Institutional quality,financial development and sustainable economic growth among lower income countries

This article postulates strong endogenous relationships in lower income countries between institutional quality, financial development and sustained economic growth. These associations were investigated using the vector-error correction model (VECM) and Granger causality method for a sample of 79 countries from 2005 to 2022. The findings show that (1) these variables reinforce each other in the short run. (2) In the long run, both institutional quality and financial development can fuel economic growth. (3) The positive effect of institutional quality on economic growth is greater than that of financial development. Policy implications of these findings are that careful attention should be paid to co-development policies to enhance the institutional quality and the financial system in these economies. Policies should also consider economic growth strategies to enable sustainable economic growth rates.     

激励相容理论视角下生态公益林补偿对农户的增收效应——以福建三明为例

基于福建三明499户农户的实地调查数据,用倾向得分匹配法测算了生态公益林现金直接补偿和岗位性补偿对农户的增收效应,结果表明：现金直接补偿和岗位性补偿对生态保护和农户增收都是正效应。现金直接补偿对农户增收效应不显著,而岗位性补偿对农户家庭总收入和家庭人均收入的净效应分别达55.4%和57%。进一步研究发现,两种补偿方式对贫困户和非贫困户的增收效应也不尽相同,其中现金直接补偿不利于贫困户增收,而岗位性补偿对不同收入的农户都具有正向显著增收效应。此外,从生态公益林的根本使命出发,可以发现现金直接补偿和岗位性补偿对生态保护的净效应也存在较大差异。故此,科学规划生态补偿方式和补偿标准是实现生态保护和农户增收双重效应的根源所在。     

我国能源资源税改革对城乡居民的收入分配效应——基于CGE模型的分析

通过构建包含7个城镇居民组和5个农村居民组的多收入阶层CGE模型,并将劳动力要素分为农业劳动力、技术工人和生产工人3类,在低税率、实际税率和高税率三种情景下模拟了煤炭、石油和天然气资源税改革单独实施和同时实施对城镇和农村居民的收入分配效应,并对税收补偿措施的效果进行分析.结果表明：单独实施煤炭资源税或天然气资源税改革对城镇居民组收入差距有正向的缩小作用,有利于收入分配公平,但对农村居民组收入差距起到负向的扩大作用,不利于收入分配公平;单独实施石油资源税改革则同时缩小了城镇和居民组的收入差距,有利于收入分配公平;同时实施三类能源资源税改革的收入分配效应与税率组合方式有关;将能源资源税收入以补贴的方式返还给农村居民可以缩小其收入差距,有利于收入分配公平.     

Income and distance-decay effects on willingness to pay estimated by the contingent valuation method

This study suggests a methodology for enhancing accuracy in evaluating amenity by the contingent valuation method when household's willingness to pay (WTP) is dependent to its income and the distance between a respondent's residence and the location of a target facility. Using a linear city model, this study demonstrates the influences of income and distance-decay effects on WTP. Simulations are performed to check the validity of the model, as well as to predict consequences when income and distance-decay effects are not properly treated. Finally, the suggested methodology is applied to two real cases. The estimation results from a structural model show that the calculated total benefit varies largely when income and distance-decay effects exist and are ignored. Also, an ad hoc model generates significantly different estimates from the utility difference model this study adopted. The difference in estimates suggests that the total benefit has to be estimated by a structural model.     

家庭农场土地征收补偿问题研究

随着未来家庭农场数量的逐渐增加与经营土地面积的不断扩大,与快速城镇化相伴随的土地征收区域不可避免会与家庭农场经营的土地范围相交叉或重叠。家庭农场主通过整合作为集体经济组织成员分得的承包地和市场化交易获得的承包地实现土地适度规模经营,因此,在家庭农场土地被征收时,应确保家庭农场主获得科学合理的补偿标准,并妥善处理家庭农场主与拥有不同类型农地权利的众多相关主体之间的利益分配关系。本文采用文献资料法和理论分析法,区分点状征地、线状征地和面状征地三种不同情况,分析了家庭农场土地征收的后期生产经营影响,在土地承包关系"长久不变"的政策框架下,深入剖析了家庭农场土地征收涉及的农地权利类型。然后,构建起家庭农场土地征收补偿标准理论模型,以及家庭农场主、政府、集体经济组织、农民等权利主体之间的收益分配理论模型。具体而言,家庭农场主根据自有土地、通过土地流转获得的土地、通过土地退出获得的土地所占的比重以及不同类型土地权利所对应的价值标准分得相应的征地补偿收益;政府通过税收参与征地补偿收益分配;集体经济组织凭借土地所有者身份依法分得相应比例的补偿收益;农民获得的征地补偿收益为承包经营权价值扣除其让渡给家庭农场主的农地权利价值后的剩余部分。最后,本文从四个方面提出了相应的对策和建议:1做好家庭农场发展规划;2提高征地补偿标准并将间接损失纳入补偿范围;3建立家庭农场规模化经营土地的征收补偿收益分配机制;4保障抵押权人(金融机构)对征地补偿享有优先受偿权。     

