| 1 | China's regional transport dominance: Density, proximity, and accessibility显示文摘Transport infrastructure plays an important role in shaping the configuration of spatial socio-economic structures and influences regional accessibility.This paper defines transport dominance from three aspects:quality,quantity,and advantage,measured by density,proximity,and accessibility indices.County is the basic unit for analysis.The results reveal:(1)Transport dominance statistically follows a partial normal distribution.A very few counties,1.4%of the total,have extremely high transport dominance which strongly supports the socio-economic development in these areas.In contrast,one eighth of all counties have poor transport dominance which impedes local socio-economic development to some extent. The remaining areas,about 70%of the counties,have median transport dominance.(2) Transport dominance is spatially unevenly distributed,with values decreasing gradually from the coastal area to the inland area.Areas in the first-highest level of transport dominance are mainly concentrated in the Yangtze River Delta,the Greater Beijing area,and the Pearl River Delta.Areas in the second-highest level are focused in Chengdu,Chongqing,and Wuhan metropolitan areas.Provincial capitals and a few other counties belong to the third-highest level. | JIN Fengjun WANG Chengjin LI Xiuwei WANG Jiao'e | 2010 | Journal of Geographical Sciences2010，20，2： | 58 |
| 2 | Location characteristics and differentiation mechanism of logistics nodes and logistics enterprises based on points of interest (POI): A case study of Beijing显示文摘后勤节点和后勤企业是核心搬运人和后勤空间的组织上的题目,并且他们的地点特征和区别策略具有到优化城市的后勤的关键重要性空间模式和保证合理资源分配。从 2014 年 12 月基于 Tencent 联机地图站台,兴趣(夏威夷人用芋头做成的食品) 的 4396 个后勤点在中国北京被收集。由工业集中评估和核密度分析的方法,在北京的后勤的空间分发模式被探索,在类型差别,供应要求方面因素和地点选择行为之中的相互作用机制被澄清,并且在交通的联合影响下面的空间区别的内部机制,陆地租金和财产被揭示。下列结论在纸被得出。(1 ) 后勤企业和后勤节点在地点展出合作凝块和空间分离的特征,并且后勤活动显示“闹市区区域,郊区和城市远郊的区域的边缘的区域”的空间模式,它与后勤雇用空格有弱联合度。(2 ) 也就是,后勤停的公共后勤空间和后勤集中,在政府的指导下面被生产,并且由后勤分发组成的终端后勤空间集中服务因为特定的工业和终端用户被企业统治。在后勤空间的二个模式之间的位置上的区别是重要的。( 3 )在后勤的形成空间地点,政府能由重新计划改变交通条件运输线路和运费驻扎地点,并且由增加或减少控制陆地租金和不同区域的可获得性后勤的陆地使用,影响企业行为并且形成后勤空格和函数区别的不同类型。在比较,后勤企业通过财产分配的区别遇见服务目标的多样的要求支持分割的专门化并且形成后勤空间的目标区别。 | LI Guoqi JIN Fengjun CHEN Yu JIAO Jinjuan LIU Sijing | 2017 | Journal of Geographical Sciences2017，27，7： | 11 |
| 3 | Understanding Relationship Between Accessibility and Economic Growth:A Case Study from China(1990–2010)显示文摘China′s economy and transport infrastructure have both experienced rapid development since 1978, and especially since 1990. Today, China is the second-largest economic entity in terms of GDP and has the largest high-speed rail(HSR) network and the second-largest expressway network in the world. This paper explores the relationship between accessibility and economic growth in China from 1990 to 2010. In the study, the basic research units include 333 prefecture-level cities and four municipalities. We explore a bivariate analysis framework of accessibility and economic growth, and their increase rates, to examine this relationship using long-term panel data. The results indicate that, first, accessibility and economic growth show a significant positive relationship using both cross-section and panel data, while the increase rate in accessibility and GDP indicate no significant relationship using cross-section data and a poor significant relationship using panel data. Second, the distributions of local advantage are uneven. Cities with low local advantage with respect to accessibility and GDP are mainly located in China′s eastern coastal region or the provincial capitals, while those with low local advantage in terms of their increase rates are located in the western region. Third, as China′s economic growth and transport networks have evolved, the distribution of local advantage shows little change in terms of accessibility and GDP, but a greater change in terms of their increase rates, which is largely influenced by the distribution of expressway and HSR networks. | JIAO Jingjuan WANG Jiaoe JIN Fengjun DU Chao | 2016 | Chinese Geographical Science2016，26，6： | 10 |
