Food Competition in World Markets: Some Evidence from a Panel Data Analysis of Top Exporting Countries
利用1992-2012年主要食品出口国的面板数据，研究发现加工食品的价格弹性较低而收入弹性较高，且加工食品的价格弹性与平均单位价值呈反向关系，表明新兴和发达国家均可增加加工食品出口专业化，发达国家可通过提升质量应对竞争。
Abstract This paper investigates the relevance of relative prices and world income as determinants of food exports for the top trading countries in the period 1992–2012 using a panel data framework. We find that price elasticities generally take lower values for processed goods, and the opposite holds for income elasticities. Processed goods are also characterised by an inverse relationship between price elasticities and average unit values. The analysis suggests that both emerging and advanced countries can be expected to increase their export specialisation in processed goods. Furthermore, developed economies can face fierce competition from emerging countries by enhancing the quality content of their processed good exports.
