林权流转主导模式与制度创新

顶层制度上受相似的基本的社会条件制约,集体林权流转进而也期待形成"三权分离"的经营格局。但是,由林地、林权本身特性决定的物权式流转的主导模式,将导致林农承包权的退出。基此,通过经验与规范实证的结合分析,诸如林下经营权及其流转等有关制度性措施、实践的意义与价值及其局限性可被清晰认知,进而制度供给仍有不足也被问题化。欲有所作为并能有效应对,则林权流转在普通的方式之外,可考虑引入典权制度。而典权是一种均衡的制度安排,兼顾了社会实质正义。     

Transdisciplinarity in land use science – A review of concepts,empirical findings and current practices

In the search for solutions to complex real-world problems, the benefits of transdisciplinary research (TDR) have been widely heralded. Land use science appears to be a designated field for TDR. However, to date, the additional expenses of TDR are accompanied by a so far not proved added value, and empirical findings are claimed to be scarce and dispersed over several disciplines and case studies.We reviewed 299 articles obtained from a structured literature search to (1) investigate the current differences between theory and practice, (2) identify empirical findings, and (3) ascertain the contributions of TDR to promoting sustainable land use management.Our results demonstrate that, in spite of an increasing conceptual consistency in the theoretical discussion of TDR, the implementation of TDR remains a substantial challenge, in part because of the gap between theory and practice. In addition, research on TDR is science and process centred. The benefits of TDR in addressing real-world problems within the field of land use remain unproven.     

农地征收、农地流转与农民人均收入——基于空间滞后模型估计

通过考虑空间溢出性,构建固定效应空间滞后模型,并利用2009—2014年省级面板数据研究农地征收、农地流转对农民人均收入的影响。研究发现:农地征收面积每提高1%,农民人均收入将会降低0.039%,表明农地征收会降低农民人均收入;农地流转面积每提高1%,农民人均收入将会提高0.011%,表明农地流转有利于农民收入的提高。因此农地在征收过程中,应提高土地补偿费及农民就业能力,保障农民利益不受损,同时积极稳妥推进农地有序流转,形成规模经营。     

基于可变模糊方法的乡村土地旅游化流转风险评价的集对分析

为解决乡村土地旅游化流转风险评价问题,构建了包含粮食安全受威胁程度、收益分配不公平程度、土地利用结构失衡程度、乡村生态破坏程度以及乡村特色消失程度的乡村土地旅游化流转风险评价指标体系,提出乡村土地旅游化流转风险评价的集对分析—可变模糊模型与方法。首先,基于集对模糊联系度构造可变模糊集理论的相对差异度,进而建立集对分析—可变模糊综合评价模型;然后,结合风险分级特征值运用二元语义方法确定乡村土地旅游化流转风险级别;最后,以泉州市乡村旅游目的地为例进行了实例计算。研究结果表明,所建立的集对分析—可变模糊评价模型与方法不但能够定量辨别乡村旅游地土地旅游化流转的风险等级,而且能够区分同一风险等级下的不同风险大小。     

基于CVM方法的福州国家森林公园游憩价值评价

基于CVM方法对福州国家森林公园的游憩价值进行评价,调查结果得出:2015年福州国家森林公园的游憩价值为2.164亿元。游客对公园的满意度和旅游次数与游客的支付意愿呈显著正相关(p0.05),游客的家庭人口数(p0.01)、月收入(p0.01)和职称(p0.05)与游客的WTP值呈显著正相关。基于研究,景区应在生态环境、服务设施和质量上进一步挖掘公园潜在的游憩价值,并在游客森林游憩过程中,普及生态环境知识和宣传教育,提高游客的生态保护意识。     

农户收入分化对林地流入与流出意愿影响研究

以辽宁省409户样本农户问卷调查为基础,采用描述性统计分析农户收入分化在农户年龄层次、受教育程度、家庭劳动力数量等方面的差异化特征,并运用二元Logistic回归模型分别讨论收入水平分化、收入结构分化、二者交互项对农户林地流转综合意愿、流入意愿、流出意愿的差异化影响。结果表明:农户收入水平分化对林地综合流转意愿、林地流入意愿具有显著正向影响;农户收入结构分化对农户林地流出意愿具有显著正向影响;农户收入水平分化与结构分化交互项对农户林地综合流转意愿、林地流出意愿具有显著正向影响。因此,需要关注农户收入分化因素;做好收入分化因素的有效识别;充分认识收入分化因素对农户林地流入与流出意愿的差异影响;把握分化特征,有针对性提高林地流转意愿。     

Market-based grazing land transfers and customary institutions in the management of rangelands: Two case studies on the Qinghai-Tibetan Plateau

Beginning in the early 1990’s, grazing lands once held in common were contracted to individual households in the rangeland regions of China. The resulting fragmentation of rangelands has led to ecological and social problems. As China seeks to address intractable poverty and rangeland degradation, attention has turned to rental, or transfer, of contracted grazing land as a market-based approach to re-aggregating grazing land into larger units that support economies of scale. However, given that many pastoral regions still maintain community customary institutions, what the relationship between market mechanisms and local customary institutions should be in rangeland management needs further analysis. This paper applies comparative case studies of two types of relationships between market mechanisms and customary institutions: (1) market mechanisms that replace customary institutions in the case of Axi village, and (2) market mechanisms that are embedded within customary institutions in Xiareer village. This allows contrast of the impacts of differing approaches on livelihoods, livestock production, and wealth differentiation among pastoral households. We found that there is a higher level of livestock mortality, lower livestock productivity, and higher livestock production cost in Axi Village compared to Xiareer Village. In addition, household asset levels are higher and there is less income differentiation in Xiareer Village. It is concluded that embedding market mechanisms within customary institutions has had notable benefits for the herders of Xiareer Village, because it is a better fit to the coupled pastoral social-ecological system. Based on these findings, we argue that in pastoral communities where the rangeland transfer system for contracted grazing land has not yet been implemented, it is critical to reconsider China’s current policy approach to pay greater attention to the innovative management systems being developed in local regions. Instead of considering market-based approaches as oppositional to traditional institutions, options that derive from the interaction of market-based and customary institutions should be considered.     

Why do companies transfer the trading compartment of their common stocks

We analyze the motives and determinants of voluntarily stock exchange section switching on the NYSE Euronext. By strategically deciding trading-section transfer when it is beneficial, managers expect to reduce their liquidity and invisibility costs, cost of capital, or their listing costs. We show that managers decide to change the trading compartment of their common stocks based on various factors including firm's size, liquidity level, debt ratio, and expected growth opportunities. Firms that move voluntarily from a less or non regulated compartments to a more regulated one are likely to have transferred to increase their credibility, improve their stocks’ liquidity, re-balance their leverage, and to finance their growth opportunities. Whereas those that move their common stocks toward a less-regulated compartments do it mainly for costs saving reasons.     

陕西省农地经营权流转服务体系建设浅析

2011年《陕西省人民政府关于促进农村土地承包经营权流转的指导意见》发布以来,陕西省农地经营权流转发展迅速,农业生产效益得到明显提高;但仍存在土地产权不明晰、农地经营权流转市场不成熟、农地经营权流转法律法规不健全等问题,严重限制农地经营权流转的速度与范围。文章采取实地查勘、问卷调查、走访农户、搜集数据及逻辑分析等方法,针对陕西省农地经营权流转的现状、问题、成因进行实地调研,并提出加强陕西省农地经营权流转服务体系建设的合理化建议:(1)通过土地确权、规范农地经营权流转流程,提高农地经营权流转效率;(2)通过发展现代农业电商平台、保险、智库、创客空间,提高农业收益。
