中国省域数字产业的经济效应研究

Economic Effects of Provincial Digital Industries in China

摘要

数字经济成为我国区域经济高质量发展的重要引擎，探讨中国省域数字产业的经济效应极为必要。本文立足省域视角，基于2017年中国省级社会核算矩阵，分别从数字产业的账户乘数效应与居民收入效应2个维度展开探讨。研究发现：1）从不同劳动力类型看，数字产业部门的单位投入对技术工人收入的影响程度均高于生产工人收入和农业劳动力收入的促进作用，表明数字经济发展更加有利于提高技术工人的相对收入；2）从各省份城乡差异看，北京、天津、上海、江苏、广东等东部省份数字产业单位投入会拉大城乡居民收入差距，而西藏、甘肃、青海、宁夏等西部地区省份该行业的单位投入或将缩小这些省份的城乡收入差距；3）从结构路径分解看，各省“通信设备、计算机和其他电子设备”主要影响“非金属矿物制品”“金属冶炼和压延加工品”等部门，然后传导至“非金属矿和其他矿采选产品”“金属矿采选产品”及“仪器仪表”等部门，而各省“信息传输、软件和信息技术服务”主要影响“通信设备、计算机和其他电子设备”等部门，然后传导至“煤炭采选产品”“金属冶炼和压延加工品”等部门。

Abstract

Digital economy has become the vital engine for China's regional quality economic development, which is necessary to explore the economic effects of China's provincial digital industries. This paper, according to China's 2017 provincial social counting matrix, studies the economic effects of provincial digital industries from account multiplier effect and residents' income effect of digital industries. Viewing from different labor categories, unit input of digital industries on technician's income in influence is higher than production labors' and farmers' income. From provincial differences, unit input of digital industries will enlarge the rural-urban residents' income gap in Beijing, Tianjin, Shanghai, Jiangsu and Guangdong, but on the contrast in Tibet, Gansu, Qinghai and Ningxia, most western China. Structural paths show that provincial “communication equipment, computers and other E devices” mainly impact “non-metallic mineral products”, “metallic smelting and rolling products” departments, and then transmitting to “non-metallic minerals and other mining and processing products”, “metallic mining and processing products”, and “equipment and meters” departments. Provincial “information transmission, software and information technology servicing” largely impact “communication equipment, computers and other E devices” departments, and then transmitting to “coal mining and processing products” and “metallic smelting and rolling products” departments.