Forest resources and household welfare: Empirical evidence from North Central Vietnam

Using secondary data from a socio-economic quantitative household survey of the North Central region of Vietnam, the main aim of our study is to analyze the causal effect of forest resources on household income and poverty. Based on the observed characteristics of a forest-based livelihood and forest-related activities, we use a propensity score matching (PSM) method to control for potential bias arising from self-selection. The PSM results indicate that households with a forest-based livelihood had a higher level of income and lower poverty rates than did those without. Interestingly, our findings confirm that a forest-based livelihood offers much higher income than any other type of livelihood adopted by local households. Also, the poverty rate among households with a forest-based livelihood is lower than those earning non-labor income or engaged in wage/crop and crop livelihoods. Among households and provinces, we find varying opportunities deriving from forest resources, suggesting that there are potential barriers hindering local households from pursuing a forest livelihood or participating in some forest activities. Therefore, government policy and regulations on forest management should focus on improving the access of households to forest resources, while enhancing the sustainability of these resources.     

中国省际间农村居民收入结构和收入差距分析

在计算基尼系数的基础上,文章得出了改革开放以来中国省际间农村居民收入差距不断扩大的趋势,收入基尼系数从1981年的0.095一直上升到了2003年的0.181,直到近年来,收入差距才开始略有缩小。文章从收入结构的视角研究了省际间农村居民收入差距产生的原因。首先利用1983-2008年较长时期的数据分析了农村居民收入结构的变化,发现从总体上而言,中国各地区农村居民的收入结构均表现出了农业收入比重减少,非农收入比重增加的明显趋势;然后运用基尼系数的分解方法实证分析了不同收入来源对于收入差距的影响,研究发现,工资性收入是差距促增的,是目前中国省际间农村居民收入差距扩大最重要的原因,而家庭经营性收入者起着差距促减的作用,转移性收入和财产性收入的不平等程度较高,但是由于其在总收入中的比例不高,对总的收入差距影响较小。最后,文章提出了缩小省际间农村居民收入差距的政策建议。     

Income Growth, Urbanization, Changing Life Style and Energy Requirements in China

This paper aims to estimate the effects of changing life style and consumption demands driven by income growth and urbanization on increase of energy requirements in China, and es-timate the impacts of improvement in household consumption on mitigating energy requirements towards 2020, based on input-out-put analysis and scenarios simulation approach. The result shows that energy requirement per capita has increased by 159% for urban residents and 147% for rural residents from 1995 to 2004. Growth in household consumption driven by income growth and urbanization may induce a successive increase in energy require-ments in future. Per capita energy requirements of urban residents will increase by 240% during 2002-2015 and 330% during 2002-2020. Urbanization might lead to 0.75 billion ton of increment of energy requirements in 2020. About 45%-48% of total energy requirements in China might be a consequence of residents’ life styles and the economic activities to support consumption demands in 2020. Under low-carbon life style scenario, per capita energy requirements of urban residents may decline to 97% in 2015 and 92% in 2020 in contrast with baseline scenario. That implies that China needs to pay a great attention to developing green low-carbon life style in order to realize mitigation target towards 2020.     

不同收入来源对甘肃省城乡收入差距的影响研究

收入由多个来源部分组成,城乡收入差距的变化是收入来源各部分变动的综合反映,透过收入来源的角度可以清晰地判断城乡收入差距产生的根源.本文运用泰尔指数及其分解方法,对2003-2008年甘肃省城乡收入差距大小及其在总区域收入差距中的贡献变化趋势进行测度,并利用要素分解法实证分析了不同收入来源对城乡收入差距的影响,以此揭示甘肃省城乡收入差距产生的原因.研究发现,城乡收入差距在总区域收入差距中的贡献是递增变化的,已经成为影响甘肃省居民收入差距的重要因素;工资性收入是目前拉大城乡收入差距最为重要的原因,而家庭经营性收入则起着缩小差距的作用,转移性收入和财产性收入在总收入中所占比例很小,但转移性收入对城乡收入差距的贡献却不容轻视.基于研究结果,提出了增加农民非农收入、推进农业产业化进程和完善城乡间收入再分配制度等政策建议,以期为欠发达地区缩小城乡收入差距带来一些启示.
