Water resources are an important factor that affects rural social and economic development and farmers’ income. This study starts from the goal of coordinating the government and farmers on efficiency and income,based on the survey data of 357 vegetable growers of the main vegetable production area in the Bohai Rim in 2017, applied the simultaneous equations model (SEM), conditional mixture process (CMP), propensity score matching (PSM), and instrumental variable quantile regression (IVQR) to investigate the efficiency and income increase ability of drip irrigation technology and the constraints of promotion effect at the micro level, to explore the path to promote sustainable development of China’s agriculture. The results show that: (1) In the main production areas facing severe water scarcity, households with fewer years of planting, abundant capital, and higher level of knowledge on water saving tend to adopt drip irrigation technology; (2) Drip irrigation technology has significant effects on increasing production efficiency and income. The output of unit irrigation water and income on average increase by 17.16 kg/t of vegetables and 45.90 yuan/t for farmers who adopt the drip irrigation technology, which provides long-term incentives for its broader adoption; (3) The output and economic effects of drip irrigation technology have a “Matthew effect,” which means that farmers with better production conditions benefit more from the technology; (4) Imperfect design of irrigation system, poor design and quality of equipment engineering, inadequate training and after-sales service, lack of professional knowledge and technology of farmers, weak ability to practice modern agriculture, and poorly designed subsidies of the government are important factors affecting the enthusiasm of farmers to adopt drip irrigation technology. Furthermore, proper increase of irrigation water price will help speed up the popularization of field water-saving technology.
