英文文献：Linkages between Market Participation and Productivity: Results from a Multi-Country Farm Household Sample-市场参与与生产力之间的联系:来自多国农户抽样的结果

英文文献摘要：
We build upon international trade literature to analyze the direction of causality between market participation and productivity. Cross-country household data from Tanzania, Vietnam and Guatemala are used in a 2SLS approach with market participation and productivity as endogenous variables. Results indicate that households with higher productivity tend to participate in agricultural markets regardless of market access factors. In contrast, having better market access does not necessarily lead to higher productivity. This finding suggests that investments in market access infrastructure provide minimal, if any, improvements in agricultural productivity; whereas programs targeted at enhancements in farm structure and capital have the potential to increase both productivity and market participation.
我们以国际贸易文献为基础来分析市场参与和生产力之间的因果关系的方向。来自坦桑尼亚、越南和危地马拉的跨国家庭数据在2SLS方法中使用，市场参与和生产率作为内生变量。结果表明，无论市场准入因素如何，生产率较高的农户都倾向于参与农产品市场。相反，拥有更好的市场准入并不一定会导致更高的生产力。这一发现表明，对市场准入基础设施的投资对农业生产率的改善微乎其微，如果有的话;而旨在改善农场结构和资本的项目则有可能提高生产率和市场参与度。
