中国的政府公共支出与减贫政策

在中国 ,尽管农村经济增长和贫困减少取得了长足进展 ,但很少有研究对农村经济的动力源进行分析 ,而把公共投资作为农村发展和消除贫困的直接动力源的研究尤其缺乏。本文旨在弥补以前研究的空白 ,并指出各类公共投资对农村经济增长、贫困减少和地区不均等的边际效应在各地区和各时期差别很大。根据实证结果和对历史上公共支出方式的分析可知 ,农村公共支出再分配可以带来很大的潜在收益。     

Recent rural growth in China: the performance of the rural small-scale enterprises, 1980–86

This article focuses on the evaluation of the process of growth in rural China since the 1978 rural economic reforms. By dividing the rural economy into two sectors: the agricultural sector and the RSE (rural small scale enterprises) sector, it analyses the relative contributions of labour, capital and other factors. Two major findings are that the RSE sector has its marginal labour productivity double that of the agricultural sector over 1980–86 and the high-income regions (mainly the coastal provinces open to world exports) exhibited a positive role of increasing returns to scale. This trend lends strong support to the market-based incentives offered by the openness in free trade which influenced the coastal provinces of the RSE sector.     

农村基础设施公共投资与农业增长——基于省际面板数据的例证

农业增长离不开生产要素投入的增加和农村基础设施的完善。由于农村基础设施具有技术不可分性、低排他性、不可贸易性等特征,因而应当主要由政府的公共投资来提供。运用1994—2009年期间中国各省、市、自治区的面板数据,通过模型的比较分析,发现耕地投入和农业劳动力投入是不断递减的,但由于农业经营制度变革、公共投资增多、农业技术进步导致劳动生产率提高等原因,农业总产值仍稳步提升。农田水利灌溉、农业科研、农村教育和农村电力等方面的公共投资都能推动农业增长,但由于各项投资的边际影响不同,需要在不同地区有所侧重。研究还发现,农村基础设施公共投资能够明显缩小西部地区与中东部地区的农业发展差距,促进区域经济协调可持续发展。     

黑龙江省农村金融领域的信用风险及其防范

信用是市场经济的基础,也是市场经济的必然产物,因此,信用风险一旦发生就会对经济发展产生诸多不利影响,在金融领域的影响尤为严重。中国作为一个农业大国,农村金融领域发生信用风险就会严重地制约经济的总体发展水平。因此,从农村金融的角度,以黑龙江省为例,提出合理防范农村金融领域的信用风险,对黑龙江省整体县域经济发展具有重要意义。基于此,分析了农村金融领域信用风险产生的原因和对区域性农业经济发展的影响,提出了相应的风险防范措施.     

论中国农村全面转型

当前，中国农村发展进入了全面转型的新阶段。虽然中国农村全面转型具备了条件，但也面临一些阶段性挑战，突出表现在高成本严重损害农业竞争力、农业机械化亟待转型升级、“谁来种地”难题尚未破解、农业适度规模经营任重道远、农民增收的压力不断增加、农村资源资产浪费严重、农村生态环境亟待改善、乡村治理模式仍需创新八个方面。而且，现有的一些思想认识、体制机制、法律法规和政策，也阻碍了农村全面转型，束缚了农村发展。促进农村全面转型发展，需要以综合配套、整体推进的方式深化农村改革，并着力提高农村资源资产的流动性，系统开展农村集体产权制度改革，加快构建新型农业经营体系，深入推进农业供给侧结构性改革，不断完善农业支持保护政策。     

我国农村地区的技术进步——基于空间计量经济学

利用1999—2008年广东省的市域数据,基于空间面板模型对其农村地区的技术进步模式进行了实证分析。结果显示:该地区的农村技术具有明显的空间相关性,且这种空间相关性随经济发展有逐渐增强的趋势;农村技术进步的途径主要有三种,即区域内农村研发创新、城市先进技术溢出以及农村地区间技术扩散;以农村投资为代表的"干中学"以及农村地区间的技术扩散是农村技术进步的主要动力;受农村吸收能力弱等因素的限制,城市先进技术溢出较其他两种途径对农村技术进步的影响较小,但仍是农村技术进步的重要来源。最后提出,加强农村科技投入,提高农村自主研发和创新能力,提高农村地区的消化、吸收能力以及促进农村地区间的技术扩散,是解决"三农"问题的重要渠道。     

