随着资源环境约束日益缩紧,走生态优先的绿色发展之路已经成为社会共识,而发展方式的变革不仅需要转变传统的生产方式,也需要改变不环保的生活方式。该研究从生产方式和生活方式绿色转型视角出发,以2014—2020年中国30个省份的截面数据为案例样本,使用模糊集定性比较分析方法(fsQCA),探究高(非高)水平绿色发展的组态效应及其时间演变趋势和空间组态差异。结果表明:①单一条件不是实现高水平绿色发展的必要条件,非产业绿色转型是导致非高水平绿色发展的必要条件。②根据重要影响因素的异同将5条高水平绿色发展的驱动路径划分为产业-效率-需求驱动型、产业-需求驱动型和效率-需求驱动型;非高水平绿色发展的驱动路径有3条,绿色技术创新、产业绿色转型和绿色消费需求缺失是导致非高水平绿色发展的主要原因。③绿色发展的驱动路径具有空间异质性,东部地区绿色发展驱动路径具有一致性和完备性,中西部地区驱动路径更加多元和分散。④随着时间的推移,绿色产品需求和绿色消费能力在推动绿色发展中发挥着越来越重要的作用。基于上述研究结果,该研究提出不同地区应因地制宜,根据自身发展情况选择最佳绿色发展路径:高水平绿色发展地区要在深化自身优势的基础上推动绿色生产、生活方式的协同发展,低水平绿色发展地区需明确自身发展短板,集中优势资源突破生产、生活方式绿色转型方面制约绿色发展的关键因素。

绿色税收政策分为绿色税征收政策和优惠政策,不同的绿色税收政策组合对绿色发展的影响会有显著的差异。通过扩展环境技术进步方向模型来推导绿色税收政策的技术偏向,可以实证检验不同的绿色税收政策及其组合对绿色发展的具体影响。检验结果表明:两种绿色税收政策都能促进技术进步朝绿色方向转变并改善环境质量,绿色税征收政策对环境质量的改善效果更好,但绿色税征收政策会抑制经济增长,而税收优惠政策则能促进经济增长。综合来看,绿色税收优惠政策能促进绿色发展,绿色税征收政策对绿色发展的影响呈现先减后增的“U”型变化;绿色税收政策组合对绿色发展的促进作用优于单项政策,最优的绿色税收政策组合是动态变化的。因此,现阶段中国需要通过降低绿色税征收政策强度、适当提升绿色税收优惠政策力度来推动绿色发展。
