DEA的林业上市公司投资效率探究

投资决策与投资效率是企业价值提升的重要保障,投资效率测度是管理者制定科学投资决策和发展战略的重要依据。基于DEA模型的理论价值与实践优势,吉林森工、永安林业等八个林业上市公司投资效率的实证结果表明:第一,林业上市公司投资效率与规模效益呈现一定的时间特征;第二,由于技术革新、管理体制完善、财务管理模式优化、现代林业产业发展理念等,林业上市公司投资效率表现为短期的DEA非有效性与规模效益递增;第三,由于盲目多元投资、原材料成本、管理成本或其他风险等,其表现为短期的DEA非有效性与规模效益递减。

运输物流上市公司经营绩效评价——基于数据包络分析

近年来,中国物流业得到了突飞猛进的发展,成为推动我国经济成长的新亮点。但运作效率较低、成本较高等因素制约着物流业的发展。本文以2011年中国运输物流上市公司的相关数据为样本,利用数据包络分析法,从投入产出角度对其经营绩效进行了分析评价。结果表明,我国运输物流企业的经营绩效已处于相对较高的水平,2011年的综合效率平均得分达到0.901,纯技术效率平均得分为0.942,规模效率平均得分为0.956;但从总体来看,DEA有效率偏低,2011年度38家运输物流上市公司(剔除数据不完备的3家)中仅有14家达到DEA有效,占总体的比重为36.84%。最后根据DEA分析的结论,本文提出通过采取降低成本费用、精简员工、控制企业规模等措施来提高公司经营绩效和实现资源配置最优的政策建议。

探索提高基层林业统计质量的方法

林业生产在国民经济发展中占有重要的地位,林业生产内容繁多,有营林、森林采伐、木材加工等生产单位,又有从事林产品流通的林产品贸易公司、林业物资供应站,还有从事部门经济和行政管理的各种科学研究和社会服务机构。因此,基层林业统计工作是更为繁杂的一项工作,尤其在基层林业企业单位,统计工作任务繁重、条件艰苦、力量薄弱,统计质量等方面存在问题也比较多。     

我国房地产税制的现状及改革构想

房地产税制是维护房地产市场公平竞争，实现国家对房地产业宏观调控的有力杠杆。然而，我国现行的房地产税制却存在税费不分、税制不统一、税制结构不合理等诸多问题。严重影响了其对房地产业应有的宏观调控作用。因此，适时地推进房地产税制的改革应是当务之急，应统一内外税制，合理界定税费的范围，建立统一、规范、合理的房地产税收体系。

Public participation in forestry in Turkey

Recently public participation in forestry has been seriously considered in Turkey. Participation is however quite a challenge for a country with a long tradition of top-down management and a strong bottom-up dependence on public provisioning. In such a setting, it may not be surprising that the experiences with public participation in forestry in Turkey are mixed. There are some positive initiatives like the creation of farmer's cooperatives and NGOs, but their role is quite limited and small of scale. This paper is bringing together different views based on existing studies in Turkish related to Turkey's experience with implementing public participation in forestry.     

Is wealth found in the soil or in the brain? Investing in farm people in Malawi

Should a typical developing country invest more in agriculture or education? At what stage of development is it optimal to invest more in each of these sectors? These are important questions that governments of developing countries grapple with when designing investment plans. In this paper, I propose a soil–human capital conceptual framework of development and use it to explain estimates of agricultural returns to schooling in Malawi. I use panel survey data for Malawi and rely on the exogenous education policy changes and spatial variation in access to schooling to identify effects of schooling on agricultural incomes. In addition, I correct for selection into income activities within a panel data and instrumental variables estimation framework. I find annual agricultural returns to schooling in Malawi of 3%–4% after correcting for selection and unobserved heterogeneity and 7% in the uncorrected specifications. I also find consistently higher returns to schooling in the nonagricultural sector for those not living in the village of birth and higher returns in the agricultural sector for those living in the village of birth. Given the size of the farm sector, wealth in Malawi is still in the soil, but that future growth in wealth depends on human capital investments.

