研究目的:探讨自然生态空间用途管制政策是否对现有法律制度提出了需求与挑战,寻求相应的应对路径。研究方法:文献分析法和比较分析法。研究结果:自然生态空间用途管制政策不仅具有转化为法律制度的需求,而且对现有法律制度提出了新的挑战:管制要素从生态环境转向生态空间,管制权利从旁落转向衡平,管制体系从管理转向治理。研究结论:在借鉴国外生态空间用途管制法律应对经验的基础上,提出将"自然生态空间"概念及其用途管制政策转换成具体法律制度的应对路径:(1)树立保护和改善自然生态空间的法律理念,以支撑自然生态空间用途管制法律制度的构建;(2)制定《自然生态空间用途管制法》,以保障自然生态空间用途管制相关机制的顺利运行。  相似文献

从大气环境与城市竞争力的关联性入手,将大气环境风险、现状和治理纳入评价指标体系,基于组合权重的大气环境竞争力评价模型,对2013-2017年京津冀13个城市的大气环境竞争力水平进行了测评,并结合空间自相关分析和障碍度模型揭示了其空间效应及障碍因素。结果显示:京津冀城市大气环境竞争力存在明显的空间差异,呈"北部高、南部低、局部跳跃"格局,城市差距逐渐缩小;京津冀城市大气环境竞争力呈显著的空间集聚效应且存在正向相关性,空间分布格局相对稳定。  相似文献

Creative hotspots have become a key driver for urban policies to stimulate social, cultural, environmental and organisational growth of creative and knowledge-based clusters, districts and hubs. However, their functional and spatial characteristics vary due to their different evolving structure as new spaces of economic activity in different contexts. This article points to a consideration of new foci for both land use and urban economic policy through a mapping of formal and informal creative hotspots in Brisbane, Australia. The study found two distinctive development patterns: (a) earlier top-down approaches as instigated by national and international innovation policies, and; (b) recently emerging bottom-up spaces for creativity, knowledge and innovation practices. This study examines how formal creative strategies and emerging informal creative spaces shape cities and urban policies. The methodology comprises online data collection and a review of creative and knowledge strategies and implementation policies. Data was then analysed via multiple mapping techniques illustrating the spatial distribution of creative hotspots, formal and informal formations, scale and land use characteristics. The research findings consolidate our understanding of Brisbane’s creative ecosystem and suggest new urban policy mechanisms to better foster the interrelationship between top-down and bottom-up approaches in cities, that is, between formally planned and large-scale interventions and small-scale organic and informal creative activities.  相似文献

This mixed methods study investigated how value is created in the physical retail space and how the customer experience is influenced by digital technology. A cross-sectional survey, with both qualitative and quantitative components, was distributed across a heterogeneous sample of 832 customers. The results revealed an overarching model comprised of three interrelated clusters: customer, service provider, and digital technology. We propose that this model can be understood as a valuescape, where customers' specific goals, needs, and desires drive them to interact and co-create value with service providers in the physical retail space, with digital technology either enhancing or disrupting this value co-creation process. The results also show that the importance of aligning digital solutions with customers’ drives increases at the same pace as reliance on technology. The findings offer guidelines on how to utilize digitalization to leverage customer experiences and thus strengthen the attractiveness of physical retail spaces.  相似文献

ABSTRACT

Massive Open Online Courses (MOOCs) have grown significantly and globally in less than ten years. However, practices and research in tourism and hospitality MOOCs remain nascent. This study proposes the MOOC Components Framework with six groups of course components: scaffolding, lectures, networking, collaboration, assessment, and affirmation. Drawing on this framework and a case study method, the study analyses 18 tourism and hospitality MOOCs from higher education institutions. The results highlight that: tourism and hospitality MOOC offerings lack diversity; the forum is the preferred communication tool; social media are comparatively underused; the discontinuity of MOOC instructors needs attention; and finally, littless multilingual support is available.  相似文献

This paper presents an empirical account of a phenomenon that we refer to as the ‘reverse tragedy of the commons’ in open innovation. The name signifies the ‘under-exploitation’ of intellectual property (IP) under weak appropriability. The name is this graphic because the tragedy is costly, and can also render IP effectively worthless and block innovation in the short to medium term. We propose that the tragedy is borne out of the interaction between enterprise characteristics, a competitive setting and the framework that is set by the policy intervention. This finding is pertinent to policy-makers with regard to the design of research, development and innovation instruments, as well as managers who must determine how to implement open practices in innovation.  相似文献

开放式创新行为对提高企业创新绩效有显著影响。基于2012年世界银行调查数据,对中国企业开放式创新行为影响因素进行了实证分析。研究表明:①企业开放式创新行为在区域、行业上分布不均;②竞争对手情况、信息技术支持度、数据软件共享度、产品出口、产品销售范围等对研发合作有显著正向影响;③高管工作经历、竞争者数量、信息技术支持度等对企业创新开放度有显著正向影响。  相似文献

通过构建嵌入政府质量和科技创新因素的经济增长模型,利用中国30个省份2004~2017年的平衡面板数据,实证检验政府质量、科技创新对绿色GDP发展的影响。研究发现:中国绿色GDP存在显著的空间集聚性及明显的区域差异性。在经济权重矩阵影响下,不同地区的政府效率、市场化程度、公平程度和腐败程度对绿色GDP的影响不同,其中政府效率、公平程度能有效促进经济发展较好地区的绿色GDP增长,却会抑制比较落后地区绿色GDP的增长;市场化程度对大部分地区绿色GDP呈现促进作用;腐败程度对地区绿色GDP增长呈阻碍作用。科技创新对各地区绿色GDP均起到积极的促进作用。因此,提升绿色GDP发展水平不仅需要提高地方政府质量,为绿色GDP发展提供符合实际的政策指导意见,还需激活企业科技创新能力,为绿色GDP发展提供有力科技保障。  相似文献

The literature on open innovation (OI) is characterised by studies based both on large companies and small and medium-sized enterprises (SMEs). Among all, one of the less explored issues in SMEs is what impedes them to adopt OI. Thus, this paper has the threefold objective to identify which factors hinder the adoption of OI in SMEs, to investigate if different behaviours exist among SMEs in relation to these factors, and to understand if the same factors effectively influence the level of adoption of OI. Based on a survey on 157 Italian SMEs, we identified four main barriers (namely, ‘knowledge’, ‘collaboration’, ‘organisational’, and ‘financial and strategic’) and three profiles of firms, different in terms of innovativeness of the industries they belong to (knowledge intensive, medium-innovative, and less innovative) and hampering factors perceived (‘knowledge’, ‘financial and strategic’, and ‘collaboration’ and ‘organisational’ barriers). Moreover, we found that some of these factors effectively impede the adoption of the paradigm.  相似文献

随着中国经济快速发展和人口集聚,建设用地需求快速增加,土地供需矛盾日益突出,资源保护和管理的压力逐渐加大。中国经济已步入新常态,经济结构转型倒逼土地供应结构优化调整。发达国家城镇化发展阶段起步较早,在土地节约集约利用与管理方面积累了宝贵经验。结合中国城市土地利用现状,借鉴美国、英国、德国等发达国家土地利用与管理经验,可从盘活存量土地、提高土地供给精准度、建立多元化供地机制三方面实现土地节约集约利用及有效管理,促进供给侧结构性改革。  相似文献
