基于模糊综合评价模型的天津滨海新区城市生态系统健康评估

在分析城市生态系统健康评估研究进展的基础上,采用层次分析法建立城市生态系统健康评价指标体系,然后利用模糊数学模型,以天津市滨海新区为案例,进行城市生态系统健康评估。结果表明,近年来天津滨海新区城市生态系统处于亚健康状态,总体状况并没有明显改善。主要原因是在经济快速增长的同时,第二产业比重过高,能源消耗大量增加,环境质量较差,虽然投资力度加大,但仍有恶化趋势,未来改善压力大。如果不从整体上加大产业结构改善,加大环境保护和生态建设,将大大影响滨海新区的可持续发展。     

品牌社群生态位及其测量模型研究

近十五年来,在品牌关系理论研究的热潮下,Munizεt&O’Guinn提出的全新概念"品牌社群"(brand community)受到广大实践工作者和学者们关注,成为西方品牌理论研究的新前沿。本文在对为数不多的品牌社群理论进行综述分析的基础上,提出了从生态学生态位角度研究品牌社群的全新视角。通过对品牌社群生态位内涵进行界定,以及对前人有关品牌生态系统层级构建进行完善的基础上,从生态位宽度和生态位重叠度层面构建品牌社群生态位测量模型,即运用一维生态因子轴来分析品牌社群对资源变量的占用幅度以及共享状态,表征该类社群处于生态系统环境中的相对地位,目的在于对生态位重叠态势下的竞争格局预先作出有效判断,从而在提升品牌社群决策科学性的同时,提升企业顾客资产以及品牌资产的价值。

京沪高速铁路生态现代化的思考——基于区域生态系统项目的技术经济评价模型

京沪高速铁路生态系统建设将是中国东部六省市率先实现生态现代化的重大契机,正外部性效应是京沪高速铁路生态系统项目技术经济评价的主要特征,管理部门有必要定量测算其复合生态系统的生态正外部性并使正外部效应内部化.根据京沪高速铁路生态系统的收益应该等于其具有私人品属性的正产品收益和具有正公共品属性的副产品收益之和这一原理,可以设计京沪高速铁路生态系统技术经济评价的三个主要指标,它不仅可以用于其项目评价,而且从理论上为政府最大限度地支持生态系统的发展,提供一个定量测度的工具.     

基于动态能力的数字创新生态系统构建: 以华为汽车为例

企业通过创新主体网络协同,构建出价值共创的创新生态系统,以便在数字化时代感知并适应数字环境变化,为此需对数字创新生态系统的生成机理进行探究。以数字创新企业——华为汽车为研究对象,采用扎根分析法,基于动态能力的理论视角,研究华为汽车数字创新生态系统的构建机理和演化路径。研究发现：（1）数字创新企业构建出的数字创新生态系统历经三个阶段,拥有三条演化路径和四种能力。三个阶段为整合数字资源阶段、拓展数字资源阶段和共享数字资源阶段;三条演化路径为市场需求、跨界交流和网络协同的路径;四种能力为信息感应、资源整合、资源获取和资源重组能力。（2）数字生态环境和动态能力是推动数字创新生态系统不断演进的内在动力,使系统组织构架不断升级,派生更多创新主体,形成网络协同架构。研究结论对数字创新企业如何构建数字创新生态系统,具有理论性指导和实践价值。     

A new innovation paradigm: European cohesion policy and the retreat of public science in countries in Europe's scientific periphery

This article seeks to undertake a critical assessment of the changing position of public science in the entrepreneurial ecosystem of the countries on the periphery of European research. These countries are driven by new innovation paradigm based on entrepreneurship, which are implemented within the European Smart specialization strategy (S3). This article argues that S3 is widely implemented in the cohesion countries and, while it provides substantial resources for science, technology, and innovation, it fails to provide sustainability in the public research sector. This has direct implications for policies concerning innovation and entrepreneurial ecosystems. In order to prove the thesis, the article provides theoretical argumentation for emergence of a new innovation paradigm, driven by the rise of the entrepreneurial ecosystem, its incorporation into S3, and a consequent retreat of science policy in favor of entrepreneurial policy. The empirical analysis is focused on the funding trends seen in the business and public research sectors over the last decade (2008–2017), which have clearly shown that S3 has not contributed, despite expectations, to an increase in public expenditure for science. This signifies S3's neglect of public research within entrepreneurial ecosystems and challenges the ability of S3 to reduce wide disparities in research and innovation performance across the European Union. This ultimately endangers the innovation potential of the entrepreneurial ecosystem itself.     

Digital sport entrepreneurial ecosystems

The entrepreneurial ecosystems literature has increasingly explored network relationships between different stakeholders, as well as the role of context. This article addresses the challenge of including a sport context in the entrepreneurial ecosystem literature thereby contributing to the sport entrepreneurship literature by bringing insights from entrepreneurship ecosystem research. In‐depth interviews of football stakeholders in the sport entrepreneurship ecosystem are conducted in terms of understanding the emergence of digital sport start‐ups. The issues raised help explore the changing nature of digital entrepreneurial ecosystems to take into account new sport technological advances. Mixed embeddedness theory is used as the conceptual foundation to understand sport digital entrepreneurial ecosystems. Key management practices are identified in terms of sport start‐ups participating in entrepreneurial ecosystems. The article concludes by making suggestions for future research.     

Social media-based analysis of cultural ecosystem services and heritage tourism in a coastal region of Mexico

Understanding spatial patterns of visitation and benefits accrued to different types of natural and cultural heritage tourists may have important implications for the sustainable management of their destinations. We investigate cultural services accrued to local, domestic and international visitors to the Usumacinta floodplain, a coastal region with one of the highest biological and cultural diversities in Mexico. We combine analysis of social media photographs and high-resolution land cover mapping to identify different cultural services and their association with specific ecosystem and land cover types. Hotspots for international tourists are spatially restricted to well-known and accessible sites. Locals are 2.2–2.5 times more likely than international visitors to be associated with aesthetic appreciation and birdwatching. Locals upload more photographs of coastal lagoons, mangroves, beach and sea. Results are analyzed in light of land cover changes in the region and provide valuable information to decision makers for improved tourism management and conservation strategies.

动态能力理论视角下战略柔性对企业绩效的影响研究---差异化动态环境规制强度的调节效应

当前企业推进绿色转型进程、提升企业绩效,是实现高质量发展的重要途径。鉴于企业主动应对内外部因素联动影响的重要性,以动态能力理论视角,在探讨了企业变革发展驱动机制的基础上,尝试构建动态环境规制嵌入下的战略柔性与企业绩效的理论框架。分析并实证检验了战略柔性对企业绩效以及差异化强度的动态环境规制在二者关系中调节效应的作用机理和边界。研究结果显示,当前情境下,前瞻柔性、响应柔性对企业绩效均有显著的正向影响,且响应柔性的贡献度较高;两者交互效应亦能显著的正向影响企业绩效;表明企业对环境变化的预测、反应能力以及将两者协同配合是绿色转型发展的重要措施。一般强度的动态环境规制在前瞻柔性、响应柔性与企业绩效的关系中均不起显著的调节效应;高强度动态环境规制仅在响应柔性和企业绩效的关系中起显著负向调节效应;表明动态环境下,一般强度的政府规制政策对企业的决策和创新等行为更多的是无显著影响,充分尊重其自主发展;同时政府要根据环境变化,合理控制环境规制实施强度,谨防给企业应对环境冲击造成额外的负担。综合研究结果,提出企业加强多重柔性机制建设的力度和政府注重环境规制政策引导作用的策略,最终实现各利益相关者协同推进高质量发展的目标。
