Manuel Castells 在『THE RISE OF THE NETWORK SOCIETY－網路社會之崛起』一書中提出：
社會並非是為了適應於特殊的社會結構模型，才成為資訊化社會；而是透過資訊技術之發展與擴散，同時完成運用資訊技術所需之先決條件（人力資源與通訊基礎建設），使社會環繞著知識生產力最大化的原則來組組織其生產系統，而成為資訊化社會。
他試圖在先進資本主義國家 G7 在1920 與1990 年間就業與職業結構之歷史演變，檢視先進國家從後工業狀態下到資訊化社會勞動與就業轉型之共通性與差異性。不過在統計上因為各國時間序與資料分類的不一致與其他限制關係，因此本文將試圖以此方式來檢視台灣地區的勞動轉型資料對於由後工業狀態（postindustrialism）進入到資訊化狀態（informationalism）之間的探索。

Manuel Castells bring up idea in his THE RISE OF THE NETWORK SOCIETY：
In this perspective, societies will be informational, not because they fit into a particular model of social structure, but because they organize their production system around the principles of maximizing knowledged-based productivity through the development and diffusion of information technologies, and by fulfilling the prerequisites for their utilization (primary human resources and communications infrastructure.)
By tracing the historical development between occupational structure and employment condition from 1920 to 1990 among G7 advanced capitalist countries, he examined the consistency and difference in the transitional process of labor and employment situations from post-industrial conditions to informational society among those countries. By using Taiwanese data, the author in this paper tries to apply the same method in order to investigate the transitional process from postindustrialism into informationalism in Taiwanese society.
