Empirical results Parallel trend test Referring to Beck31, the parallel trend test model of Spatial-DID model is defined as: $$\begin{aligned} PM_{i,t} & = \rho_{0} \sum\limits_{j = 1}^{N} {W_{ij} PM_{j,t} } + \sum\limits_{{k = 1 - T_{b} }}^{5} {\alpha_{k} T_{i,t}^{ - k} } + \sum\limits_{{s = 1 + T_{b} }}^{10} {\alpha_{s} T_{i,t}^{ + s} } + \sum\limits_{{k = 1 - T_{b} }}^{5} {\rho_{k} \sum\limits_{j = 1}^{N} {W_{ij} T_{j,t}^{ - k} } } + \sum\limits_{{s = 1 + T_{b} }}^{l} {\rho_{s}...
