研究：美国 IT 投资与爱尔兰数据中心电力正在重构 Kitchin 周期

The Digital-Energy Recomposition of the Kitchin Cycle: Exploratory Evidence from U.S. IT and Irish Data-Centre Series (1995-2025)

导读

一项基于 1995Q1-2025Q4 季度数据的研究发现，美国 IT 投资与 GDP 的相关性在 2014Q3 出现显著断点，相关系数从 +0.45 降至 -0.12，比人工智能（AI，Artificial Intelligence）时代早约六年。

证据摘录

“Using quarterly FRED and CSO Ireland data over 1995Q1-2025Q4, we examine whether U.S.\ IT investment and Irish data-centre electricity are recomposing the Kitchin cycle around energy- and compute-backed assets.”
“Given the small AI-Era samples and the absence of a quarterly multinational-adjusted aggregate such as GNI*, all coefficients are exploratory”
“subject to these caveats, the U.S.\ Kitchin cycle is best dated to 2014Q3, and the Irish Energy-Data Nexus is dominated by multinational firm activity”