| 4 | CKIP-1 regulates macrophage proliferation by inhibiting TRAF6-mediated Akt activation显示文摘巨噬细胞在开发,动态平衡,织物修理和免疫起枢轴的作用。巨噬细胞增长被刺激殖民地的因素(M-CSF ) 导致了 Akt 发信号的巨噬细胞支持;然而,这个过程怎么被终止,仍然保持不清楚。这里,我们作为巨噬细胞增长的一个新奇禁止者识别酷蛋白 kinase 2-interacting protein-1 (CKIP-1 ) 。在放松巨噬细胞, CKIP-1 是在由组成地活跃的 GSK3β 的丝氨酸 342 点的 phosphorylated;, Akt 的下游的目标。这 phosphorylation 触发 CKIP-1 的 polyubiquitination 和 proteasomal 降级。在 M-CSF 刺激之上, Akt 被 CSF-1R-PI3K 激活然后使 GSK3β 失去活性;,导致 CKIP-1 和 β 的稳定; -catenin 蛋白质。β -catenin 包括 cyclin D 和 c-Myc 支持增长基因的表示。CKIP-1 与 TRAF6,为连接 K63 的 ubiquitination 要求的 ubiquitin ligase 和 Akt 的血浆膜招募交往,并且终止调停 TRAF6 的 Akt 激活。由这个工具, CKIP-1 在 M-CSF 刺激以后在迟了的阶段明确地禁止巨噬细胞增长。而且, CKIP-1 缺乏在老鼠自发地开发的 vitro 和 CKIP-1 −/− 导致增加的增长和巨噬细胞的减少的 apoptosis 巨噬细胞主导的脾大和 myeloproliferation。一起,这些数据证明 CKIP-1 由禁止调停 TRAF6 的 Akt 激活在巨噬细胞动态平衡的规定起一个关键作用。 | Luo Zhang Yiwu Wang Fengjun Xiao Shaoxia Wang Guichun Xing Yang Li Xiushan Yin Kefeng Lu Rongfei Wei Jiao Fan Yuhan Chen Tao Li Ping Xie Lin Yuan Lei Song Lanzhi Ma Lujing Ding Fuchu He Lingqiang Zhang | 2014 | Cell Research2014，24，6： | 7 |
| 5 | Transportation Development Transition in China显示文摘Scientific development is an invaluable asset to a country.Policies and development modes should be carried out based on scientific findings not only in industry,but also in transportation infrastructure construction.Building an integrated transportation system,which is in line with the national requirements of China and supports sustainable socio-economic development,is a key strategic issue related to building a moderately prosperous society and achieving realistic goals of a medium-level developed country.Based on a systematic review of the advances in China's transportation infrastructure over the last 60 years,this paper explores the main drivers of transportation development,including national policy,transportation structure,investment efficiency,and technological innovation.Analysis shows that China's comprehensive transportation infrastructure construction since 1949 can be divided into five stages initiated by these drivers,which correspond to four transition modes:policy transition,structural transition,efficiency transition,and technology transition.The transition path of China's transportation development shows that the dominant factors have changed,and the interval for each transition has shortened.With the implementation of the '12th Five-Year Plan',China's transportation infrastructure construction is showing some new characteristics and facing a new development transition.Finally,this paper analyzes the trends in transportation development in China and concludes that technological innovation will be the main driving force to increase the transportation supply and service area in the future. | JIN Fengjun DING Jinxue WANG Jiao'e LIU Dong WANG Chengjin | 2012 | Chinese Geographical Science2012，22，3： | 4 |
| 6 | Analysis of transportation carbon emissions and its potential for reduction in China显示文摘The transportation industry is an essential sector for carbon emissions mitigation.This paper firstly used the LMDI(Logarithmic Mean Divisia Index)decomposition method to establish factors decomposition model on China's transportation carbon emission.Then,a quantitative analysis was performed to study the factors influencing China's transportation carbon emissions from 1991 to 2008,which are identified as transportation energy efficiency,transportation structure and transportation development.The results showed that:(1)The impact of transportation development on transportation carbon emissions showed pulling function.Its contribution value to carbon emissions remained at high growth since 1991 and showed an exponential growth trend.(2)The impact of transportation structure on transportation carbon emissions showed promoting function in general,but its role in promoting carbon emissions decreased year by year.And with the continuous optimization of transportation structure,the promoting effect decreased gradually and showed the inversed'U'trend.(3)The impact of transportation energy efficiency on transportation carbon emissions showed a function of inhibition before pulling.In order to predict the potential of carbon emission reduction,three scenarios were set.Analysis of the scenarios showed that if greater intensity emission reduction measures are taken,the carbon emissions will reduce by 31.01 million tons by 2015 and by 48.81 million tons by 2020. | Jinxue Ding Fengjun Jin Yuejiao Li Jiao'e Wang | 2013 | Chinese Journal of Population,Resources and Environment2013，11，1： | 2 |
