中文摘要：

通过构建全面的软件和信息技术服务业发展水平的评价指标体系,采用因子分析法测算2006—2014年全国31个省域（除港澳台外）的软件和信息技术服务业发展水平指数,利用Kernel密度估计和GIS分析其时空演变。研究结果表明：我国软件和信息技术服务业发展水平总体上呈现稳步提升趋势,高水平省份的发展速度快于低水平省份,但是整体发展水平仍以中低水平为主;高水平和较高水平区集中分布在东部沿海地区,中低水平区主要分布在西北、西南等内陆地区,且地域范围不断扩大;内部行业以信息技术服务业为主,年均增长率高于平均水平。

英文摘要：

By building the evaluation index system of software and information technology services and adopting factor analysis,this paper measures and calculates the development index of software and information technology service industry in 31 provinces in China（ excluding Hong Kong,Macao and Taiwan） from 2006 to 2014. Thereby it studies the temporal and spatial evolution using Kernel density estimation and GIS technology. The results shows that in terms of temporal evolution,the development of software and information technology service industry show a steady rise in which more developed provinces enjoy a faster growth than less developed provinces. However the overall development pace is set by the less developed provinces. In terms of spatial evolution,the provinces which enjoy higher level of development mainly locate on the eastern coast while those with lower level of development are mainly distributed in northwest,southwest and other inland regions with its geographical scope expanding. The internal industries,mostly information technology services,enjoy an annual growth rate higher than the average.