我国农村正规金融与非正规金融效率分析

高效率的金融制度对经济发展提供强有力的资金支持,可以提高经济的总体竞争力,促进经济增长。对农村信用社、农业银行、农业发展银行和邮政储蓄银行等正规金融机构和村镇银行、小额贷款公司等非正规金融组织的效率进行调查,从资金配置效率、适应性效率和运行效率方面进行分析,结果显示：正规金融制度的效率偏低,非正规金融组织的效率偏高;两种金融制度的效率有各自的空间,在规模和范围较小时,非正规金融制度效率更高,而超出一定的发展范围和规模,正规金融制度的优越性则进一步凸显。     

收入差距、劳动力流动与粮食生产

由收入差距引起的农村劳动力向城市和非农业转移在一定程度上对粮食生产产生负面影响。根据1990-2010年间省级面板数据估计结果,以2004年为分界点,2004年之前的收入差距对粮食增长具有显著的负面作用。根据经济发展程度和粮食安全状况将全国各省分为四类区域,欠发达地区粮食增产与地区经济差距的关系最明显。应重视缩小区域差距,加大对欠发达地区的投资,在当地创造就业机会,吸引农村劳动力回流,以促进当地农业生产。     

Structural Change and Economic Growth in China

This study develops a new analytical framework to account for sources of rapid economic growth in China. The traditional Solow approach is expanded to include another source of economic growth—structural change. The empirical results show that structural change has contributed to growth significantly by reallocating resources from low‐productivity sectors to high‐productivity sectors. It is found that the returns to capital investment in both agricultural production and rural enterprises are much higher than those in urban sectors, indicating underinvestment in rural areas. On the other hand, labor productivity in the agricultural sector remains low, a result of the still large surpluses of labor in the sector. Therefore, further development of rural enterprises and an increase in labor flow among sectors and across regions are key to improvements in overall economic efficiency.     

农村正规金融会抑制经济增长吗?——以陕西为例

基于陕西省1978年～2009年时间序列数据,分别运用Johansen协整检验,向量误差修正模型和方差分析方法对陕西农村正规金融与经济增长的长期和短期关系进行检验。结果表明:短时期内,农村正规金融对经济增长具有正向促进作用,按其贡献率的大小分别是农村正规金融发展水平、资本边际生产率、农村金融体系效率以及农村储蓄率,但各变量的长期关系反映出农村正规金融发展水平和效率会对农村经济增长产生抑制作用。     

The effects of education in early-stage agriculture: some evidence from China

The stochastic production frontier approach is used to study the effects of education on agricultural efficiency for a cross-section of 'early-stage' farms from Guanghan County, Sichuan Province, China. Education for farm families in rural China is multifaceted with a combination of formal education, intragenerational transfer of knowledge within the home, and agricultural extension services. Since our survey data span two different years with markedly different policy environments, we are able to examine not only which aspects of education affect agricultural efficiency, but also whether or not the policy environment matters. We find limited evidence that in a policy environment that is conducive to agriculture, formal education provides positive returns in agriculture. Furthermore, general education may provide greater returns than the more targeted extension services.     

农村劳动力流动对农业发展的影响——基于超越对数生产函数

农村劳动力流动是一个长期的过程,会对传统的农业生产方式和农村资源配置结构产生冲击.新一代劳动力的彻底性流动激发了农村要素结构的重组,促进了农村生产方式的产业化和市场化转型,农业生产效率和技术水平得到了显著提高.但在带来诸多积极影响的同时,也产生了一定的负面效应,例如农业生产者老龄化、妇女化;土地流转滞后;农村基础设施薄弱等.可通过改善农业生产条件吸引高素质人才,完善土地流转机制和农村社会保障制度,加大农业基础设施化投资力度等对策化解这些不利影响.     

Allocation of Labor in Urban West Africa: Insights from the Pattern of Labor Supply and Skill Premiums

Using comparable data from five West African capitals, we assess the rationale behind development policies targeting high rates of school enrollment through the prism of allocation of labor and earnings effects of skills across the formal and informal sectors, and not working. We find that people with high levels of education allocate to the small formal sector, while less educated workers allocate to the informal sector. While high levels of education are given more value in the relatively smaller sectors of salaried employment, observed skills like education appear to be fairly unprofitable in the larger self-employment sector. The fact that only the small formal sector in urban West Africa both seems to absorb highly educated workers and provide high skill premiums may be an important reason for the observed low demand for education and high dropout rates.     

Foreign aid,institutional quality and economic growth: Evidence from the developing world

This paper examines the effect of sectoral foreign aid and institutional quality on the economic growth of 74 developing countries from Africa, Asia and South America, and covers the period 1980–2016. We consider bilateral aid flows into three sectors, namely education, health and agriculture, and find that among the three types of aid, education aid is more effective for aid-receiving countries. The effect is conditional on the current level of institutional quality and varies substantially across regions. While education aid is more effective in South America, health aid is more effective in Asia and agricultural aid is more effective in Africa. As the level of institutional quality improves, the gap between the marginal effect of education, health and agricultural aids widen. Our findings have strong policy implication for donor countries and international aid organisations, which shows that it is more desirable to shift aid flows towards the education sector as the level of institutional quality improves.     

