摘　　要：基于2005～2010年中国37个工业行业面板数据,对中国工业信息化水平与盈利能力的互动关系进行了实证考察.结果表明：我国工业信息化水平与盈利能力在长短期内均表现出显著的双向因果关系,且具有相互促进的累积循环效应,从而为“第四利润源”理论提供了实际证据.进一步研究发现,在“第四利润源”的驱使下,企业往往会更加注重自身信息化水平的提升,即存在一定的反哺效应;中国工业信息化水平与盈利能力的互动关系因行业差异而表现出显著的异质性特征.Based on the Chinese thirty seven industrial panel data from 2005 to 2010, the level of information on the Chi- nese industrial sector profitability and the interaction between the empirical investigations. The results showed that： Chinese industrial informatization level and profitability of the industry in the long term have shown a significant two-way causality, and has a mutually reinforcing effect of the cumulative circulation, so as the ＂fourth source of profit＂ theory provides empiri- cal evidence, in ＂the fourth source of profit＂ driven, companies also tend to pay more attention to improve their level of in- formation, that there is a certain nurturing effect; further study found that Chinese industrial informatization level and profit- ability of the industry due to the interaction between industry differences the exhibit significant heterogeneity.
