摘要翻译：
越来越多的政策关注和关于非关税措施的激烈学术辩论促使越来越多的文献研究非关税措施如何影响农业食品贸易。实证文献提供了对比和异质的证据，一些研究支持标准作为催化剂的观点，另一些研究支持标准作为障碍的解释。就非关税壁垒能够影响贸易而言，了解其普遍影响以及其中一种影响背后的动机是一个紧迫的问题。我们回顾了大量关于非关税措施对农业食品贸易影响的经验证据，并进行了荟萃分析，以解开估计中异质性的潜在决定因素。我们的发现显示了出版过程和研究特定假设所起的作用。这些研究的一些特征与正显著性估计相关，另一些特征与负显著性估计相关。总的来说，我们发现NTMs的影响因NTMs类型、代理NTMs和研究细节的不同而异。不可忽视的是方法问题和出版过程的影响。

英文摘要：
  The increasing policy interests and the vivid academic debate on non-tariff measures (NTMs) has stimulated a growing literature on how NTMs affect agrifood trade. The empirical literature provides contrasting and heterogeneous evidence, with some studies supporting the standards as catalysts view, and others favouring the standards as barriers explanation. To the extent that NTMs can influence trade, understanding the prevailing effect, and the motivations behind one effect or the other, is a pressing issue. We review a large body of empirical evidence on the effect of NTMs on agri-food trade and conduct a meta-analysis to disentangle potential determinants of heterogeneity in estimates. Our findings show the role played by the publication process and by study-specific assumptions. Some characteristics of the studies are correlated with positive significant estimates, others covary with negative significant estimates. Overall, we found that the effects of NTMs vary across types of NTMs, proxy for NTMs, and levels of details of studies. Not negligible is the influence of methodological issues and publication process.
