居民消费水平对生活碳排放的门槛效应研究

Threshold effects of household consumption level on residential carbon emissions

为进一步促进居民可持续消费、打造低碳生活方式,基于2000~2013年我国29个省区的数据,利用非动态门槛面板模型考察了居民消费水平对生活碳排放影响的门槛效应与地区差异。结果表明:居民消费水平对生活碳排放的影响存在显著的门槛效应。城镇化水平小于门槛值,居民消费水平会对生活碳排放有较强的增长作用,越过门槛值时,这种增长作用有所减缓;随着居民生活煤炭消费比例的提升,居民消费水平对生活碳排放的增长作用越来越强。另外,居民消费水平对生活碳排放的影响存在显著的地区差异。最后,提出鼓励居民可持续消费和抑制生活碳排放的相关对策建议。

For further promoting sustainable household consumption and establishing the low - carbon lifestyle, based on the data of 29 provinces from 2000 to 2013, a panel threshold model was built to study the effect of household consumption level on residential carbon emissions and the regional differences. Results show that the threshold effects were significant. When urbanization level was less than the threshold, the impact of household consumption level on residential carbon emissions was positive, then the positive impact was weaken while urbanization level was over the threshold. With the proportion of coal consumption increasing, the positive impact of household consumption level on residential carbon emissions was more and more stronger. In addition, there were significant regional differences of household consumption level on residential carbon emissions. Finally, some suggestions are proposed to advocate sustainable household consumption and restrain the residential carbon emissions.