AGRICULTURAL COOPERATIVES AND RURAL LIVELIHOODS: EVIDENCE FROM ETHIOPIA

ABSTRACT: Agricultural cooperatives are important rural organizations supporting livelihood development and poverty reduction. In recognition of such roles of cooperatives, Ethiopia showed a renewed interest in recent years in promoting cooperative sector development. However, there is lack of a wider and systematic analysis to produce sufficient empirical evidence on the livelihood development and poverty reduction impacts of cooperatives in the country. Using a matching technique on rural household income, saving, agricultural input expenditure and asset accumulation as indicator variables, this paper evaluates the livelihood impact of agricultural cooperatives in Sidama zone, Ethiopia. The finding shows that cooperatives improved the livelihoods of service user farmers through impacting better income, more savings and reduced input costs. In view of such evidence, further promotion, deepening and supporting of agricultural cooperatives is recommended.     

内生农业技术进步的二元经济增长模型——对“东亚奇迹”和中国经济的再解释

通过吸收内生增长理论的思想 ,修正外生农业技术进步的假设 ,本文提出了一个内生农业技术进步的二元经济增长模型 ,并以此对倍受瞩目也颇多争议的“东亚奇迹”及中国经济 ,从二元经济结构转换的角度进行了分析。本文认为 ,“东亚奇迹”是传统农业劳动力不断转向现代非农业部门的结果 ;是现代部门以资本反哺传统部门 ,推动农业技术进步 ,促进劳动力转移的结果 ;也是现代部门均衡发展 ,吸纳剩余劳动力 ,加速结构转换的结果。因此 ,虽然非农部门的全要素生产率提高不够显著 ,但劳动力结构转换仍然推动经济实现了持久的高速增长。     

STRUCTURAL CHANGE THROUGH PUBLIC EDUCATION EXPENDITURE: EVIDENCE FROM CHINA

Under China's hukou system, I analyze the relationship between public education expenditure and structural change as measured by labor transfer from the agricultural to the industrial sector. I construct a two‐sector general equilibrium model, which shows that in the short term, public education expenditure crowds out industrial capital accumulation and temporarily hinders structural change, but in the long term, public education expenditure permanently reduces rural residents' education costs. An inverted U‐shape relationship implied by the empirical evidence indicates that China's current public education expenditure is far from optimal, suggesting that China should increase it, especially for rural residents.

Job-search and foreign capital inflow — A three-sector general equilibrium analysis

The purpose of this paper is to extend the Fields' (1989) multi-sector job-search model in a three-sector general equilibrium framework by introducing international trade and capital as input. The three sectors are the rural sector, the urban informal sector and the urban formal sector. The rural sector and the urban informal sector use one type of mobile capital while the urban formal sector uses a sector-specific capital. We find that the effects of an inflow of foreign capital in the urban formal sector on unemployment and social welfare crucially hinge on the relative factor intensities of the rural sector and the urban informal sector. We show that there is a possibility of trade-off between the government's twin objectives of improvement in social welfare and mitigation of the urban unemployment problem. These results are extremely crucial from the view point of policymaking in an unemployment plagued, low-income developing economy.     

The effects of education on agricultural productivity under traditional and improved technology in northern Nigeria: an endogenous switching regression analysis

This paper estimates a more efficient version of an endogenous switching regression model to examine the effects of farmer education—schooling and extension contact—on cowpea production under traditional and improved technology in northern Nigeria. The results revealed significant productivity-enhancing effects of schooling and extension contact only under improved technology. Factors that promote technology adoption will thus indirectly raise the marginal contributions of farmer education; these include schooling, participatory technology evaluation, improved seed supply, and market access. The results demonstrate that schooling not only enhances agricultural productivity following technology adoption but also promotes adoption itself.     

个体、部门与家庭特征对城镇人力资本的影响

文章运用CGSS(2003)微观调查数据研究了教育等级、部门、经验、地区以及家庭等因素对中国城镇人力资本形成的影响作用.研究结果表明,一方面2003年中国城镇教育收益率为8.3%,教育边际收益率递减依然没有发生,东部地区人力资本回报明显高于中、西部地区,劳动力转移会提高人力资本回报;另一方面与以往多数研究不同,就业的部门差异对人力资本的影响不显著,但家庭尤其是父母的人力资本存量对子女人力资本的形成有显著稳定的正向影响作用.
