偏离份额分析在县域经济结构空间差异研究中的应用--以江苏省宜兴市为例

对宜兴市各镇三次产业数据进行偏离份额分析处理,提取出各镇三次产业的竞争分量和结构分量,并对两分量的镇间组合与宜兴市交通干线的关系进行分析。结果表明,该市产业发展不均衡,第一产业总体处于衰退状态,第二产业发展迅猛,第三产业增长缓慢。竞争力分量和产业结构分量空间差异明显,环保科技园、屺亭镇和官林镇两分量都处于优势,而两分量在交通区位差的8个镇都表现为劣势,与各镇交通状况相关性强。

Application of Shift Share Analysis in Spatial Difference Research on County Economic Structure

Shift share analysis method was an effective method for quantitatively analyzing the status of industrial structure in regional economics.Industrial data of Yixing city was processed by using this method.And competitive component and industrial structure component of each town were extracted.Relationship between combination on town level of the two components and the traffic in Yixing city was analyzed.Result showed that industrial development in Yixing city was unbalanced.The first industry withered and the second industry grew fast.However,the third industry increased slowly.There were significant difference between competitive component and industrial structure component.The two components in Huankeyuan town,Qiting town and Guanlin town had superiority.But the two components in eight towns were in inferior position,which had obvious correlation with traffic system.All the research result could offer references for industrial structure adjustment in Yixing city.
