基于灰色系统理论的我国技术梯度研究

Study on Technology Gradient of China Based on Grey System Theory

通过标准化原始数据和完善指标体系,对现有的基于灰色系统理论的技术梯度判断模型进行优化,在此基础上对我国的技术梯度进行定量分析,并首次绘出了我国的技术梯度图谱。研究结果表明:我国技术梯度的区域分布基本呈现出"从东到西梯度逐渐降低,中部地区实现崛起,局部地区高、中、低梯度交叉分布"的态势,同时沿海地区的"极化效应"和"回程效应"非常明显。

This paper optimizes the technology gradient model based on grey system theory by standardizing original data and improving indicator system. Using the optimized model, this paper analyzes the technology gradient of China from quantitative perspective and draws the map of Chinese technology gradient for the first time. Research results show as fol- lows： the regional distribution of Chinese technology gradient is that ＂the gradient drops down gradually from east to west; central China rises; in some place, the high, middle and low gradient are cross- distributed＂; at the same time, the polarization effect and return effect of Chinese coastal area are very obvious.
