strategies for the development of GI for promoting environmental sustainability. As a result, these modified MADM models can be shown more conveniently and reasonably than traditional methods such as traditional AHP or ANP method. 相似文献

旅游景区的管理与建设对旅游业的发展至关重要。然而,截至2019年7月底,全国有数百家A级景区由于管理与建设不善,受到摘牌、降级等处罚。对照《旅游景区质量等级的划分与评定》可以发现,被处罚的景区主要存在的问题:景区配套设施管理差、旅游交通不畅、游览设施与服务不健全、景区卫生差、景区市场吸引力小等。因此,政府必须与景区相配合,采取相应对策,强化景区建设与管理;提升景区资源、市场吸引力等,以扭转被动局面,推动旅游景区的健康发展。 相似文献

The sequence of informational cues and the level of distraction have an impact on the judgment of a product’s quality and preference. Two quasi-experimental studies (Ntotal = 340) investigate the influence of the force behind the processing of these cues – working memory (WM). Previous research found that, in the presence of a distractor, high WM individuals are more able to recall the initial cue, and thus derive their product judgment from the initial strong cue. Study 1 contradicts these findings and raises important methodological questions regarding the conceptualization of strong and weak cues. Specifically, commonly accepted strong cues (e.g., product reputation) might not influence consumers as expected. Additionally, in a sequence of product evaluation with high vs. low degree of experientiality, study 2 reveals that consumers tend to show a primacy effect that is stronger for higher levels of WM capacity. Moreover, in a sequence of assessing low vs. high degree of experientiality products, consumers reveal stronger recency effects, thus showing that WM reinforces this recency effect. Our findings have important implications for marketers by suggesting that consumers with high WMC are more able to process complex stimuli and retrieve previously presented information on a product quality. These consumers also have a higher tendency to retrieve more information from product scenarios with a high degree of experientiality. 相似文献
