摘要
区域经济发展差异研究是制定经济发展政策和战略的重要依据.基于2017年浙江省73个县域的16个经济指标,综合运用主成分分析与探索性空间数据分析方法,对浙江省县域经济发展水平及空间分异特征进行了分析,并从不同尺度运用地理探测器对影响县域经济发展水平差异的因素进行了分类探测.结果表明:1)在发展水平上,2017年浙江省县域经济发展水平总体较高,但浙东北与浙西南县域经济发展的区域差异显著.2)在空间分异上,浙江省经济实力相近的县域在空间分布上趋于集聚,核心区域位于杭州主城区—嘉兴市区、宁波主城区,在此基础上形成了四大发展区;发展水平较高的县域集中于浙东北地区,尤其是在杭州湾地区,浙西北山地地区县域发展水平较低.3)在影响因素上,经济规模对省域层面差异具有主导性作用;而浙东北与浙西南地区内部差异分别受经济规模与经济效益的影响,其中第三产业发展水平影响力显著;"高-高"(HH)类型与"低-低"(LL)类型县域内部差异分别受生产总值与工业总产值的影响.
The study of differences in regional economic development had been an important basis for formulating economic development policies and strategies.Based on 16 economic indicators of 73 counties in Zhejiang province in 2017,the principal component analysis and exploratory spatial data analysis method were used to analyze the economic development level and spatial differentiation characteristics of the county in Zhejiang province.The geographical detector from different scales was used to classify and detect the factors affecting the difference of county economic development level.The results showed that:1)At the level of development,the level of county economic development in Zhejiang Province was generally high in 2017,but the regional economic development between Northeastern Zhejiang and Southwestern Zhejiang differed significantly.2)In terms of spatial differentiation,the county areas with similar economic strength tended to gather in spatial distribution.The core area located in the main urban area of Hangzhou main-Jiaxing City and Ningbo main city,and on this basis,the whole province formed four development zones.The county with a high level of economic development was concentrated in the Northeastern Zhejiang,especially in the Hangzhou Bay area,while the county with a low level of development was concentrated in the Northwestern Zhejiang.3)In terms of influencing factors,the economic scale played a leading role in the provincial level.From the regional scale,the economic development differences of the Northeastern Zhejiang and the Southwestern Zhejiang were mainly affected by economic scale and economic benefits.From the spatial auto-correlation scale,the differences of the"high-high"(HH)type and the"low-low"(LL)type of county economic development were mainly affected by the GDP and industrial output value respectively.
