【内容提要】互联网接入和使用能否有效缩小健康不平等，在以往研究中尚未达成共识。本研究采用 2021 年中国综合社会调查（CGSS）数据，运用内生转换模型，从接入沟和使用沟两个维度分析互联网使用导致的健康数字鸿沟。研究发现，高社会经济地位群体有更大的可能性使用互联网，并利用互联网检索健康/医疗信息；互联网使用和检索行为提升了人们的自评健康水平。但是，随着互联网广泛普及和人们不断利用互联网获取健康服务，高社会经济地位群体在互联网使用过程中并未获益更多，不同社会经济地位群体间的健康不平等没有扩大，而是缩小了。互联网作为一种重要资源，对低社会经济地位群体具有更重要的健康促进价值。

Health Digital Divide:How Does the Internet Change Health Inequalities?

Abstract: The impact of internet access and usage on reducing health inequalities remains inconclusive in previous studies. This study uses data from the China General Social Survey (CGSS 2021) and applies an endogenous switching regression model to analyze the health digital divide from two dimensions: access and usage.The findings show that individuals with higher socioeconomic status (SES) are more likely to use the internet and search for health/medical information. Both internet usage and information searching enhance individuals’self-rated health. However,high-SES groups do not benefit more during internet usage than low-SES groups.The degree of health inequality between different SES groups is not exacerbated but rather reduced. As an important resource, the internet plays a more significant role in promoting health for low-SES groups.
