本研究運用AIDS需求模型來研究中國大陸城鎮地區的食品需求。資料使用1992年至2001年中國大陸29個城鎮地區的家計單位資料，並且選取9種主要的食品(包括糧食、油脂、豬肉、家禽、水產品、蛋、奶及奶製品、蔬菜與水果)來進行分析。在實證分析上，本研究所使用的追蹤資料方法中的固定效果模型，並且分成橫斷面資料、時間序列資料以及兩者兼具的效果。結果顯示，三種固定效果模型都為我們的分析提供更多的訊息；經由計算出的自身價彈性介於0與-1之間，表示這9種食物皆符合需求法則，且對價格的變動較不具彈性；而支出彈性皆為正值，表示這些食物都是正常財，當支出增加1％時，這9種食物的消費量都會增加，而且對家禽、水產品、奶及奶製品與水果消費量增加的幅度更是大於1％。

This study estimates the AIDS model by employing the urban China household’s food consumption data form 1992 to 2001. Nine food groups are selected in this study, including grain, oil, pork, poultry, aquatic products, eggs, milk and dairy products, vegetables, and fruits. The methodological approach followed in the study is the fixed effect model of panel data. We divide the fixed effect into three parts, including cross-section data, time series data, and both of them. The empirical results show that three types of fixed effect model actually give us more information to analysis. The own-price elasticities of all food are from -1 to 0. This indicates that all foods are consistent with the law of demand and less elastic when food price change. The expenditure elasticities are all positive implying the consumption of these nine foods will increase when the expenditure of people in urban China increases, especially for poultry, aquatic products, milk and dairy products, and fruits.
