To reduce the high incidence of poverty in rural households, agricultural modernization using innovations has been pursued by governments and actors in the agricultural innovation system (AIS). This study analyzed how agricultural innovations and farmer-actor interactions in the AIS contribute to poverty outcomes among agricultural households in Ghana. Data used was the Ghana socio-economic panel survey data with 891 and 2595 observations for cocoa and maize households, respectively. The multinomial endogenous treatment effect model with instrumental variables was employed for the analysis. Adopting digital technologies in combination with other innovations, and having stronger farmer-actor interactions in the innovation system were associated with non-poor outcome in maize-growing households, who were poorer compared to cocoa-growing households. Innovations that consistently increased food security in both crop systems were associated with non-poor outcomes. The findings of the study highlight the need for governments and stakeholders to prioritize agricultural digitalization, encourage the adoption of multiple innovations and focus on food security-improving interventions as strategies to addressing rural poverty reduction.
为降低农村家庭的高贫困发生率，政府和农业创新系统（AIS）中的行为主体一直在推行利用创新手段实现农业现代化。本研究分析了农业创新以及AIS中农民与行为主体之间的互动如何影响加纳农业家庭的贫困状况。所用数据为加纳社会经济面板调查数据，分别有891个可可种植户观测值和2595个玉米种植户观测值。分析采用了带有工具变量的多项内生处理效应模型。在玉米种植户中，采用数字技术并结合其他创新，以及在创新系统中与行为主体有更强的互动，与非贫困结果相关，而玉米种植户比可可种植户更贫困。在两种作物系统中持续提高粮食安全的创新与非贫困结果相关。该研究结果凸显了政府和利益相关者需要优先考虑农业数字化，鼓励采用多种创新，并将重点放在改善粮食安全的干预措施上，以此作为减少农村贫困的战略。
