摘要:

食品认证体系建设对产品出口质量升级至关重要,而这一点在以往的研究中往往被忽视。本文将行业层面绿色食品认证数据与HS6分位农食产品出口数据进行匹配,实证分析了中国国内绿色食品认证对农食产品出口质量的影响。我们发现,绿色食品认证显著提升了中国农食产品的出口质量。基于工具变量的2SLS估计和一系列稳健性检验证实了基准结论的有效性和稳健性。拓展性分析发现,绿色食品认证通过提高农业生产效率和提升品牌溢价优势促进产品出口质量提升。异质性分析结果表明,分地区来看,绿色食品认证对出口到发达地区、进口监管高水平地区的农食产品的出口质量的提升效果更大;分产品来看,对初级农食产品、容易遭受非关税壁垒的农食产品的出口质量的提升效应更明显。上述研究结论对指导中国农食系统质量认证体系建设及农食产品贸易转型升级具有重要启示。

Abstract:

The construction of a food certification system plays a vital role in upgrading export quality, which previous studies have largely overlooked.  We match China’s industry-level data of Green Food Certification with its HS6-digit export data of agri-food products to quantify the impact of Green Food Certification on export quality.  We identify the significant and positive effect of Green Food Certification on export quality.  The 2SLS estimation based on instrumental variables and a range of robustness checks confirm the validity and robustness of the benchmark conclusions.  Further analysis discloses that Green Food Certification improves export quality by raising agricultural production efficiency and brand premiums.  Heterogeneity analysis shows that the effect of Green Food Certification varies across regions, notably improving the quality of agri-food products exported to developed regions and regions with high levels of import supervision.  Furthermore, among various product types, Green Food Certification significantly improves the export quality of primary products and products vulnerable to non-tariff measures.  The above findings could guide the future development of agri-food quality certification systems, potentially leading to a transformation and promotion of the agri-food trade.
