摘　　要：在新经济地理学将空间要素纳入主流经济学的研究范畴后,空间数据统计分析方法也被引入经济学文献中。以地理邻近性为基本特征的集聚经济成为重要的研究对象并逐渐成为经济地理学与GIS交叉研究的领域。Ripley’s K函数属于空间点模式分析中基于距离的方法,也被称为多距离空间聚类分析,DO指数在其基础上发展而来,相比于K函数,DO指数更符合经济学中企业不完全随机分布的计算标准。本文根据2008年和2018年经济普查数据,以《中国经济普查年鉴》为参考标准,清洗数据后利用DO指数测度了京津冀协同发展战略提出前后制造业协同集聚的特征和动态演化过程。结果表明:①2008年和2018年分别有85.47%和82.53%的制造业产业对发生协同集聚,平均强度由0.030变为0.029,10年间协同集聚的基本格局保持稳定;但协同集聚强度高的TOP 20行业对明显向河北省扩散;②协同集聚发生的尺度范围扩大,2008年全部行业对协同集聚的显著尺度范围是25~68 km,2018年则是55 km以内和75~103 km。省市边界临界值约为75 km,京津冀协同发展战略提出后制造业跨省级行政区的合作更多,而TOP 20行业对的跨行政边界特征更加明显;③制造业协同集聚呈现“两极分化”特点,行业间协同集聚强度值高的更高,但中等强度协同集聚的行业对强度值变低。2018年第一个局部高值出现的尺度为54.5 km,小于2008年的68 km,但整体上显著尺度范围又大于2008年,协同集聚的行业对空间分布尺度范围小的更小,大的更大,在一定程度上验证了协同集聚存在循环累积因果效应。The statistical analysis methods of spatial data have also been introduced into economic literature after the new economic geography theory brought spatial elements into the research scope of mainstream economics.The agglomeration economy,with geographical proximity as its basic feature,has become an important research object and has gradually become the cross-research field of economic geography and GIS.The Ripley's K function belongs to the distance-based method in spatial point pattern analysis,also known as multi-distance spatial cluster analysis.The DO index develops on this basis.Compared with the K function,the DO index is more in line with the calculation standard of incomplete random distribution of enterprises in economics.In 2014,the coordinated development of the Beijing-Tianjin-Hebei region became a major national strategy.To verify the effectiveness of policy implementation,based on the economic census data of 2008 and 2018,we cleaned the data with the China Economic Census Yearbook as the reference standard.Then,we used the DO index to measure the characteristics and dynamic evolution process of manufacturing co-agglomeration before and after the coordinated development of the Beijing-Tianjin-Hebei region strategy was proposed.The results show that:(1)In 2008 and 2018,85.47%and 82.53%of manufacturing industry pairs respectively experienced co-agglomeration,with the average intensity changing from 0.030 to 0.029.The basic pattern of co-agglomeration remained stable over the past 10 years.However,the TOP 20 industry pairs with high co-agglomeration intensity value have shown the characteristics of obvious diffusion to Hebei Province.(2)The scale of co-agglomeration has expanded.In 2008,the significant scale of co-agglomeration for all industry pairs was 25-68 kilometers,while in 2018,it was within 55 kilometers and 75~103 kilometers.The average scale of co-agglomeration for the TOP 20 industry pairs increased from 80.91 kilometers to 125.15 kilometers.The critical value of the provincial and municipa
