How mitigation efforts moderate the impact of climate change on agricultural efficiency: a preliminary analysis from China

ABSTRACT

In this paper, we empirically evaluate the effect of climate change on agricultural technical efficiency, considering the moderating effect of mitigation efforts based on emission reduction in China. In particular, we directly measure the intensity of mitigation efforts using the climate change mitigation index. We then apply the two-stage double bootstrap DEA method to build up the empirical model, effectively avoiding biased estimation using the traditional two-stage DEA method. Our results show that the intensity of mitigation measures moderates the impacts of global warming on efficiency and mild mitigation measures are better than drastic ones.
