Compared with developed nations, developing countries are more vulnerable to climate change and variability. In this study, a coping and adaptation strategies (CCCAs) index, data envelopment analysis (DEA), and fractional regression model (FRM) are used to explore the impact of farmers' CCCAs on technical efficiency (TE) among goat farmers in Ghana. Using survey data collected from goat farmers in the northern part of Ghana, the results reveal the following: first, most of the farmers were inefficient in their production. Thus, out of the 124 goat farmers, only 13 (10.5%), 3 (2.4%), and 4 (3.2%) were efficient under variable return to scale (VRS), constant returns to scale (CRS), and scale efficiency (SE), respectively. Second, regarding a quantitative relationship, CCCAs can help increase farmer' efficiency. Again CCCAs impact on female farmers' TE was profound than their counterparts. Finally, CCCAs have heterogeneous impacts on goat farmers in different groups. Our findings provide policy implications to improve CCCAs and enhance the goat farmers' TE.
与发达国家相比，发展中国家更容易受到气候变化和变异性的影响。在这项研究中，采用应对和适应策略（CCCAs）指数、数据包络分析（DEA）和分数回归模型（FRM）来探讨加纳山羊养殖户的 CCCAs 对其技术效率（TE）的影响。利用在加纳北部地区采集的山羊养殖户调查数据，结果表明：首先，大多数养殖户的生产效率低下。因此，在 124 位山羊养殖户中，仅有 13 位（10.5%）、3 位（2.4%）和 4 位（3.2%）分别在规模报酬可变（VRS）、规模报酬不变（CRS）和规模效率（SE）下有效。其次，在定量关系方面，CCCAs 可以帮助提高农民的效率。此外，CCCAs 对女性农民 TE 的影响比男性更为显著。最后，CCCAs 对不同群体的山羊养殖户产生了异质影响。我们的研究结果为改善 CCCAs 和提高山羊养殖户的 TE 提供了政策启示。
