本文針對1996〜2010年珠三角與長三角區域的25個地級市層級以上之城 市，除了應用共同邊界（Metafrontier)模型考量區域間之差異，並在模型中内生 化環境變數對於技術無效率之影響，實證結果顯示，珠三角對外開放較早，其制 度上比長三角較具優勢，珠三角為中國大陸制度創新之發源地，但隨著政策逐漸 轉向長三角之際，珠三角經濟發展有逐漸勢微；此外，「十五計劃」實施，除提 升區域的效率及技術水準外，亦持續增強「十一五規劃」區域經濟協調發展之效 益。

This thesis aims at studying 25 cities which are at least prefecture-level cities in the Pearl River Delta and the Yangtze River Delta from 1996 to 2010, applying metafrontier model to consider the differences among these regions. Besides, in this model, we also exclude the impact of environmental variables from technical inefficiencies; hence, we can reasonably evaluate technical efficiency of regional economies. According to the experiment, the Pearl River Delta opens to the outside world earlier, and its concept and system are more advantageous than those of the Yangtze River Delta. Moreover, the Pearl River Delta serves as the birthplace of China’s system innovation; however, as policies turn the direction to the Yangtze River Delta step by step, the economic development of the Pearl River Delta goes downhill. Besides, the political implementation of "Tenth Five-Year Plan" in China offers great benefit to technical efficiency and technical standard of both the Pearl River Delta and the Yangtze River Delta in the “Eleventh Five-Year Plan.”
