Abstract: The paper shows the advances of efects of CO₂ enrichment and climate change on the agriculture inside and outside the country including the impacts of elevated CO₂ on crop productivity，interactive effects of temperature increase and atmospheric C0₂ concentration，and interactive efects of water availability and atmospheric CO₂ concentration．The study shows that the crop productivity，such as economical yidds and biomass，and water utilization efficiency，increases with CO₂ concentration increase，but high temperature may have negative effect on the crop prod uctivity．The efects of CO₂ enrichment and climate change should need further research．
