摘要

目的发展中国家的农民习惯于回收和购买老品种和低产品种的种子,导致种子和品种更替率低。尼泊尔的种子公司已经开始举办贸易商会议来推广水稻新品种。本文旨在评估这种方法在推广水稻新品种方面的有效性。设计/方法/方法作者通过调查尼泊尔7个地区的238名农产品经销商来评估TM的有效性。作者使用二元logit模型研究了参与TM的决定因素,并使用工具变量法估计了TM对推广水稻品种销售的影响。研究结果表明,TM显著影响贸易商的知识,并增加了销售推广水稻新品种的概率。然而,TMs并没有显著提高推广水稻品种的整体销售额。研究局限性/含义该研究基于横断面数据;因此,无法解释未观察到的固定效应。该研究只发现了一个相关且有效的工具变量,因此无法进行任何外源性测试。创意/价值尼泊尔的种子公司自2019年开始进行TMs,以推广水稻新品种。然而,据作者所知,TMs的有用性以及这些事件在改变贸易商对国产水稻种子品种的态度或商业业绩(推广品种的年销售额)方面的影响尚未得到评估。因此,研究结果将有助于推广市场驱动的种子系统,提高种子替代率。

Can traders' meetings boost seed sales of new rice varieties and promote a market-driven seed system? Evidence from Nepal
PurposeFarmers in developing countries are used to recycling and purchasing seeds of old and low-yielding varieties, leading to low seed and varietal replacement rates. Seed companies in Nepal have started to conduct traders' meetings (TMs) to promote new rice varieties. This paper aims to assess the effectiveness of this approach in promoting new rice varieties.Design/methodology/approachThe authors assess the effectiveness of TMs by surveying 238 agrodealers from 7 districts of Nepal. The authors used the binary logit model to study the determinants of participation in TM and an instrumental variable approach to estimate the impact of TMs on sales of the promoted rice varieties.FindingsResults indicate that the TM significantly influences traders' knowledge and increases the probability of selling new rice varieties promoted. However, TMs did not significantly increase the overall sales of promoted rice varieties.Research limitations/implicationsThe study is based on cross-section data; thus, unobserved fixed effects could not be accounted for. The study finds only one relevant and valid instrumental variable and therefore could not conduct any exogeneity test.Originality/valueSeed companies in Nepal started to conduct TMs to promote new rice varieties since 2019. However, to the best of the authors’ knowledge, the usefulness of TMs and the impact of these events in changing traders' attitudes toward domestic rice seed varieties or in business performance (annual sales of the promoted varieties) have not been assessed. Therefore, the study findings will help to promote the market-driven seed system and increase the seed replacement rate.
