Agricultural exports and economic growth in less developed countries
基于62个欠发达国家1974-1995年的面板数据，构建双经济模型分析农业出口对经济增长的贡献，发现农业出口与非农业出口的投资效应无显著差异，但非出口部门生产率比出口部门低30%以上。
Abstract This article examines the contribution of agricultural exports to economic growth in less developed countries (LDCs). A sources‐of‐growth equation is developed from a dual economy model where agricultural and nonagricultural sectors are both divided into export and nonexport subsectors. This is then estimated using panel data for 62 LDCs for 1974–1995. Results provide evidence that there are significant structural differences in economic growth between low, lower‐middle, and upper‐income LDCs. Investment in the agricultural export subsector has a statistically identical impact on economic growth as investment in the nonagricultural export subsector. The marginal productivities in nonexport subsectors are over 30% lower than those in respective export subsectors. From a policy perspective, the results suggest that export‐promotion policies should be balanced.
