本文件描述了乌干达木炭价值链的特点，重点是该国中西部三个地区的生产和贸易。数据来自2008年对407个木炭价值链参与者进行的调查。调查包括171个木炭生产家庭和236个非生产者参与者，包括代理商、贸易商、运输商和零售商。线性回归模型被用来研究价值链上的整体利润和沿着单位销售利润，并检验关于地点、人力和社会资本以及资产所有权对观察到的经济回报和活动规模的重要性的几个假设。有证据表明，参与木炭价值链的总体回报最大的是贸易商。收益与活动规模呈正相关。控制参与者在木炭贸易中的作用，他或她的特点，和可用的资产，我们发现很少或没有证据表明地区之间的经济回报差异，尽管广泛流行的意见，在木炭的供应差异。相对于主要市场的生产地点以及具体地点的监测和执行水平与观察到的结果没有很大的相关性。
SUMMARY This paper characterizes the charcoal value chain in Uganda, focusing on production and trade in three districts in the west central region of the country. Data come from surveys of 407 charcoal value chain participants undertaken in 2008. The surveys included 171 charcoal-producing households and 236 non-producer participants including agents, traders, transporters and retailers. Linear regression models are used to study overall profits and per-unit marketing margins along the value chain and to test several hypotheses regarding the importance of location, human and social capital, and asset ownership on observed economic returns and scale of activity. Evidence suggests the greatest overall returns to participation in the charcoal value chain are found among traders. Returns are positively correlated with the scale of activity. Controlling for a participant's role in the charcoal trade, his or her characteristics, and available assets, we find little or no evidence of differences in economic returns among districts, despite widespread popular views of differences in available supply of charcoal. Location of production relative to major markets, and location-specific levels of monitoring and enforcement are not strongly correlated with observed outcomes.
