本論文は、中国の287都市のパネルデータを用いて、ブロードバンド中国政策がCO2排出強度に与える影響を差の差法で検証した。結果、パイロット都市では非パイロット都市に比べて排出強度が5.01%低下し、その効果はグリーン技術革新の促進とエネルギー消費強度の低減を通じてもたらされる。大規模・高開発地域で効果が顕著であり、途上国への示唆も提供する。
English
Using panel data from 287 Chinese cities, this study employs a difference-in-differences approach to show that the Broadband China policy significantly reduces CO2 emission intensity by 5.01% in pilot cities. The effect operates through promoting green technological innovation and reducing energy consumption intensity, with stronger impacts in larger and more developed regions. The findings offer empirical support for developing countries pursuing emission reduction through digitalization.

📄 Abstract（原文）
With accelerating global warming, reducing carbon emissions has emerged as a core task of global climate governance. In this process, digital infrastructure acts as a crucial catalyst for achieving sustainability goals. Drawing on a panel dataset covering 287 Chinese prefecture-level cities between 2010 and 2023, this paper examines how Broadband China policy influences carbon dioxide (CO2) emission intensity via a difference-in-differences approach. The outcomes show that Broadband China policy significantly reduces CO2 emission intensity, with pilot cities exhibiting a 5.01% decrease relative to non-pilot cities. This effect operates primarily through promoting green technological innovation and reducing energy consumption intensity. The reduction is more pronounced in large-scale and high developed regions, whereas the effect remains limited in small-scale and less developed regions. This study contributes to the literature by using carbon emission intensity, a structural indicator that better reflects the efficiency of low-carbon transition, to examine the digital economy and environmental governance. It further provides empirical support for other developing countries seeking to advance emission reduction through digitalization.
