中文摘要：

农产品生产和贸易在全球价值链中的地位和比重相对较低。农产品生产的要素密集型特征、需求价格的弹性特征以及部分特色农产品生产技术的默会性特征均会对农产品参与全球价值链产生影响；贸易壁垒、质量安全以及信息不对称等桎梏严重制约着农产品参与全球价值链的机会和有效性；可以从明确定位、有序渐次提升价值链存在层次、灵活选择价值链驱动模式以及其他技术和组织层面考虑增强农产品生产经营企业参与全球价值链的有效性。

英文摘要：

The status and proportion for trade of agricultural products are lower than other kinds of products in world value chain （GVC）. Several important traits of agricultural products, such as factor-intensive features, price elasticity of demand and the nature of technical tacit, have large effects on its GVC activity. Trade barrier, quality safety and information asymmetry limit seriously the opportunity and effectiveness of agricultural products＇ activity in GVC. Many steps such as defining rationally orientation, selecting flexibly driving pattern and increasing orderly existential level on GVC may be taken to strengthen the participatory validity of agriculture-related enterprises in GVC.
