本研究探討了軟體代碼活動與代碼適應性之間的縱向關係，使用系統 GMM 的動態面板數據方法進行分析。研究發現，代碼適應性對代碼活動具有持續的 負面影響，且這一影響隨時間呈現單調遞減的趨勢。此外，研究還證實了代碼 活動的滯後效應，以及時間和團隊固定效應在項目開發過程中對代碼活動的影 響。研究結果對於軟體開發中的項目管理策略和資源分配決策具有重要意義， 強調了維持代碼適應性的持續需求。

This study investigates the longitudinal relationship between software code activity and code adaptability, using a dynamic panel data approach with system GMM. The research findings indicate that code adaptability has a persistent negative impact on code activity, with this effect decreasing monotonically over time. Additionally, the study confirms the lagged effect of code activity and the influence of time and team fixed effects during the project development process. These findings have significant implications for project management strategies and resource allocation decisions in software development, emphasizing the ongoing need to maintain code adaptability.
