The effects of vertical and horizontal incentives on local tax efforts: evidence from China

Tax effort is a measure of a government's effort to collect taxes. This study explores what impacts both vertical and horizontal incentives have on local governments' tax efforts in China. For consistency with the literature, we first include typical economic and institutional factors in our analysis. We find that the effects of economic factors on local tax efforts are significant, but the effects of institutional factors tend to be weak. Fiscal decentralization, as a vertical incentive, has a significantly positive effect on tax efforts at the provincial level. Meanwhile, fiscal interaction, as a horizontal incentive, is also taken into account in a spatial specification to explain tax competition among local governments. The results show that local tax effort in China also depends on the horizontal incentive. Hence, to improve local tax effort, the central government should let the locals have more autonomy in collecting taxes and evaluate local tax effort by referring to tax collection in adjacent provinces simultaneously.
