摘　　要：采用我国283个地级市2003—2015年的面板数据,使用改进的引力模型测算了各省科技与经济联系的强度,考察了科技联系强度与经济联系强度之间的关系。结果显示:①各省科技联系强度、经济联系强度均在时间趋势上呈阶段性波动,两者未呈现明显的区域一致性;区域空间联系水平存在明显的空间分异特征,东部地区科技与经济联系强度均领先于中西部地区,且随时间推移地区间差距进一步拉大。②在考察期内,经济联系强度与科技联系强度之间呈"U"型关系,我国多数省份均处于"U"型曲线下降阶段;跨过拐点后,经济联系强度与科技联系强度正相关。③对外开放水平、科技投入水平对科技联系强度具有促进作用,产业结构、科技产出水平对科技联系强度具有抑制作用。Based on the panel data of 283 cities in China from 2003 to 2015,this paper adopted improved gravity model to calculate the scientific & technological linkage intensity and economic linkage intensity,and examined the relationship between them.The results showed that:①Scientific & technological linkage intensity and economic linkage intensity showed stage fluctuations in time trends.However,both of them didn't have evident region consistency.Regional spatial linkage intensity had evident differences.The eastern region was ahead of central and western regions in both scientific & technological linkage intensity and economic linkage intensity,regional disparities were widening with time.②The research showed that there existed U-shaped relationship between scientific & technological linkage intensity and economic linkage intensity.Most of the provinces in China were in the falling stage of the U-curve.There was positive correlation between scientific & technological linkage intensity and economic linkage intensity.③The level of opening up and the level of scientific & technological input had the positive influence on the scientific & technological linkage intensity,while the industrial structure and the level of scientific & technological output had the negative impact on the scientific & technological linkage intensity.

关 键 词：空间联系强度 科技联系 经济联系 引力模型 “U”型关系
