Evaluating the price policy of raw milk is of great significance to the sustainable development of an industry supply chain. In this context, our study used the multi-period difference-in-difference method to systematically examine the impact of the policy implementation on product price and profit distribution in the supply chain. The results showed the following: (1) the price of raw milk in the implementation area of the price support policy is 13.54% higher than that of the unimplemented area; (2) the effect of price increase in the western region (15.5%) is higher than that in the eastern region (13%), and the central region (10.73%); (3) furthermore, the purchase price guidance policy of raw milk drives price increase or price suppression in the links of the supply chain to promote a balanced distribution of profits among the participants in the chain. These conclusions all have good stability and have reference significance for further improving and adjusting the price support policy of raw milk to realize the sustainable development of the Chinese dairy industry. This will enhance the production confidence of Chinese raw milk producers and improve Chinese consumers' expectations and consumer psychology regarding domestic dairy products.
评估生鲜乳价格政策对产业供应链的可持续发展具有重要意义。在此背景下，本研究运用多期双重差分法系统考察了政策实施对供应链中产品价格和利润分配的影响。结果表明：（1）价格支持政策实施地区的生鲜乳价格比未实施地区高13.54%；（2）西部地区价格上涨幅度（15.5%）高于东部地区（13%）和中部地区（10.73%）；（3）此外，生鲜乳收购价格指导政策促使供应链各环节价格上涨或下跌，以促进产业链参与者之间利润的均衡分配。这些结论都具有良好的稳定性，对进一步完善和调整生鲜乳价格支持政策、实现中国乳业可持续发展具有参考意义。这将增强中国生鲜乳生产者的生产信心，改善中国消费者对国产乳制品的期望和消费心理。
