重庆市城乡二元经济结构转换研究

重庆直辖以来经济快速发展,但城乡二元经济结构也非常突出,严重影响全民小康建设进程和经济持续健康发展。以重庆直辖以来的经济数据为基础,从收入水平、消费水平、劳动生产率、城镇化等方面分析了重庆城乡二元性结构特征,结果表明:重庆城乡二元性结构差异显著,且有不断扩大趋势,其主要影响因素包括农业产业化发展缓慢、城镇工业化水平低、城镇工业对农业辐射力弱、城乡市场严重分割、传统体制约束和行政区划调整等。最后提出了加快重庆城乡二元经济结构转换的若干对策建议。     

我国收入贸易条件变动分析:1995～2004

收入贸易条件衡量的是一国在国际分工中获得的总体贸易利益的多少,在对我国贸易条件的变化进行分析时应当合理考虑收入贸易条件指数的变动。近年来我国的收入贸易条件指数呈现出持续改善的趋势,这表明外贸规模的扩大对国民经济发展做出了积极的贡献,仅仅根据商品贸易条件指数下降而得出我国贸易条件出现严重恶化的结论缺乏充分的根据。从国际经济竞争的现实背景来考虑,我国应当在保持收入贸易条件指数不恶化的情况下,继续大力推动出口贸易量较快地增长。

黑河流域生态环境保护和建设

黑河是我国西北地区一个较大的内陆河，该流域由于人口压力，林牧矛盾，水资源粗放利用，出现了严重的土地沙化，盐化，沙尘暴等生态问题，本文提出应执行抢救性水源林生态环境建设，合理配置和科学利用水资源，实施跨流域调水等补水工程，构建生态农业体系的发展方略，实现黑河流域生态良性循环，促进区域经济，社会的可持续发展。     

我国经济体制改革的回顾与展望

我国经济体制改革已有28个年头,取得了四大成就:一是市场经济引进多元化竞争;二是经济高速增长;三是人民生活水平普遍提高;四是中国的国际影响力和竞争力在提升.我国在深化改革中面临诸多的体制性障碍和结构性矛盾,可归纳为四大滞后:一是政府职能转变滞后;二是产权制度改革滞后;三是配套改革滞后;四是经济增长方式的改革滞后.我们要清楚地认识当前的形势,解放思想,坚定信心,做深化改革的促进派.     

Norwegian Emissions of CO2 1987–1994 A Study of Some Effects of the CO2 Tax

Several countries have introduced taxes on fossil fuels with the aim of reducing atmospheric emissions, partly because of local environmental goals (SO₂, NO_x) and partly to participate in a global effort to reduce emissions of greenhouse gases. Many macroeconomic studies, based on both global and national models, have been made of how emissions can be reduced with the help of taxes and the consequent reduction in GDP following the introduction of such taxes. Norway has had a CO₂ tax for five years, thereby providing a unique opportunity to evaluate the effects of this tax on emissions. The paper provides a counterfactual analysis of energy consumption and emissions if no CO₂ taxes had been introduced, compared with the actual situation in which such taxes exist. The effect of a CO₂ tax on oil consumption, and thus CO₂ emissions is studied on the basis of partial economic models for various sectors of the Norwegian economy. The study indicates that the CO₂ tax has had an impact on CO₂ emissions in Norway.     

Water accounting for the Orange River Basin: An economic perspective on managing a transboundary resource

The framework for water accounting is applied to an international river basin, the Orange River Basin, which is shared among Botswana, Namibia, Lesotho and South Africa. Each of the riparian states faces water constraints and relies increasingly on shared international water resources. The countries have adopted the principle of an economic approach to water management, once basin human needs are met, and all but Lesotho have constructed national water accounts to assist in water management. The water accounts for the Orange River Basin bring an economic perspective to water management at the regional level. The accounts include supply and use tables, which are used to compare the contribution to water supply from each riparian state to the amount used. The water accounts are then linked to economic data for each country to calculate water use and productivity by industry and country. There are considerable disparities in water productivity among the countries, which should be taken into account in future decisions about water allocation, pricing and infrastructure development.     

Does too much government spending depress the economic development of transition economies? Evidences from dynamic panel threshold analysis

This paper investigates the relationship between government size and economic growth and determines the optimal level of government spending to maximize economic growth. The paper applies a dynamic panel data analysis based upon a threshold model to test the threshold effect of government spending in 26 transition economies over the period spanning 1993–2016. According to the analysis results, government expenditures have a threshold effect on economic growth, and there is a non-linear relationship depicted as an Armey curve in these transition economies. The findings indicate that a government size above the threshold government spending level adversely affects economic growth, while a government size below the threshold level has a positive effect. Furthermore, there is a statistically significant relationship between the two variables above and below that optimal level, even if we divide the sample into developed and developing countries. Our findings suggest that governments in transition economies should consider optimal government size at around the estimated threshold level to support sustainable economic growth.
