基于气候区划的中国建成区绿地率 区域差异研究

气候是影响城市绿地的基础性自然因素,定量研究气候对建成区绿地率的影响,利于合理调控城市绿地建设。以中国县级市及以上城市为样本,综合运用标准差、变异系数和锡尔系数等方法,探究1996—2015年不同气候区划建成区绿地率区域差异状况。结果表明：1)从发展水平看,不同气候区划具显著差异,热带高于温带,湿润、半湿润区高于半干旱、干旱区,其中,热带与湿润区、半湿润区城市重合度高,是气候优势区位;2)从差异度看,不同气候区划差异度具明显区别,温带差异度高于热带,干旱、半干旱区高于湿润、半湿润区;3)从差异分解看,温度带间建成区绿地率不平衡对全国总差异的影响度大于干湿区间,温度带间差异是我国总体差异的主要原因。以期为揭示气候对城市绿地建设水平的影响作用提供理论依据。     

近代中国海外游记研究综述

从上个世纪八十年代以来,随着改革开放和"文化热"的兴起,学界开始重视对近代海外游记,包括海外旅行的研究,从资料整理到论著、论文,面世了很多新成果,再现了近代中国历史变化的另一个侧面,推动了中国近代历史研究的深入.然而,其研究也有不尽如人意的方面,如大多的研究仅仅停留在客观叙述之上,缺少理性分析;资料整理亦不够全面.所以,学界当加强这项课题的研究.     

中西信用文化的比较与接点

中西信用文化有同有异.相同点在于中西方信用地位同样凸显,传统内涵基本相同,对信用同样重视;不同点在于观念、性质、范围和手段差异.中西现代信用文化有道德、经济、法律、技术四个方面的接点.借鉴西方社会信用建设经验,有助于我国更好地完善现代社会信用管理,建立与国际接轨的信用体系.     

中国宏观经济形势与政策:2009—2010年

本文依据中国经济增长与价格形成理论模型以及CMAFM计量模型,分析与预测2009—2010年间中国经济在积极财政政策和适度宽松货币政策支持下的复苏过程。本文认为,中国需求管理应该继续采取扩张性政策取向,完成中国经济景气从萧条到繁荣的周期形态转换,并且与中国经济发展的高储蓄—高投资—高增长模式相适应,形成以促进国内投资需求为轴心的政策架构。

The Geography of Innovation in China and India

The BRICS countries in general, and China and India in particular, are now widely regarded as the areas of the world likely to challenge the economic leadership of the United States (US) and the European Union (EU). A large part of this challenge will come from rapid technological catch‐up by China and India. Yet, despite a recent rise in interest, there is limited knowledge about how and where innovation takes place in these two leading emerging countries and to what extent the Chinese and Indian territorial systems of innovation differ from those in the EU or the US. In this article we explore the geography of innovation in China and India, concentrating on understanding key territorial‐level innovation trends by country, region and technology field, using the US and the EU as benchmarks. We find significant contrasts between the geography of innovation in China and India and that of the US and the EU. First, the degree of concentration of innovative activities in both countries is extremely high. Levels of agglomeration of innovation in the coastal provinces of China, as well as in Delhi and the South of India, significantly exceed the levels of agglomeration found in the USA and the EU. Secondly, China has witnessed a more rapid increase in the degree of concentration of innovation than India. We posit that the differences in the geography of innovation between, on the one hand, China and India and, on the other hand, between these countries and the developed world are rooted in different institutional settings, different systems of innovation and different national innovation strategies.     

Career self-management behaviour of Western self-initiated expatriates in local organizations in China

The available literature on self-initiated expatriates (SIEs) is generally based on the assumption that SIEs are protean in character and manage their careers independently. The current qualitative empirical study offers an alternative to this assumption, using 23 interviews with Western SIEs employed by local organizations in China to examine how and why SIEs target obtaining a labour market fit through career self-management behaviour, particularly in culturally distant career contexts. The assessment of the career self-management behaviour of Western SIEs was undertaken using King's framework (2004). Three approaches to self-management behaviour were identified based on the motivation and outcome expectations of SIEs: labour market entry, employability maintenance and career advancement. The research illustrates the flexible and dynamic nature of career self-management behaviour and reflects individuals' revised career expectations and the employment context of the host country. The findings contribute to the extant theory on SIEs by illustrating emerging means of realizing international careers in cross-cultural career contexts, and the significance of third-party initiatives supporting expatriation facilitated by the Internet and social media.     

基于GIS栅格尺度的我国冬小麦生产潜力研究

小麦在我国粮食安全和农业发展中地位重要,冬小麦是我国播种面积最为广泛的小麦类型,产量占全国小麦产量的90%以上,科学估算冬小麦生产潜力是合理制定小麦发展战略、挖掘小麦增产潜力、保证粮食生产能力的基础工作。本文利用AEZ模型,在GIS支持下将土地利用数据、气候观测数据、作物属性数据综合集成,对冬小麦不同层次的生产潜力及其空间分布进行1km×1km栅格尺度的估算和评价,为我国农业生产和小麦发展战略提供基础信息和科学依据。     

Jointly issued notes: a financial instrument to improve SME credit worthiness in China

A financial instrument to improve the credit worthiness of small and medium enterprises (SMEs), i.e. Jointly Issued Notes (JINs), improves the average credit rating of SMEs by eight notches, from BBB to AA+, thus reducing borrowing cost by 298 basis points. This research note describes the various kinds of JINs, and then analyzes their effect on the credit worthiness of SMEs. We conclude that the JINs successfully facilitate access to credit at lower rates in China.     

中国西北地区环境规制强度与城镇化质量的协调性分析

以西北地区为例,探讨环境规制强度与城镇化质量的耦合协调发展关系及其主要障碍因子,以期为促进二者协调发展和经济高质量发展提供参考。在构建环境规制强度与城镇化质量评价指标体系的基础上,运用熵值法、耦合协调模型和障碍度模型对西北地区环境规制强度与城镇化质量的综合发展水平、协调发展水平以及主要障碍因子进行分析,结论如下:第一,环境规制强度与城镇化质量综合得分整体均呈上升趋势,其中后者综合得分及其增长幅度均比前者要高;第二,环境规制强度与城镇化质量的耦合协调度较低,基本位于过渡区间并且多数是环境规制滞后类型,同时两者的协调发展水平整体呈稳步提升趋势;第三,影响环境规制强度与城镇化质量协调发展的障碍因子主要位于环境规制强度系统内。基于此,提出生态理念先行、制度保障紧随、产业升级并行的对策建议。
