Factor taxation and labor supply in a dynamic one-sector growth model

This paper studies a class of AK-type growth models with factor income taxes, public capital stock and labor–leisure trade offs. While a higher capital tax rate reduces economic growth in the short run, the long-term growth effect is ambiguous and remains ambiguous even if the level of tax rate is larger than the degree of government externality. A higher labor income tax rate has ambiguous growth effects both in the short and long runs. However, if the intertemporal elasticity of substitution for labor supply is sufficiently small, a higher labor tax rate always lowers economic growth in the long run, despite the existence of productive government taxation.     

农产品电商发展的增收效应研究

实践已经证明,农产品电商的发展,不仅可以直接增加农产品电商从业者的收入,还可以在方便城镇居民生活的同时,间接增加城镇居民的收入。本文以15个省级单位的2131份有效问卷数据为例,实证分析了农产品电商发展的增收效应。结果发现:农产品电商发展的增收效应显著,工具变量法的实证结果与稳健性检验的实证结果也进一步证实了该研究结论。同时,农产品电商发展增收效应的发挥在很大程度上还会受诸如户主禀赋变量、家庭特征变量和区域特征变量等的影响。要进一步发挥农产品电商发展的增收效应,进一步提高农村居民收入,不仅需要采取措施稳步推进农产品电商的发展,还需要采取措施切实保障农产品产供销一体化利益链条上各利益主体的合法权益。     

我国超大城市碳排放与经济增长关系的实证研究

城市经济发展离不开能源消费,而能源消费直接导致大量的碳排放,深入研究碳排放与经济增长之间关系对超大城市实施节能减排、发展低碳经济具有重要意义。本文分别选取了上海市、北京市、天津市和重庆市1995～2014年碳排放和经济增长的相关数据,对两者的脱钩关系和格兰杰因果关系进行实证研究,得出长期内实施碳减排政策不会阻碍超大城市经济增长的结论。因此,超大城市应该积极推动低碳城市建设,不断推动产业结构升级,改善能源消费结构,积极实施节能减排政策和倡导低碳生活。     

实物资本、资本体现式技术进步与经济增长的关系研究

本文通过对安徽省实物资本与经济增长长期变动关系的研究发现,2000年后实物资本的高速增长使实物资本边际报酬与实物资本产出弹性下降速度的有所减缓,因此仔在资本体现式的技术进步阻止了实物资本利用效率的下降。在对实物资本区分为设备资本和建筑资本,并重新核算基础上,利用新古典增长模型测算出安徽省设备资本的边际报酬的变动趋势,分析得出由于仔在设备资本积累引致的资本体现式技术进步,安徽省实物资本加速积累带来的经济增长是有效率的。     

Can environmentally oriented CEOs and environmentally friendly suppliers boost the growth of small firms?

The core question addressed in the natural resource‐based view (NRBV) of the firm is how to develop and exploit resources beneficial for both the natural environment and firm performance. Due to the resource constraints and increased competition facing small manufacturing firms, achieving this is a challenge for such companies. Building on the NRBV and resource orchestration literatures, we examine the relationship between green purchasing capabilities (GPCs), CEO's environmental orientation (EO), and firm growth. Results from 304 Swedish small manufacturing firms indicate a significant relationship between GPC and growth, and this relationship is positively moderated by the EO of the CEO.     

增长极战略的实现机制与中国实践模式的重构

增长极理论是20世纪50年代新古典区域均衡发展理论遭遇危机之后的新选择,但自其诞生以来由于缺乏成功案例的支持而备受争议。我国区域非均质、不平衡使得增长极模式备受推崇,但在发展中同样遭遇困境。鉴于理论与现实鲜明的反差,以增长极的实现机制为切入点剖析了该理论的不足,指出我国三大增长极在实践中存在政府依赖刚性、自我发展能力弱、关联效应差等问题,认为完整的增长极实现机制应包括形成机制、运行机制和扩散机制,并从这三大机制入手重构了中国增长极的实践模式,提出相关政策建议。
