水库移民分享水电工程效益的制度逻辑、 实践困境及破解之道

水库移民分享水电工程效益旨在促成显性工程效益和隐性发展机遇实现跨地域、跨组织、跨主体的公平配置。 作为水库移民的应然权利,利益分享既符合公正补偿的制度逻辑,更彰显共商共建共赢的发展理念,但目前补偿救济色彩较重、市场导向偏弱,并存在后靠移民发展权利及机遇隐性被动减损、外迁移民脱嵌于迁出地及受益地发展红利、非农移民缺乏系统保障等实践困境,其原因在于水电工程综合效益量化难度大、参与主体关系地位不对等、执行管理机构人员配置短缺。 因此应健全水电工程效益分享协同管理机制,鼓励水电企业履行社会责任,优先助力贫困水库移民脱贫,灵活渐进地实现水库移民分享工程效益实践机制的稳步定型和有序推广。     

水信息披露、机构投资者异质性与企业价值——来自我国A股制造业上市公司的经验证据

以我国2011-2016年A股制造业上市公司为研究样本,本文采用面板回归模型实证检验了企业水信息披露对企业价值的影响以及异质机构投资者在二者关系中的调节作用。结果表明：目前企业水信息披露水平整体较低,其对企业价值有显著的负向影响;在该影响中,机构投资者整体有显著的正向调节作用,压力抵制型机构投资者有显著的负向调节作用,而压力敏感型机构投资者无显著的调节作用。     

农地制度变迁的机理与合约分析：生产队制和家庭联产承包责任制

家庭联产承包责任制在农业生产上的高能激励自农地制度变革以来一直被学界所推崇,但这并不意味着生产队制的低效率。为此,在否定以生产队制低效率作为农地制度变迁的解释的基础上,从发展战略转换、制度安排缺陷、农民信念及其他方面尝试性地探讨了推动生产队制向家庭联产承包责任制变迁的内在原因,并且从生产责任制形式、土地分配方式、期限结构等方面详细阐述了家庭联产承包责任制向农业产出最大化演化的过程。相应地,伴随着农地制度变迁而来的是签约主体以及合约结构的变动,因此,从合约的角度进一步研究了生产队制与家庭联产承包责任制在合约实施和劳动监督与计量上的差别,以及作为二者共同之处的合约模糊性特征,并在此基础上对家庭联产承包责任制下税费合约的性质与形式进行了具体的分析。     

动词隐含因果性和语篇话题性对回指选择的影响

动词隐含因果性和语篇话题性是制约回指选择的重要因素,但两者对回指选择的影响机制及交互作用仍不明确。语篇生成续写实验表明,动词隐含因果性确实会影响到后续指称对象的选择,并在原因类联结关系中得到加强;当动词语义倾向回指的对象为新引入的实体,而非语篇话题时,其回指倾向最显著。这说明基于给定语境生成语篇的过程遵循省力原则,但与语篇话题性相比,动词隐含因果性对回指倾向的制约更具刚性。     

研发部门体制改革与企业创新行为——以A股制造业上市公司为例

结合沪深A股制造业上市公司年报数据,构建Tobit回归模型对企业研发行为进行影响因素分析和稳健性检验。结论发现,研发强度与企业规模、大股东持股比例、经营年限负相关,但与技术人员人数占比正相关;此外,销售毛利率、存货周转率、现金比率以及市销率、市净率等指标也明显左右着企业创新积极性的发挥。为此旨在透过研发部门体制改革推动企业创新发展,建议由传统龙头企业拆分设立研发型子公司,对新兴初创企业引入战略投资者;鼓励企业将生产、销售业务逐步外包,探索建立多元化内源性融资渠道;试点成立创新型创投、私募等专项基金,制定针对性财税政策扶持等。     

关于如何完善土地流转的制度探讨---基于日本农地中间管理制度的分析与启示

土地流转是实现农业现代化的基础条件之一,但是,实现土地有序流转需要建立完善的制度体系。日本近年实施的农地中间管理制度旨在通过建立农地中间管理机构(农地银行)及相应的流转机制和流转补贴制度,促进土地向农业承担主体集中,提高农业用地的利用效率和集约化程度,进而提高农业生产力。通过对该制度的细致总结和效果分析,认为中国的土地流转制度有必要以目标为导向,完善制度设计、细化政策措施、调整农业补贴并注重基层和农民参与。     

Danish and Norwegian hospital social workers’ cross-institutional work amidst inter-sectoral restructuring of health and social welfare

Starting in the 2000s, Denmark and Norway have undergone extensive restructuring of their health-related social benefit programmes, including how they are governed. Several reforms have sought to enhance inter-sectoral collaboration. Aiming at ensuring patients’ faster return to work, policy-makers have instituted economic incentives to both individuals and the health and welfare organisations who handle them. Through an institutional logics approach, this paper explores how hospital social workers in these countries are experiencing these changes. The ‘social’ part of post-treatment care and rehabilitation receives more attention in the Norwegian institutional set-up than in the Danish, and whilst challenges are experienced in both countries, in group interviews Danish social workers in particular express concerns about the implications of the accelerated return-to-work focus. In both countries, they report increasing difficulties in ‘making their way through’ the state-municipal bureaucracy. However, by drawing on the formal health knowledge derived from medical settings and the symbolic capital it bestows on them, they often manage to negotiate the work-and-welfare services, thereby transforming the social context for the patients.     

Points System:An Universal Beneficial System with Multiple Objectives of Reform on Household Registration System

Reform of China's Household Registration system(HRS) has been entering a new stage and deserves us to research.The paper argues that reform of HRS should have multiple objectives.It examines various local efforts and practices of the reform and claims that the point system is one of the most feasible alternative systems for the HRS that can fit those multiple reform objectives.The system could also be treated as the new institutional basic for public welfare provision and rights allocation,and a new governance means for population issues as well in China's transitional period.     

Books on probability ideas are reviewed

In this paper, semiparametric methods are applied to estimate multivariate volatility functions, using a residual approach as in [J. Fan and Q. Yao, Efficient estimation of conditional variance functions in stochastic regression, Biometrika 85 (1998), pp. 645–660; F.A. Ziegelmann, Nonparametric estimation of volatility functions: The local exponential estimator, Econometric Theory 18 (2002), pp. 985–991; F.A. Ziegelmann, A local linear least-absolute-deviations estimator of volatility, Comm. Statist. Simulation Comput. 37 (2008), pp. 1543–1564], among others. Our main goal here is two-fold: (1) describe and implement a number of semiparametric models, such as additive, single-index and (adaptive) functional-coefficient, in volatility estimation, all motivated as alternatives to deal with the curse of dimensionality present in fully nonparametric models; and (2) propose the use of a variation of the traditional cross-validation method to deal with model choice in the class of adaptive functional-coefficient models, choosing simultaneously the bandwidth, the number of covariates in the model and also the single-index smoothing variable. The modified cross-validation algorithm is able to tackle the computational burden caused by the model complexity, providing an important tool in semiparametric volatility estimation. We briefly discuss model identifiability when estimating volatility as well as nonnegativity of the resulting estimators. Furthermore, Monte Carlo simulations for several underlying generating models are implemented and applications to real data are provided.
