Heilongjiang Province proposes to build the food and agricultural product deep processing industry into the first pillar industry in the province. As an important grain production base, Heilongjiang Reclamation Area shoulders a heavy responsibility in promoting the transformation and upgrading of agricultural product processing industry and achieving high-quality development, the current development trend of agricultural product processing industry in the reclamation area is good: the industrial scale is constantly expanding, the industrial and social benefits are steadily increasing, and the brand value is gradually reflected. However, there is still a low level of industrial deep processing, the innovation ability of agricultural product processing technology is still weak, and the problems such as asynchronous growth of brand and economic benefits. In view of this, the path to promote the high-quality development of agricultural product processing industry in Heilongjiang Reclamation Area is proposed from the perspectives of extending the industrial chain, expanding brand influence, and increasing investment in scientific and technological innovation.
