In economics, an aggregate is a summary measure. It replaces a vector that is composed of many real numbers by a single real number, or a scalar. Consequently, there occur various problems that are inherent in the formulations that use aggregated variables. The aggregation problem is the difficult problem of finding a valid way to treat an empirical or theoretical aggregate as if it reacted like a less-aggregated measure, say, about behavior of an in… Webb聚合器理论Ben Thompson认为,ChatGPT是一种 Aggregator。Aggregation Theory是Ben Thompson提出的一种理论,在互联网产业界很有影响力。该理论认为,如果一家公司具备下面三个特征,那么就是聚合器,缺一不可: …
