Operation projects are the bases of agricultural industry development. What's more, they are important contents of adjusting agricultural industrial structure and improving agricultural comprehensive production capacity under the background of collaborative development in the Beijing-Tianjin-Hebei region. Based on the data of agricultural industrialization management projects in the study area from 2011 to 2016, this paper analyzes the spatial distribution and influencing factors using nuclear density index and other analysis methods. The results showed that: (1) The spatial distribution of operation projects formed an "oblique line" structure nuclear density, which declined from the central part to northeast and southwest. (2) Planting base projects were mainly distributed in southwest Hebei province and east Tianjin maunicipality, and breeding base projects were mainly in south Hebei and central Tianjin. Storage and fresh preservation projects as well as reconstruction and expansion processing projects were respectively transferred to the central north and northeast of the Beijing-Tianjin-Hebei region. (3) The distribution of operation projects were influenced by the total power of agricultural machinery and loan balance of financial institutions, which directly affected the "hardware" conditions of agricultural development and the supply of supporting funds.
