超效率SBM模型是将超效率和SBM模型相结合的一种模型,相较于一般的径向DEA模型(如径向BCC/CCR),它考虑了松弛变量,通常被认为是更好的超效率模型。超效率DEA模型是一种广泛的概念,适用于各种实际问题。通过Stata软件,可以轻松实现SBM-DEA模型,包括超效率SBM模型的求解。0 0 发表评论 发表 作者最近动态 晓妍coca萌太...
Based on the panel data of 31 provinces in China from 2007 to 201844,45,46, Stata15.0 software was used to perform threshold regression on seven variables: per capita water resources, rural labor force, disposable income, government's attention, foreign trade dependence, industrial structure, and...
This paper applied the StataMP-64 to find the driving factors that influence carbon emissions and its efficiency of the tourist hotel. The model expression is: 𝑦*𝑖𝑡=𝑎𝑥𝑖𝑡+𝜀𝑖𝑡𝑦𝑖𝑡={𝑦*𝑖𝑡 ,𝑦*𝑖𝑡≥00,𝑦*𝑖𝑡<0 𝑖=1,⋯,𝑁 𝑎𝑛...
