消费分层与环境优化:基于流通效率提升的诠释

Consumption Stratification and Environmental Optimization: an Interpretation based on Circulation Efficiency Improvement

解决好提升流通效率与缩小消费分层的内在关联,对于进一步发掘居民消费潜力具有重要意义。本文利用包含非期望产出的EBM-DEA模型对流通效率进行分析,并结合共同前沿下的MML指数对其进行动态测度和分解;进一步从绝对消费水平和消费结构等维度对城乡层面的消费分层展开量化分析,进而构建面板门槛模型,流通效率提升对于消费分层具有非线性影响。研究发现:我国流通效率呈现不断提高的趋势,且地区间流通效率差异显著;缩小城乡居民消费分层特征典型,现阶段城镇居民消费在绝对消费支出总量和消费质量等方面明显高于农村居民;流通效率提升对于消费分层具有“先促增、后抑制”的动态非线性影响。据此,应大力侧重和扶持农村地区的物流设施建设,坚持“以城带乡、城乡一体”策略,推动城乡消费协同发展。

Addressing the intrinsic correlation between improving circulation efficiency and narrowing consumption stratification is significant for further exploring residents’ consumption potential. This paper analyzes the distribution efficiency by using the EBM-DEA model with non-expected output, and dynamically measures and decomposes it by combining the MML index under the common frontier;further quantifies the consumption stratification at the urban and rural levels in terms of absolute consumption level and consumption structure, and then constructs a panel threshold model, in which the distribution efficiency improvement has a non-linear impact on the consumption stratification. It found that the circulation efficiency in China is improving continuously, and the difference in circulation efficiency between regions is significant;the consumption stratification between urban and rural residents is typical, and urban residents consumption is significantly higher than that of rural residents in terms of total absolute consumption expenditure and consumption quality;the improvement of circulation efficiency has a dynamic nonlinear impact on consumption stratification of "promoting increase first and suppressing later". The improvement of circulation efficiency has a dynamic non-linear impact on consumption stratification. Accordingly, we should focus on and support the construction of logistics facilities in rural areas, adhere to the strategy of "leading the countryside with the city and integrating the countryside with the city", and promote the synergistic development of urban and rural consumption.
