黄河流域市际技术转移网络的时空特征

基于2010和2018年专利交易数据,融合GIS空间分析、空间自相关、社会网络分析方法,对黄河流域市际技术转移的空间分布格局及社会网络结构特征进行研究。结果表明:①黄河流域市际技术转移强度空间极化现象显著,高值区主要分布在山东、河南等省区,低值区主要分布于甘肃、青海、内蒙古、宁夏等西部省区;②黄河流域技术转移活动的空间集聚特征明显,技术转入空间集聚格局与技术转出空间集聚格局具有相似性,高高集聚区主要位于四川德阳与山东东部一些地市,低低集聚区主要位于青海、四川、甘肃、内蒙古等省市;③区域内部视角下,成都、西安、郑州等省会城市是内部技术转移网络的核心城市,核心-边缘结构凸显,内部整体网络密度较外部小;④区域内部技术转移地理邻近性特点明显,技术转移以向邻近城市与城市内部转移为主,且城市内技术转移占技术转移总量的比重较大;⑤外部视角下,2010-2018年无论是黄河流域对区域外技术转移,还是区域外对黄河流域技术转移,技术转移的数量和强度都明显增大,济南、青岛、西安、郑州、成都向区域外技术转移中占据重要地位,而北京、深圳、广州、上海是外部向黄河流域技术转移的重要节点。

Spatiotemporal Characteristics of Intercity Technology Transfer Network in the Yellow River Basin

Based on the patent transaction data in 2010 and 2018,the spatial distribution pattern and social network structure characteristics of inter city technology transfer in the Yellow River Basin are studied by integrating GIS spatial analysis,spatial autocorrelation and social network analysis methods.The results show that:1)The spatial polarization of inter city technology transfer intensity in the Yellow River Basin is significant.The high value areas are mainly distributed in Shandong,Henan and other provinces,while the low value areas are mainly distributed in Gansu,Qinghai,Inner Mongolia,Ningxia and other western provinces;2)The spatial agglomeration characteristics of technology transfer activities in the Yellow River Basin are obvious.The spatial agglomeration patterns of technology transfer in and technology transfer out are similar.High and high agglomeration areas are mainly located in Deyang of Sichuan Province and some cities in the east of Shandong Province,while low and low agglomeration areas are mainly located in Qinghai,Sichuan,Gansu,Inner Mongolia and other provinces and cities;3)From the perspective of regional interior,Chengdu,Xi’an,Zhengzhou and other provincial capitals are the core cities of the internal technology transfer network,with prominent core edge structure and less internal overall network density than the external ones;4)The geographical proximity of technology transfer within the region is obvious.Technology transfer is mainly to the neighboring cities and cities,and the proportion of technology transfer within the cities is large in the total amount of technology transfer;5)External perspective,both the Yellow River Basin from 2010 to 2018 for technology transfer,outside the territory or outside the area of the Yellow River Basin technology transfer,technology transfer and the number of strength are increased obviously,Jinan,Qingdao,Xi’an,Zhengzhou,Chengdu to occupy the important position in the technology transfer outside the territory,and Beijing,Shenzhen,Guangzhou,Shanghai is one of the important node external to technology transfer in the Yellow River.
