How forestland size affects household profits from timber harvests: A case-study in China’s Southern collective forest area

To improve the economies of scale in forest management and reduce the fragmentation of forestland, the Chinese central government has implemented a collective forest tenure supplementary reform since 2008. This has included a series of policies for motivating transfer of forestlands use rights among households in the country’s Southern Collective Forest Area (SCFA). However, to date there is little evidence that large-scale forest owners can earn more profits from timber harvests than small-scale forest owners in the SCFA. Using data collected from household surveys in the three of the SCFA’s provinces in 2016, this paper examines the return to scale of forestland ownership for timber harvests in this region, and how the scale of forestland ownership affects households’ profits from timber harvests. The results show a constant return to scale in timber harvests in the case provinces in China’s SCFA, that forestland area makes the most important contribution to the output of timber harvests, and that fragmentation of forestland results in lower profits from timber harvests. It appears that a moderate scale of forestland ownership should be identified for increasing the profits from timber harvests. With the rapid urbanization throughout China, an increase in off-farm employment among rural household members has a negative impact on timber harvests in the region. We argue that policymakers should realize the importance of encouraging the forestland transfers and improve the concentration of forestlands in the next stage of forest tenure rights reform in China’s SCFA.     

中国农业竞争力提升视域下的小农户发展

目前我国农业发展面临一个急需破解的重大悖论：如何在发展小农户的基础上提升中国农业竞争力。论文提出中国特色农业竞争力具有三重内涵：以生产竞争力为基本要求，以安全竞争力为战略底线，以市场竞争力为主攻方向。小农户发展对于提升中国农业竞争力有重要作用，这体现于小农户发展有助于提升农业生产竞争力、安全竞争力和市场竞争力并推动提升机制之间联动。因此，提升中国农业竞争力必须促进小农户发展，并且小农户发展有提升农业竞争力的可能性，但当前小农户发展受到内外条件的约束。据此，本文提出以下政策建议：完善政府支持、发挥小农户主体作用、发展和推广农业科技和物质装备以及将小农户融入产业链。     

测绘项目应注意安全生产

随着国家经济建设的快速发展,测绘作为各建设项目的基础工作越发重要,因为从业门槛较低和从业人员队伍庞大,所以测绘安全生产显得尤为重要,如何进行安全生产管理,值得每个从业人员深思。     

安徽省税种结构变动的经济增长效应

根据安徽省1994年—2012年的样本数据,运用Cobb-Douglas生产函数理论模型,对税种结构变动与经济增长关系进行实证分析。结果表明:增值税占总税收比重的增加会降低人均生产总值,营业税、企业所得税、个人所得税、农业各税占总税收比重的增加会提高人均生产总值,资源税的经济效应不显著。因此,应该进一步优化现行税制结构:有序推进"营改增",完善中央与地方的税收分享体制;提高所得税的比重,增强其收入再分配作用;加快推进资源税改革,促进经济可持续发展;适度调节农业各税,培育农村大市场。     

Critical success factors for the sustainability of Kaizen event human resource outcomes: An empirical study

Kaizen events have been widely reported to produce positive change in business results and human resource outcomes. However, sustaining or improving upon the results of a Kaizen event over time can be difficult for many organizations and has received limited empirical research attention to date. This paper identifies the factors that most strongly influence the sustainability of work area employee attitudes and commitment to Kaizen events based on a field study of 65 events in eight manufacturing organizations. The findings also present guidelines for organizations and areas for future research.     

The reduction cost of nonperforming loan: evidence from China’s commercial bank

The nonperforming loans (NPLs) are co-generated by creating the profit in a bank, and this article build a joint production model to measure the reduction cost of nonperforming cost. By using a data set of China’s 13 commercial banks, the conclusions show that the reduction cost of NPLs is lower, which suggests that it is not a good choice for China’s commercial bank to hold the NPLs.     

上海人口郊区化与产业郊区化协同发展研究

上海市人口郊区化和产业郊区化发展的过程中,由于人口规划和城市基础设施建设、产业发展和城市之间缺少有效地协调机制,公共服务资源配置相对滞后,造成郊区新城人户分离、产城分离问题日益严重。通过对社会、经济、政策等相关因素的分析,鉴于郊区经济发展对人口的导入功能将进一步增强,郊区人口还将持续增加,从人口郊区化与产业郊区化协同发展的角度对产业发展、人才引进、公共资源配置等方面提出了建议。
