中国国防科技工业的空间协同现状分析

中国国防科技工业以十大军工集团为核心，十大军工集团及其下属企业的空间分布等状况基本反映了中国科技工业的总体特征。采用皮尔森相关性分析，从企业数量和投资规模两个角度，衡量同一空间单元中十大军工集团相互间的线性关联性程度。结果表明：中国核工业集团与其他军工企业的空间协同性最高，兵器类军工集团与其他国防科技工业的协同性最低；航空航天及船舶类军工集团与相关行业的协同性很高；兵器类军工集团则基本自成体系，与全国制造业及相关行业产业布局基本都不相关。研究成果可为后续深入研究国防科技工业的布局优化策略提供理论基础。

Status Analysis on the Space Collaboration of Chinese National Defense Science and Technology Industry

Chinese national defense science and technology industry is centered on the top ten military industry groups, and the spatial distribution of the top ten military industry groups and their subordinate enterprises basically reflects the overall characteristics of Chinese science and technology industry. From the perspective of the number of enterprises and the scale of investment, Pearson correlation is used to measure the degree of linear correlation between the number of enterprises or the scale of investment between the top ten military industrial groups in the same space unit.The results show that the space synergy between China National Nuclear Corporation and other military enterprises is the highest, and the coordination between the arms military industry group and other national defense technology industries is the lowest.Aerospace and shipbuilding military industrial groups are highly synergistic with related industries, while weapons military industrial groups are basically self-contained, and are basically irrelevant to the industrial layout of the national manufacturing industry and related industries.It provides a theoretical basis for the subsequent in-depth study of the layout optimization strategy of the national defense science and technology industry.
