土地发展非均衡度测算及其敏感性分析——基于农地非农发展受限视角

论文以农地非农发展受限为研究对象,分别基于用地结构和土地财事权视角构建土地发展非均衡度模型,并在此基础上依据二者对经济发展的贡献度确定权重,进行加权求和,求算土地综合非均衡度。基于我国2009—2013年省级面板数据的实证研究结果表明：总体上,我国的土地发展非均衡度较高,但逐年下降;省级层面上,我国土地发展非均衡度的空间差异显著,且非均衡度呈“东部沿海发达地区—中部地区—西南地区或东北、西北地区”逐级递增趋势。此外,论文就土地发展非均衡度对财政转移支付的敏感性进行分析,为我国财政转移制度改革奠定理论依据。结果表明,财政转移制度有助于减缓土地发展非均衡度,且四大分区的土地发展非均衡度对财政转移支付的敏感性存在显著差异。研究尝试直接量化土地发展非均衡程度,为缓解土地非均衡发展、均衡区域发展奠定理论基础。     

An environmental tax-shift with indirect desirable effects

Imposing environmental taxation on external costs of energy will not only affect the environmental impact of the energy sector itself, but it will tend to decrease environmental damage from other sectors of the economy as well. We have assessed the effects of a shift of taxation from taxing labour to taxation of external costs caused in the energy sector. Several examples give results compatible with the hypothesis that the changing price relation between labour and energy resulting from such a tax shift will make re-use, repairs and recycling increasingly competitive and thus tend to decrease mining as well as waste production. Likewise, less energy-intensive commodities and services in general would become increasingly competitive, and would tend to decrease the environmental load further. These environmentally desirable effects are beyond the taxed external effects of the energy sector itself and occur as an indirect effect of the increased relative price of energy.     

Planning in the countryside

The author considers the present greater awareness of the needs of the countryside brought about through public debate of the issues involved. The nature of countryside policies is considered and recent developments described. The paper concludes that much more positive planning is being undertaken to conserve the countryside, whilst allowing rural development to take place.     

What determines the success and failure of environmental crowdfunding?

Online crowdfunding can help address the perennial financial shortfalls in environmental conservation and management. Although many online crowdfunding campaigns fail to collect any funds due to not achieving their targets, little is known about what drives success. To address this knowledge gap, we applied a mixed-methods approach to data from 473 successful and failed campaigns hosted on the online crowdfunding platform Readyfor. We found that fundraising performance varied by topic, with campaigns on pet animal management outperforming those focussed on landscape management and sustainable use. We also found that marketing strategies associated with online findability and increased reach through social networks, increased fundraising success. However, the existence of other environmental campaigns running simultaneously, reduced the chance of success, which implies that the selecting popular topics does not always increase the likelihood of success due to increased competition. Wider applications of marketing could enhance the ability of environmental crowdfunding campaigns to raise funds.Supplementary InformationThe online version contains supplementary material available at 10.1007/s13280-021-01522-0.
