Abstract: The spatial Markov chain method was adopted to explore the role of regional spatial relationships in the evolution of construction safety statues. Firstly, the construction safety statues of each province was classified into 5 different clusters by the accident rates in each province from 2012 to 2016. Then, traditional Markov chain method and spatial Markov chain method were used to construct a transfer matrix of construction safety statues respectively. Finally, the transferring probabilities of the construction safety statues in provinces of China from 2012 to 2016 were calculated under the condition of spatial lags, to analyze the influencing directions and extent of contractors from neighboring provinces on provinces with different construction safety statues. Results show that the spatial Markov chain method was more accurate in presenting the effect of regional spatial relationship on the evolution of construction safety statues, that trans-provincial contracting has a positive effect on the provinces with general and poor construction safety, but has a negative impact on the provinces with excellent and good construction safety,and that provinces with better construction safety are more resistible to negative impacts.

Key words: construction safety, accidents analysis, trans-provincied contracting, statues evolution, regional spatial relationships, transferring probability
