摘要
借鉴粘滞摩擦学中阻尼系数概念,建立中国城乡数字鸿沟对城市化进程阻尼系数测度模型,运用非参数估计方法对阻尼系数进行估计。研究发现:阻尼系数逐点估计值围绕总体估计值0.07695在区间[0.06898,0.08799]内小幅波动,说明城乡数字鸿沟对城市化进程动力的耗损是其固有的一种能力;城乡数字鸿沟对科技进步动力的耗损远大于对经济发展动力的耗损,通过经济发展加快城市化进程更为"划算"。
On the ground of thoughts concerning resistance from adhesive tribology , a model for measuring the drag coeffi-cient of urbanization from urban-rural divide （ URDD） in China is built .And drag coefficient is computed by using non-para-metric methodology.The result shows that coefficients vary ranging from 0.06898 to 0.08799, around 0.07695 for the whole estimation, with a slight latitude of fluctuations , demonstrating that the ability of URDD cannibalizing urbanizing powers is inherent .This paper also finds that URDD damages scientific forces even more than economic ones .Therefore , it is more worthwhile that urbanization process is accelerated by power from economy growth .
