英文文献摘要：
Since 2003, the NEPAD Comprehensive Africa Agriculture Development Programme (CAADP) has been endorsed by African Heads of State and Governments as a vision for the restoration of agricultural growth, food security, and rural development in Africa. The program aims at stimulating agriculture-led development that eliminates hunger and reduces poverty and food insecurity. As pointed out by Etro (2001), the creation of a union or adoption of a common agenda should move the equilibrium toward the first best solution whenever policies generate spillovers. This arises because the ability of a common agenda to reduce the scope of free-riding behavior among member countries. In addition, increasing world market integration leads to more externalities which call for policy coordination and supernational jurisdictions (Spolaore and Wacziarg, 2000). Using Spatial Durbin Model for panel data, the paper intends to investigate the presence of externalities in agricultural production within sub-Saharan African countries to validate the rationale for initiating CAADP. The model is estimated for the 1961-2006 period as well as sub-periods between 1961 and 2006. Over time, the results confirm the existence of positive and significant agricultural spillover. The findings suggest that the speed of convergence is faster when accounting for agricultural production spillover across countries.
自2003年以来，新伙伴关系非洲农业综合发展计划(CAADP)已得到非洲国家元首和政府首脑的认可，作为恢复非洲农业增长、粮食安全和农村发展的愿景。该项目旨在刺激以农业为主导的发展，消除饥饿、减少贫困和粮食不安全。正如Etro(2001)所指出的，当政策产生溢出效应时，联盟的创建或共同议程的采纳应该使均衡向第一个最佳解决方案倾斜。这是因为共同议程能够减少成员国之间搭便车行为的范围。此外，世界市场一体化程度的提高导致了更多的外部性，这需要政策协调和跨国管辖(Spolaore and Wacziarg, 2000)。利用空间Durbin模型的面板数据，本文打算调查外部性在撒哈拉以南非洲国家的农业生产的存在，以验证启动CAADP的基本原理。该模型是对1961-2006年以及1961-2006年的子期进行估计的。随着时间的推移，结果证实了农业溢出效应的存在。研究结果表明，考虑到各国之间的农业生产溢出效应，趋同的速度更快。
