Abstract

This study examines the impact of food quality certification on farms’ eco-efficiency in China, recognizing that the certification acts as a catalyst for encouraging more sustainable practices. The data was collected from 1855 vegetable growers in Shandong and Hebei provinces. Following a two-step approach, stochastic frontier analysis is applied to estimate eco-efficiency scores of smallholder farms, and a multinomial endogenous switching regression model is used to estimate the implication of certification schemes on eco-efficiency, while accounting for selectivity bias due to both observed and unobserved factors acting as a confounder. The empirical results suggest that hazard-free certification increases the eco-efficiency score for vegetable farms by 2.7%, followed by green certification by 4.6% and organic certification by 16.3%, respectively. Meanwhile, we find that the farmer’s certification adoption decision is significantly associated with farm size, farming experience, off-farm income, extension service, and social capital, which should be taken into account as policy recommendations to sustain and improve the positive effects of certification in regard to both economic and environmental aspects.

食品质量认证能提高生态效率吗?中国蔬菜生产的经验证据

本研究考察了食品质量认证对中国农场生态效率的影响，认识到认证是鼓励更多可持续实践的催化剂。数据来自山东和河北省的1855名蔬菜种植者。采用两步法，采用随机前沿分析估计小农生态效率得分，并采用多项内生转换回归模型估计认证方案对生态效率的影响，同时考虑由于观察和未观察因素作为混杂因素而产生的选择性偏差。实证结果表明，无害化认证使菜场生态效率得分提高2.7%，绿色认证提高4.6%，有机认证提高16.3%。同时，我们发现农民的认证采纳决策与农场规模、农业经验、非农收入、推广服务和社会资本显著相关，应作为政策建议加以考虑，以维持和提高认证在经济和环境方面的积极影响。

期刊介绍： Food Policy is a multidisciplinary journal publishing original research and novel evidence on issues in the formulation, implementation, and evaluation of policies for the food sector in developing, transition, and advanced economies. Our main focus is on the economic and social aspect of food policy, and we prioritize empirical studies informing international food policy debates. Provided that articles make a clear and explicit contribution to food policy debates of international interest, we consider papers from any of the social sciences. Papers from other disciplines (e.g., law) will be considered only if they provide a key policy contribution, and are written in a style which is accessible to a social science readership.
