基于面板数据的研发投入对区域经济增长影响分析

利用长江经济带110个地市1990~2013年RD投入与经济增长水平的相关面板数据,通过单位根检验、协整性检验和面板数据模型,对RD经费投入和人员投入与区域经济增长的影响进行了分析。结果表明:1长江经济带各市的经济增长与RD投入存在长期稳定的关系,RD短期投入对区域经济增长的影响则存在着一定的滞后效应;2RD人员投入产出弹性高于RD经费投入,说明区域经济增长对RD人员的依赖性更大;3RD投入表现出东部地区高于中部地区,中部地区高于西部地区,但RD投入对区域经济增长的影响则表现出中西部大于东部的现象,造成这一现象的原因在于所处发展阶段的不同和东中西区域经济特征不同。最后,从加大RD经费投入强度、制定RD投入中长期计划等方面提出了促进区域经济增长的建议。     

Footprints for Sustainability: The Next Steps

The concept of an ecological footprint is based on the understanding that every individual human appropriates a share of the productive and assimilative capacity of the biosphere. An ecological footprint corresponds to this exclusive biologically productive area that a defined population uses for all its resource requirements and wastes, and is expressed in terms of bioproductive space, with world-average productivity. Humanity's footprint or its aggregate ecological demand can only temporarily exceed the productive and assimilative capacity of the biosphere without liquidating and weakening the natural capital on which humanity depends fundamentally. Therefore, accounting tools for quantifying humanity's use of nature are essential for overall assessments of human impact as well as for planning specific steps towards a sustainable future.This paper discusses the strengths and weaknesses of the ecological footprint as an ecological accounting method, points out research needs for improvement of the analysis, and suggests potential new applications. The paper identifies ten new applications of the tool to make it applicable at various geographic scales and for a number of analytical and didactic purposes. Then nine methodological improvements are suggested that could refine the currently applied method, making assessments more sensitive to a larger number of ecological impacts. It concludes that many crucial questions pertinent to building a sustainable society can be addressed by current ecological footprint research. By making the method more complete, this tool could evolve from being largely of pedagogical use to become a strategic tool for policy analysis.     

西安市大气和水污染对人群健康损害的经济价值损失研究

环境污染对人群健康造成损害的经济价值评价一直是学术界讨论的热点．采用不同的价值评估方法-VPLL潜在寿命损失年法、VSL统计生命价值法、WTP支付意愿法对西安市1996—2003年的大气和水污染对人群健康造成的经济损失进行评价。结果表明：1996—2003年。西安市大气和水污染健康损失年平均为228792万-434237万元，占GDP的3．69％-7％。对居民健康有显着影响。     

铜陵市资源利用与经济增长关系分析

资源利用与经济增长之间的关系是资源与环境经济学研究的重要领域。以安徽省铜陵市为例,尝试运用物质流分析方法以及最新发展的自回归分布滞后模型（ARDL）对铜陵市1990~2008年资源利用和实际GDP二者关系进行检验和分析。采用了物质流分析指标中直接物质投入来表征区域资源利用量。ARDL边界检验结果表明了资源利用和经济增长间存在稳定的长期均衡关系。进一步通过ARDL-ECM模型分析了区域经济增长对资源利用长期弹性系数和短期弹性系数,并揭示出资源利用对经济增长的短期和长期因果关系。研究结果表明当前资源投入在一定程度上拉动了铜陵经济增长。同时还对铜陵经济增长和资源保护战略提出了政策建议

我国三大地带经济发展不平衡性动态分析

本文采用人均GDP指标,对1978-2002年我国三大地带经济发展的不平衡性及驱动机制进行了动态时序分析,剖析了三大地带经济差距产生的原因.结果表明:近20多年来无论是绝对差距、相对差距还是综合差距，三大地带经济区域差异均呈现扩大趋势，尤其是以20世纪90年代初期最为显著。究其原因，除了自然环境和历史背景的影响外，产业结构、所有制结构，投资强度，对外开放程度和社会文化环境等因素均具有重要影响。为缩小三大地带的经济差距，除加强对中西部的投资建设外，应加快对中西部改革开放的步伐，增强了中西部的自我发展能力。

Effect of acidic deposition on productivity of forest ecosystem and estimation of its economic losses in southern suburbs of Chongqing

In accordance with principle sand methods of ecology, this paper studied the effects of acidic deposition on productivity and volume increment of masson pine and Cinnamomum campora forest which are widely distributed in southern suburbs of Chongqing. Based on the field data and measurements, a multivariable stepwise regression model was established to analyze the effects of multiple environmental factors on the productivity of the forest ecosystems. This model was used to assess the volume and economic losses of these two forest ecosystems caused by acidic deposition. The results showed that, among the environmental factors, pH value of precipitation, soil depth, soil organic contents and slope are the dominant ones influencing the growth of masson pine forest. It is also shown that the acidic deposition has no clear relation to the growth of C.Campora forest, so development of such broad-leaved forest is suitable in the area.
