基于SEM-PLS模型的区域信息技术服务业发展程度对行业绩效的影响

SEM-PLS Model-based Analysis on Impacts of Regional IT Service Development on Industry Performance

根据结构方程模型法(SEM)的基本原理,将区位商纳入评价指标体系,构建我国区域信息技术服务业发展程度对行业绩效的影响评价模型。运用偏最小二乘估计法(PLS)对模型进行拟合与检验,并对我国31个省级行政单位进行实证研究,探讨区域间信息技术服务行业绩效的差异,对区域信息技术服务业的科学发展有一定的指导意义。

According to the basic principle of Structural Equation Modeling （SEM）, this paper introduces location quotient （LQ） in- to the evaluation index system, builds an evaluation model for the influence of regional IT service development on industry perfor- mance. It uses partial least square （PLS） to fit and test the model, makes an empirical study on 31 provincial-level units in China, dis- cusses differences of IT service industry performance among regions. It has a certain guiding significance for scientific development of rezional IT service.
