藍鼎元是清代頗具盛名的學者與地方官員。雖然正式擔任官職的時間並不長，官階更是不高，但雍正五年至七年（1727~29年）間任職廣東省普寧縣兼潮陽縣知縣時，不僅深得人民敬重而官聲卓著，更留下許多有關潮汕地區的描繪和資料。除了藍鼎元生平著作的整理外，透過這些資料的探索，我們不僅可以對清初潮汕地區的種種生活現象能夠有所體察，更可以一探明清地方官員在行政事務的管理與執行。 　　藍鼎元掌理普寧、潮陽二縣時，將經手之案例做一篩選整理，完成《鹿洲公案》一書。作者從《鹿洲公案》的具體事例中，輔以相關詩文著作及後人論述，嘗試著從地方行政中的錢糧、刑名、教化等項目來說明清初潮汕地區的社會現象、地方政府組織和行政事務的處理，進而分析一縣之長—知縣在地方行政上所擔負的職責與施政過程中的利弊與影響。
