It reached following conclusions: (i) under the influence of macro factors and micro factors, bribery behavior of developers is rational selection after full consideration of institutional environment and corporate strength, and is passive to a certain extent; (ii) bribery behavior of developers has certain spatial correlation, and the high-high correlation characteristic is most significant.