Inter-enterprise arrears in economies in transition

In the context of economies in transition, the paper argues that an excessive liquidity squeeze could throw the economy into a persistent state of low economic activity. In such bad equilibrium, enterprise transactions become largely demonetized, with a chain of arrears, a form of involuntary credit, spreading over the entire system. The empirical analysis of the Romanian experience seems to support the view advanced in the paper.     

Agricultural Roots in Intergenerational Transfers in China

Economists have been interested in the motivations of intergenerational transfers, for different motivations affect the effectiveness of anti-poverty public transfers. However, one’s motivation is largely shaped by culture and social conventions. This paper sheds light on the influence of rice cultivation in intergenerational transfers in China. This is also the first time that economists consider cultural factors in the study of intergenerational transfers. Cultivating rice requires elaborate irrigation systems and large amounts of labor input so that rice farmers have to cooperate extensively with their neighbors, which has gradually shaped people’s value to be more inter-dependent. Based on micro-level data from CHARLS and sub-national rice data from China, our empirical results show strong evidence that individuals from rice regions are more likely to provide economic support for their parents. A one-percentage point increase in the share of rice in the total grain planting area will raise transfer incidence by 0.2–0.4 percentage points, and rice region residents transfer on average 300–400 yuan more in 2011 and about 1,000 yuan more in 2013 to their parents than those from wheat regions. Meanwhile they are more inclined to rely on their adult children for elderly support. Urban citizens are less affected. Using instrumental variable estimation, we are able to prove the effect is causal. With future continued deepening of population aging in China, relying on children for old age support may become more and more unrealistic, the government needs to coordinate the relationship between public transfer and private transfer to ensure the quality of life for the elderly.     

2010年黑龙江省宏观经济展望

受世界金融危机的影响,从2008年下半年起黑龙江省经济持续走低,2009年一季度跌入谷底。2009年前三季度,在国家扩大内需的政策刺激下,黑龙江省经济企稳回升,但经济运行中还存在出口下滑、物价水平较低等问题,经济下行的压力仍然存在,经济持续回升的基础尚待巩固。展望2010年,国家将继续实施积极的财政政策和适度宽松的货币政策,随着政策效应的逐步释放,内需对经济的拉动作用仍将十分强劲,另外,随着世界经济的复苏,黑龙江省外贸形势也将逐渐好转,在＂投资、消费、出口＂这三驾马车的共同作用下,2010年黑龙江省经济将步入全面复苏通道。     

Gender Differences in Time-Poverty in Rural Mozambique

Based on time-use data from a 2013 primary household survey, this study examines the nature and extent of time-poverty experienced by men and women in peasant households in Mozambique. The main findings indicate that while women's labor allocation to economic activities is comparable to that of men, household chores and care work are almost entirely women's responsibility. The heavy burden of responsibilities leave women significantly time-poorer compared to men. Women's time-poverty worsens when the burden of simultaneous care work is taken into account. In addition, due to multitasking, the work tends to be more taxing. The examination of determinants of time-poverty shows that common measures of individual economic power, such as assets and education, do not necessarily affect the time-poverty faced by women.     

Trade-offs in sulfur emission trading in Europe

How to implement emission trading is one question in the current negotiations on a new sulfur protocol in Europe. Whereas the current protocol stipulates a 30 percent uniform reduction, national emission ceilings included in the proposed new protocol imply differentiated reductions. In addition, emission and fuel standards are proposed. This paper examines the costs and environmental impacts of emission trading. Emission trading combined with regulations is a new element in the paper. Calculations using the RAINS (Regional Acidification INformation and Simulation) model suggest that overlaying emission trading on regulations not only reduces the cost savings but has beneficial impacts as well: ecosystem protection is not changed and significant decreases in environmental benefits for countries are largely avoided. Emission trading can also be used to decrease emissions and increase ecosystem protection. If combined with existing legislation, emission trading minimizes losses in expected environmental benefits for some countries, and most countries gain. However, the initial distribution of emission ceilings has to be used so that some countries are not confronted with higher costs. Trade-offs appear to exist between the use of emission trading to achieve cost savings on the one hand, and ecosystem protection and distributional equity on the other.
