欠发达农区农村居民点内部用地结构演变研究

[目的]从农村居民点内部用地结构演变视角,探索中国快速工业化和城镇化进程中的欠发达农区土地利用转型。[方法]以江西省吉安县凤凰镇铺前村为研究区,采用参与式农村评估、GIS与遥感影像相结合的方法复原了1986年、1996年、2006年和2016年农村居民点内部土地利用状况,揭示了农村居民点内部用地数量结构、空间结构和功能结构演变特征。[结果]30年来铺前村农村居民点用地规模先后经历了快速扩张、加速扩张及缓慢扩张3个阶段,用地类型以住宅用地为主,同时出现了一定的多元化发展趋势;农村居民点内部用地空间结构先后呈现蔓延扩张、跳跃式扩张、填隙式扩张模式发展特征;农村居民点内部用地的功能结构演变特征是农业生产功能逐渐弱化,出现微弱的非农生产功能,生活功能虽然经历稳定弱化和加速弱化过程,但是仍是主导功能,生态功能在中后期因内部用地竞争而明显弱化。[结论]通过系统的研究,揭示了30年来铺前村农村居民点内部土地利用结构演变特征,为优化农村土地利用,促进乡村振兴发展提供参考。     

京津冀城市群土地经济密度时空格局演变与驱动因素分析

[目的]研究2006—2016年京津冀城市群土地经济密度的时空格局演变特征及其驱动机制。[方法]以京津冀城市群153个县区为例,运用空间自相关分析、热点分析、地理探测器等研究方法,对土地经济密度的时空演变规律及其驱动因素进行探讨。[结果](1)2006—2016年京津冀城市群县区和地市的土地经济密度及其发展速度在空间上均呈"东高西低,南高北低"格局,但随时间变化区域差异逐渐缩小;(2)Moran′s I指数由0.013 9上升至0.065 3,表明在空间上存在空间集聚状态,且随时间不断优化,区域一体化趋势逐渐增强;(3)空间集聚特征明显,热点显著区集中于北京、天津等经济优势区,并向四周梯度扩散;(4)人均GDP、当年实际使用外资额、固定资产投资额等经济类因子对土地经济密度的解释力较大,且任意两因子交互后作用力优于单项因子作用力。[结论]可为京津冀城市群土地资源的合理利用和差别化调控提供参考。     

Local integration and co‐evolution of internationalizing Chinese firms

This study investigates the integration of internationalizing Chinese firms into local host markets. We explore the market‐driven investment of a new wave of Chinese private and local state‐owned firms in Australia since 2012, which has replaced the initial large‐scale investment in resources by central state‐owned enterprises. Using an in‐depth analysis of nine Chinese firms operating in various sectors of the Australian market, we argue that market integration, adaptation, and bilateral institution‐building through co‐evolution and empowerment of local subsidiaries of Chinese multinational enterprises results in entrepreneurial autonomy and characterizes a new generation of Chinese investors. We propose that Chinese multinational subsidiaries have transferred domestic practices to the Australian market and have reconfigured domestic and host market resources to gain a competitive advantage in their original investment industry and new industries. Our study advances middle‐range theory building and provides a practical understanding of the strengths and weaknesses of Chinese investors, their potential to disrupt local markets, and their responsiveness to market‐oriented institutional guidance. The results of this study suggest that the bilateral institution‐building and resource reconfiguration capabilities of Chinese enterprises can be transferred to other developed and developing markets, including Belt and Road Initiative countries.     

京津冀城市大气环境竞争力评价

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。     

Competing technologies and industry evolution: The benefits of making mistakes in the flat panel display industry

This article investigates the post‐entry implications of pre‐entry technological choices made during the uncertain period before a dominant design. Building on work on technological dynamics and organizational inertia, I argue that too early commitments to the winning technology may impede the ability to bring the best product to market, but delaying investment too long limits the ability to accumulate useful knowledge. Using data from the evolution of the flat panel display industry from 1965 to 2005, the study shows empirical support for the two theoretical mechanisms and offers the surprising result that firms starting in the losing technology before switching outperform other firms in terms of product value. Switching, while difficult behaviorally in recovering from failure, both delays difficult‐to‐reverse technological commitments and develops market knowledge.

The evolution of tourist arts

Tourist arts with ethnic content are at the nexus of changing tourism, ethnicity and art in the modern world. This paper explores the range of varieties of tourist arts, the dynamics of change between various types of artifacts, and the interaction between tourist arts and notions of ethnic self-perception. The analogy between language and art is pursued to illuminate the nature of the various communication codes embodied in tourist and ethnic arts. The paper concludes by stressing that tourist arts are not an end-point, but one possibility within the fluid relationships between material symbols, outsiders' demand, and the defense and reformulation of ethnicity. It also concludes that the evolution of ethnic awareness, combined with increased education and travel opportunities, is bringing a uniformity of attitudes towards tourism, material heritage, and museums among the middle classes of all nations. Thus minority ethnic symbols have become the manipulated “totems” of touristic identity.     

时空协同视角下的义乌中国小商品城演进历程分析

集贸式市场组织是一项极具“中国特色”的诱发性制度创新,是以某个固定场所为集聚地,以众多企业和个体商户为经营主体所形成的共享式交易平台。近年来,我国集贸式市场的组织形态及其功能都发生了重大变化,出现了与博览会、连锁经营、电子商务等现代流通业态相融合的趋势。在一个充分竞争的市场环境中,市场组织演进的结果体现出经济效率导向的要求。交易者将随着市场环境的变化,调整交易时间配置和空间分布的组合,以求达到交易成本最小化。本文以义乌中国小商品城为实证对象,以时间配置和空间分布为分析维度,运用交易费用经济学的理论方法,研究我国集贸式市场组织演进的动态过程。

供应链演化的内涵及其机制研究

供应链是由关联企业群体组成的复杂经济系统,其演化是一个由自组织与环境适应混合作用的系统演化过程。衡量供应链状态改变的标准是链中的核心企业。供应链演化包括两个层次:即供应链与环境相互作用和供应链内部自组织作用;创新是演化的内在动力,学习、知识信息共享、要素正常流动等都起着很重要作用;差异、选择、维持是供应链演化中主体间相互作用的根本机制。
