Abstract: On the basis of literary review, this paper analyzes the real conditions of Poyang Lake Eco-economic Zone and establishes an evaluation index system of its scientific and technological innovation capacity, which consists of five first grade indicators, twelve second grade indicators, and thirty-three third grade indicators. Then the cluster analysis method is adopted to classify the level of scientific and technological innovation capacity of Poyang Lake Eco-economic Zone into Category I, II, and III. Among them, Category I refers to the region with strong scientific and technological innovation capacity, including 10 counties (cities or districts); Category II refers to the region with medium scientific and technological innovation capacity, including ten counties (cities or districts); and Category III is the weak capacity region, including eighteen counties (cities or districts). Finally, through calculation with the method of factor analysis, it obtains the results of the size and order of scientific and technological innovation capacity of the 38 counties (cities or districts) in Poyang Lake Eco-economic Zone.
