流动人口迁居行为涉及宏观、中观、微观三种空间尺度。在三种空间尺度下,流动人口的迁居行为均表现出近距离迁居的特点,但宏观尺度上还受到流出地与目的地经济发展水平差的影响。中观、微观尺度下的迁居原因比较相似,工作地点变动是最主要的原因,为了靠近亲戚朋友而迁居的人比例均不高。据此,在劳动力资源竞争日趋激烈的情况下,各流入地应密切关注首选本市的人群比例变化,该比例显示出城市人力资源竞争力的强弱。
The mobility of floating population can be analyzed with macro, median and micro scales. While short -distance floating is measured as an important characteristic by all the three scales, the developmental gap between their origin and destination is another one according to macro - scale. Both median and micro scales show similar causes for the mobility, with the change of working place as the most important one, while the preference to be close to relatives and friends as relatively a minor one. The paper thus points out when competition for labor force is more and more severe, the destination city should watch out the ratio change of inflowing people who take the city as their first choice, for the ratio stands as the symbol of a city's competitive capacity.
