This study employs microdata from the China Labor-force Dynamics Survey to investigate the influence of foreign language proficiency on the adoption of Internet technology within households. The results indicate that householders who are proficient in foreign languages are more likely to adopt Internet technology at home than those who lack such knowledge. The greater the foreign language proficiency of the householder, the greater the likelihood of Internet technology adoption. Further analyses indicate that the positive effect of foreign language proficiency on the Internet technology adoption of the household in China is more pronounced in male-headed households, in urban areas, and in eastern and central regions. This study also identifies three potential mechanisms by which foreign language proficiency influences household Internet technology adoption: the information effect, the trust effect, and the income effect. These findings contribute to the understanding of the role of language proficiency in technology adoption at the household level, offer new insights into the positive outcomes of foreign language education in China, and encourage measures to reduce digital inequality among households through language learning.
