它的总代理制模式大大提高了楼盘的出租率,许多代理商开始越来越依赖它理想阳光是一家写字楼服务提供商,但它并不直接为求租办公室的客户服务,而是一手抓住大量楼盘资源,一手抓住许多二级代理商,自己做起了B2B生意。这种模式被杨乐涛称为总代理制,跟写字楼行业传统的独家代理或者二级代理很不相同。 相似文献

By the end of World War I successive merger waves had producedan oligopolistic, tightly cartelized, English banking system,which was widely viewed as having restricted lending to small-medium-sizedfirms—the famous Macmillan Gap in industrialfinance. We explore the reasons behind the failure of marketentry to bridge this gap. The clearing banks are shown to haveacted as jealous monopolists, obstructing theactivities of the Credit for Industry Ltd (CFI), the only significantfirm established to breach the gap (rather than narrow its upperlimit). By poaching many clients it had vetted and approved,the banks blocked CFI's growth, deterring further market entry,and thus, preserving their monopoly position. 相似文献

This study analyses fatal crash patterns, and identifies the risk factors contributing to motorcycle versus non-motorcycle fatal crashes using binomial logistic regression on two-, four- and six-lane National Highways (NHs) in India utilizing police fatal crash data. The distribution of victims’ mode by striking vehicles shows that percentage share of striking vehicles (truck) against the victims’ vehicles (motorcycle) is 44%, 52% and 37% on two-lane NH-8, four-lane NH-24 and six-lane NH-1, respectively. Nine explanatory variables pertaining to fatal crash, victim, roadway and environment are considered for the model (using combined data of cited three NHs). The results of the logistic regression model (motorcycle versus non-motorcycle fatal crashes) show that for variable ‘collision type’, likelihood of occurrence of ‘rear-end’, ‘sideswipe’ and ‘head-on’ fatal crashes are 42-times, 35-times and 25-times more than ‘hit pedestrian’ respectively. Similarly, for variable ‘number of vehicle’, likelihood is thrice as ‘single-vehicle’ than ‘two or more vehicles’; and, for variable ‘number of lane’, probability is more on ‘two-lane’ NH-8 than ‘four-lane’ NH-24. Based on the study results, it is recommended to upgrade two-lane (undivided carriageway) to four-lane (divided carriageway) NHs to reduce ‘head-on’ collision. 相似文献

20世纪末期,中国中央政府启动了雄心勃勃的“五纵七横”国道主干线建设计划,将主要城市和重要口岸联结成网.这些干线自2001年起陆续通车,至2007年基本实现全部贯通.本文将国道主干线对西部地区的覆盖视为一次“交通干预”,以县级区划为观测单元,考察服务业就业占全社会就业的份额如何对“交通干预”做出因果响应.识别策略考虑了县域初始条件的异同性和交通外溢性干扰.经验估计表明,国道主干线贯通对其过境县域的服务业就业份额在整体上具有显著的提升效应,这种效应在城市地区明显高于农村地区,同时也因县域服务业就业的初始状况而有所差异. 相似文献

Globalisation is blamed for many socioeconomic shortcomings. I discuss the consequences of globalisation by surveying the empirical globalisation literature. My focus is on the KOF indices of globalisation that have been used in more than 100 studies. Early studies using the KOF index reported correlations between globalisation and several outcome variables. Studies published more recently identify causal effects. The evidence shows that globalisation has spurred economic growth, promoted gender equality and improved human rights. Moreover, globalisation did not erode welfare state activities, did not have any significant effect on labour market interaction and hardly influenced market deregulation. It increased, however, within‐country income inequality. The consequences of globalisation thus turn out to be overall much more favourable than often conjectured in the public discourse. 相似文献

关于市场细分的四点思考 总被引:1,自引:1,他引:1
<正>市场细分的概念是美国市场学家温德尔·史密斯(Wen-dell R.Smith)于20世纪50年代中期提出来的。市场细分是指根据消费者购买行为的差异性把一个总体市场划分成若干个具有共同特征的子市场的过程。因此,分属于同一细分市场的消费者,他们的需要和欲望极为相似;分属于不同细分市场的消费者对同一产品的需要和欲望存在着明显的差别。 相似文献
