本研究探討《客語為通行語實施辦法》與客語能力認證在客家文化重點發展區的實施成效、挑戰與未來展望。透過文獻分析與深度訪談，研究選取低、中、高客家人口比例地區進行比較，分析政策執行的差異及影響因素。結果顯示，將客語作為地方通行語的政策有助於提升其語言地位，並提高公務人員參與客語認證的動機。然而，初級認證級別未能完全滿足日常客語溝通需求，且實務應用仍面臨誘因不足與推廣力度不夠的挑戰。政策的實施成效亦受到地方客家人口比例、語言環境及機關首長支持態度等因素的顯著影響。 為提升政策執行效能，本研究建議應重視客語市場需求的創造，優化客語為通行語的評核標準，並強化中央與地方之間的跨部會合作與長期規劃。同時，應建立系統化的成功經驗分享與資源共享機制，以促進不同地區間政策的聯動與協調，從而提升整體政策效益。 ;This study examines the implementation effectiveness, challenges, and future prospects of the Hakka as a Local Common Language Implementation Measures and the Hakka Language Proficiency Certification in key Hakka cultural development areas. Through document analysis and in-depth interviews, the study compares regions with low, medium, and high Hakka population densities to analyze differences in policy execution and influencing factors. The findings indicate that the policy of adopting Hakka as a local common language helps enhance its status and increases the motivation of public servants to participate in Hakka certification. However, the elementary-level certification fails to fully meet the needs of daily Hakka communication, and its practical application continues to face challenges due to insufficient incentives and inadequate promotion efforts. The effectiveness of policy implementation is also significantly influenced by factors such as the proportion of the local Hakka population, the linguistic environment, and the level of support from institutional leaders. To improve policy execution, this study recommends focusing on creating demand for Hakka in the market, refining the evaluation standards for Hakka as a Local Common Language, and strengthening cross-ministerial collaboration and long-term planning between central and local governments. Additionally, establishing a systematic mechanism for sharing successful experiences and resources would facilitate policy coordination and interaction across different regions, thereby enhancing overall policy effectiveness.
