Abstract:To comprehensively examine the contribution to agricultural growth brought about by a series of government regulations,based on the FAO data for 45 countries worldwide,this paper selected the World Bank’s regulatory indicators of quality to verify the impact of government regulation on agricultural economic growth and the action path,and compared the differences in the influence under different industries.It found that the high-quality government regulation for private sector could directly promote agricultural economic growth,and there was an indirect impact of agricultural factors as intermediaries.Government regulation promoted land regulation output elasticity but inhibited contributions of labor forces and government spending on agriculture.These effects,direct or indirect,occurred mostly in the agricultural economy dominated by livestock husbandry but rarely in the agricultural economy dominated by farming.
