基于产业关联的部门经济增长差异研究

为研究产业关联与区域经济增长的关系，在运用投入产出表分析各产业关联关系的基础上，对偏离份额模型进行改进，建立动态部门偏离份额模型，提出从产业间相互作用的视角研究经济增长的方法。该模型将经济增长分解为部门国家分量、部门结构分量和部门竞争力分量，从产业关联的视角有效地分析经济增长或衰退的原因。利用2007—2014年江苏省8类行业的数据进行实证分析，结果表明动态部门偏离份额模型对各行业和地区经济增长的分析是合理的，各行业受其他行业的影响程度具有动态变化并呈现不稳定特征。

On the sector difference of economic growth based on industrial correlation

A dynamic sector shift share model which is a revision of shift share model is put forward in order to study the correlation of industrial relationship and regional economic growth. This newly proposed model is based on the analysis of the relationship between different industries by the input and output table from a new perspective of the interactions between different sectors. The dynamic sectoral shift share model decomposes the change of total economy into three components, namely sectoral national effect, sectoral structural effect and sectoral regional shift effect. This model can effectively analyze the cause of economic growth or recession from the perspective of industrial correlation. The paper also makes an empirical analysis of the data of eight main industries in Jiangsu Province from 2007 to 2014. The results show that the model is reasonable when it is used to analyze the industries and regional economic growth. The influence of one industry from other industries is dynamic and instable.
