網絡共同犯罪（狹義），是指數個行為人共同通過網絡而實施的針對電腦網 絡系統及數據資料的共同故意犯罪行為。鑒於網絡共同犯罪具有網絡化特徵， 致使其在認定和處理上都與傳統共同犯罪有著較大的差別，尤其是在犯罪行為 人的主觀及犯罪行為的客觀方面。在主觀方面，行為人之間的犯意聯絡往往是 通過網絡空間形成，具有隱蔽性、模糊性及不確定性等特點；在客觀方面，犯 罪行為必須利用網絡空間實施，具有技術性、隱蔽性等特點。同時，基於主客 觀方面的特點，致使網絡共同犯罪行為人中的正犯與從犯、法人網絡犯罪及聚 眾型網絡犯罪也相對於傳統共同犯罪表現出更為複雜之情況，成為刑法理論界 必須予以關注的重要課題。 基於此，本文重點圍繞網絡共同犯罪的定義、成立條件等進行分析，並在 參考相關理論和學說及其他國家和地區的相關刑法規定和做法的基礎上，總結 網絡共同犯罪之認定，以及網絡共同犯罪與法人網絡犯罪之區別，並進而評析 聚眾型網絡犯罪的問題及提出相關完善建議。 具體來說，本文主要分為以下四章： 第一章“網絡共同犯罪概述”。透過對網絡犯罪及共同犯罪的闡述及構成 要件的分析，帶出網絡共同犯罪的概念、特點和成因，以及總結網絡共同犯罪 和傳統共同犯罪的不同之處，從而為網絡共同犯罪之認定提供理論基礎。 第二章“網絡共同犯罪之認定”。包括網絡共同犯罪的主觀意圖、行為及 主體之認定，以冀釐清及確定網絡共同犯罪的成立要件。 第三章“網絡共同犯罪與法人網絡犯罪”。通過闡釋網絡共同犯罪和法人 網絡犯罪的區別，進一步分清網絡共同犯罪的含義及完善其認定的標準。 第四章“聚眾型網絡犯罪”。網絡聚眾性是網絡共同犯罪中最典型的特 點，通過對這種犯罪類型進行獨立分析、闡述其概念和特徵，以及相關立法的 現狀及局限性，總結聚眾型網絡犯罪在認定和制定相關法律規範方面應當注意 的問題。
