開放原始碼的快速發展吸引了許多人的參與，隨著個別開放原始碼專案貢獻人數的增加，對軟體品質究竟有何影響，是一個值得探討的議題。本研究由目前比較知名的開放原始碼平台 GitHub中，抽選中型的Java專案為研究對象，探討貢獻人數與品質特性之間的關係。由於品質特性僅為抽象之概念，故本研究採用 C&K 度量指標來進行評估。初步結果顯示：貢獻者人數與 RFC、CBO、DIT三項指標之間有顯著關係；就品質特性而言，隨著貢獻者人數的增加，會提升專案的複雜度，增加其錯誤率，使得維護較為困難，並降低程式碼的重用性。

As more people are contributing to open-source projects, it becomes worthy to investigate the relationship between the number of contributors and the quality characteristics of open-source projects. This study conducts such an investigation based on mid-size Java projects extracted from GitHub, a renowned hosting service for open-source projects. Due to the abstractness of quality characteristics, the evaluation is actually performed with Chidamber & Kemerer object-oriented metrics. Preliminary results show that the number of contributors is significantly related with RFC, CBO, and DIT. In terms of quality characteristics, as the number of contributors increases, complexity and fault-proneness also increase while maintainability and reuse fall.
