Evaluation of Industrial Chain Integration Driven by Technology Integration of Characteristic Tropical Crops

doi:10.13304/j.nykjdb.2022.0841

Abstract

Abstract:

Characteristic tropical crops play an important role in promoting rural revitalization and serving for “the Belt and Road Initiative” in China. Taking China’s characteristic tropical crop industry as research object， and based on surveyed micro-data and macro-data from the FAO， this paper systematically explained the production situation of tropical crops in China and the connotation of technology integration. PSM-DID method was used to test the marginal effect of farmers’ participation in “industrial chain integration development technology project” on reducing production cost in the development process of China’s tropical crop industry. It was found that participating in the “cassava industrial chain integrated development technology project” could significantly reduce the fertilizer cost of cassava by 24.0%， reduce labor costs by about 19.0% and reduce pesticide input costs by 9.1%. Some countermeasures were proposed to cope with the uncertain climate environment in the future， such as constructing soil quality monitoring system of artificial microbial community， strengthening the innovation and research of soil health regulation technology， and strengthening the mining of favorable genes of germplasm resources of characteristic tropical crops etc.

Key words: characteristic tropical crops, PSM - DID method, technology integration driven, integrated development of industrial chain

摘要：

特色热带作物在促进我国乡村振兴和服务“一带一路”倡议中起着重要作用。以我国特色热带作物产业为研究对象，基于实地调研微观数据和FAO宏观统计数据，对中国特色热带作物生产情况及技术集成内涵进行了解释说明。运用PSM-DID方法检验了中国特色热带作物产业发展过程中农户参与“产业链一体化发展技术项目”对降低生产成本的边际效应。研究发现，参与“木薯产业链一体化发展技术项目”能显著降低化肥成本24.0%，显著降低约19.0%的人工成本和9.1%的农药投入成本。提出了构建人工微生物群落土壤质量监测系统、加强土壤健康状况调控技术的创新研发和加强特色热带作物种质资源有利基因挖掘等应对未来不确定性气候环境的对策建议。
