摘要:

目的 文章在构建农产品品牌提高农业竞争力理论模型的基础上，剖析农产品品牌对农业竞争力的作用机理。方法 运用面板门槛模型和分位数回归模型，利用2011—2019年县域数据，将农产品地理标志的保护范围纳入到农产品品牌的测算中，实证检验了农产品品牌对农业竞争力的影响及作用机制。结果 （1）农产品品牌的提升能有效提高农业竞争力水平，川南经济区的农产品品牌对农业竞争力促进效果显著，而成都平原经济区和川东北经济区不能有效促进农业竞争力水平；（2）农产品品牌与农业竞争力之间存在经济发展和城镇化门槛效应，经济发展水平为门槛变量时，农产品品牌与农业竞争力之间呈现非线性增长，城镇化水平为门槛变量时，农产品品牌与农业竞争力之间呈现正“U”形关系；（3）在低分位点上，农产品品牌对农业竞争力呈现显著的正向影响，在高分位点上，农产品品牌对农业竞争力的影响不显著。结论 因地制策，充分发挥农产品品牌对农业竞争力的促进作用；量体裁衣，创新农产品品牌与经济发展和城镇化的协同发展机制；因势制导，推动农产品品牌从政策化迈入市场化。

Abstract:

Based on the theoretical model of agricultural brand enhancing agricultural competitiveness, this study analyzes the effect mechanism of agricultural brand on agricultural competitiveness. Based on the county data from 2011 to 2019, and the protection scope of geographical indications of agricultural products was included in the calculation of agricultural products brands for the first time, the panel threshold model and quantile regression model was used to empirically examine the impact of agricultural product brands on agricultural competitiveness and its mechanism. The results were listed as follows. (1) The promotion of agricultural product brand effectively improved the level of agricultural competitiveness. The agricultural product brand in south Sichuan economic zone had a significant promotion effect on agricultural competitiveness, but the Chengdu Plain economic zone and northeast Sichuan economic zone could not effectively promote the level of agricultural competitiveness. (2) There was a threshold effect of economic development and urbanization between agricultural brand and agricultural competitiveness. When the level of economic development was the threshold variable, the relationship between agricultural brand and agricultural competitiveness presented a nonlinear growth, and when the level of urbanization was the threshold variable, the relationship between agricultural brand and agricultural competitiveness presented a positive "U" shape. (3) At the low score loci, agricultural brand had a significant positive effect on agricultural competitiveness, while at the high score loci, agricultural brand had no significant effect on agricultural competitiveness. Therefore, it should make policies according to local conditions, give full play to the role of agricultural product brands in promoting agricultural competitiveness, and innovate the coordinated development mechanism between agricultural products brand and economic development and urbanization according to the circumstances, then promote agricultural products brand from the policy into the market due to potential guidance.
