本論文旨在瞭解鹿港老街遊客之懷舊情感，地方依附與負責任環境行為的現況，進而建構並驗證「懷舊情感，地方依附與負責任環境行為關係模式」，以探討懷舊情感與地方依附對負責任環境行為之影響，最後探究地方依附在懷舊情感與負責任環境行為間扮演的中介角色。本研究透過便利抽樣法進行問卷調查，共計回收403份有效樣本，以結構方程式進行分析後，結果顯示：懷舊情感會正向且顯著地影響地方依附，懷舊情感與地方依附亦會分別正向且顯著地影響負責任環境行為；此外，地方依附在懷舊情感與負責任環境行為間扮演部分中介之角色。根據上述結果，作者提出實務上之管理意涵與建議，供相關單位參考。

This study examines the causal relationships among nostalgia, place attachment and environmentally responsible behavior (ERB), as well as the mediating effect of place attachment. 403 tourists were surveyed who had visited Lukang historical site, Changhua County, Taiwan. Structural Equation Modeling was used to determine the relationships among the variables and the mediating effects. Results show that place attachment which tourists have for Lukang are positively associated with stronger ERB; the extent of nostalgia of Lukang as perceived by tourists is positively and significantly influence ERB. A higher level of tourists' nostalgia in regard to Lukang is also associated with stronger place attachment; place attachment was found to exert a significant effect in mediating the relationship between nostalgia and ERB. In other words, when tourists are nostalgic toward Lukang area, they are more likely to demonstrate ERB. Management implications and recommendations for the administrators of Lukang historical site are subsequently provided.
