中文摘要：

文章利用空间自相关和半变异函数分析上海本土企业合作意愿的空间差异及成因。研究表明：上海本土企业的合作意愿程度均大于2（一般重要程度）,“与大学和科研机构”合作意愿的偏度要低于“与外资企业”合作；在空间格局上，上海本土企业的合作意愿具有显著的空间差异；其中合作意愿的热点区位于中心城区和近郊区，冷点区主要位于远郊区，因此这种差异主要表现为中心城区与远郊区的差异，即合作意愿的强度由城市中心向四周递减，这与外资企业合作的冷热点区分布规律较为吻合；半变异函数模型的主轴方向表明合作意愿的空间差异在东西方向上变化最为剧烈，且块金系数均大于基台系数，说明上海本土企业的合作意愿受到随机性因素影，向较大,即上海本土企业的合作意愿不仅受到政策、经济等结构性因素的影响，更多地受到予企业内部的企业文化、产业类型发展定位等随机因素的影响。

英文摘要：

The paper, applying the spatial autocorrelation and the semi variation function, analyzes the spatial differences of cooperation willingness of local enterprises and their causes in Shanghai. The study shows that ： The degree of cooperation will- ingness of local enterprises in Shanghai is more than 2 （general importance） , and the skewness of willingness to cooperate with ＂universities and scientific research institutions＂ is lower than that of ＂foreign enterprises＂; On the spatial pattern, the cooperation willingness of local enterprises in Shanghai has significant spatial differences, among them the hot spots of cooper- ation willingness are located in the central city and suburban areas, whereas the cold areas are mainly in the outer suburbs, this manifests mainly as the difference between the central city and the outer suburbs, which means the strength of coopera- tion willingness decreases from the city center to the periphery, it is similar to the distribution of cooperation willingness of for- eign enterprises ; The principal axis direction of the semi variation function model shows that the spatial difference of coopera- tion willingness is the most intense in the east-west direction, and the nugget coefficient is greater than the base coefficient, which indicates that the cooperation willingness of local enterprises is strongly influenced by random factors, namely the coop- eration willingness of local enterprises is not only influenced by structural factors such as policy, economy and so on, but also more influenced by corporate culture, industry type, development orientation and other random factors inside enterprises.
