西北地区自然资源开发与经济增长的关系研究——基于面板数据的实证分析

本文采用面板数据对西北地区资源开发与经济增长之间的关系进行了研究,证明了西北资源开发与经济增长之间存在长期稳定的协整关系,并应用面板回归模型对西部大开发前十年和近九年西北资源开发与经济增长的关系进行了对比分析,最后针对分析结果提出两点建议。     

纯净水对斑马鱼幼鱼生长发育的影响

本文研究了纯净水对斑马鱼幼鱼生长发育的影响。研究发现,纯净水组中养殖的斑马鱼幼鱼在体长、侧面投影面积及眼大小等方面显著低于天然水组和正常对照组,而卵黄囊面积则显著高于天然水组和正常对照组;且与其他两组相比,纯净水组的斑马鱼有脊柱弯曲及心率减缓等致畸现象出现。由此可见,几乎不含任何矿物元素的纯净水不但会能延迟斑马鱼幼鱼的生长发育,且还有一定的致畸作用。     

矿井采空区瓦斯抽放

Mine gas is the concomitant during the process of coal formation. Its main composition is methane, methane is colorless, odorless, tasteless, lighter than air, and relative density is 0.554. In order to reduce and eliminate threat to safety coal mine production, we use the mechanical equipment and pipelines cause negative pressure, pump the gas existing or release in the coal seam and transport it to the earth or other safe places, which is called gas drainage.     

"资源诅咒"视角下的西部地区经济增长

西部地区自然资源富集,但经济增长相对缓慢,出现了"富饶的贫困",存在着所谓的"资源诅咒"。自然资源丰富在某种程度上确实是经济增长的优势,但如果开发利用不当,或仅仅将眼光集中在资源上,就很容易转化为经济发展的劣势。资源丰富的西部地区必须跳出资源诅咒,实现经济快速健康增长。     

海洋资源资产分类与核算框架研究

海洋作为国家的基础和战略资源,是国家重要的生存财富与保障,开展海洋资源资产分类与核算框架研究是挖掘海洋资源的市场价值,集约高效调控海洋开发管理活动的基础前提。本文分别从法律与经济两个层面剖析自然资源类别,并综合资源和资产双重属性,将海洋资源划分为海洋生物资源、海洋矿产资源、海洋空间资源与海水资源四大类,并进一步深入探索海洋资源资产核算框架,构建海洋资源资产核算表式结构与价格评估方法,最终从产权制度、用途管制、有偿使用与生态补偿4个方面为海洋资源资产化管理提出了探索方向。     

Income comparisons and attitudes towards foreigners - Evidence from a natural experiment

We exploit a natural experiment related to the German re-unification to address whether disutility from income comparisons affects attitudes towards foreigners. Our empirical approach rests upon East German individuals with West German relatives and friends. We use the exogenous variation of wealth of West Germans shortly after the fall of the Berlin Wall as an instrument to identify the effect of disutility from income comparisons on East Germans’ attitudes. We find robust evidence that East Germans express more negative attitudes towards foreigners, particularly from low-wage countries, if they worry about their economic status compared to better-off West Germans.     

The impact of government debt on the long-run natural real interest rate – a quantitative evaluation

Persistently low natural real interest rates are a problem for monetary policy and financial stability. I analyse to what extent a permanent increase in government debt that is financed by higher taxes could raise the long-run natural real interest rate. As a measurement tool, I use an incomplete markets model with capital and government bonds. Increasing the public debt/GDP ratio by one percentage point raises the real interest rate by between 0.4 and 1.5 basis points, depending on the degree of inequality generated by the model and the tax instrument used to balance the government’s budget constraint. I also show that the interest rate effect of a change in public debt/GDP predicted by the model is significantly smaller than its empirical counterpart for the US, due to the fact that the model understates the empirical fraction of households that are constrained in their consumption decision.     

Natural resource dependence, non-tradables, and economic growth

I argue that the commonly used nominal measure of natural resource dependence – the share of exports of primary products in GNP – understates in growth regressions the negative link between natural resource dependence and per capita GDP growth. I show that using a purchasing power parity adjusted measure yields an economically much larger negative relationship between per capita GDP growth and natural resource dependence than what has been suggested by the nominal measure. Consistent with the rent-seeking literature, I show that the resource curse is a symptom of societies characterized by high levels of corruption and sluggish checks and balances on political decision-making.     

全球气候变化下碳排放与交易的会计问题:最新发展与评述

由于CO2大量排放,不仅使全球气候变化问题更加严峻,而且给企业带来了巨大的财务影响及会计处理难题。近年来,国际会计学界、相关机构及协会纷纷对二氧化碳排放所引起的会计问题展开理论研究和实务探讨,并取得了一系列的进展。本文介绍了当前国际研究机构及相关研究者就碳排放与交易的会计处理、规范所作的努力和最新研究成就,同时也提出了我国发展碳排放与交易的会计规范所需注意的原则及相关建议。
