中国粮食生产功能区农业环境效率及其改进程度——基于FDH方法的经济和人力资本空间异质性检验

基于自由处置赫尔(FDH)技术方法,综合考虑环境因素和社会经济空间异质性,运用SFA技术构建农业环境效率测算模型,考察了2001—2019年我国3大粮食生产功能区农业环境效率及其改进状况。结果显示,经济和人力资本空间溢出效应下农业环境效率均值分别为0.846和0.843,各省(区)农业环境效率呈现显著的正向空间相关性,普遍能够从经济和人力资本空间溢出效应中获得1%~20%不等的改进程度,而又以经济空间溢出效应作用更强;在经济和人力资本空间溢出效应作用下,主产区和平衡区虽然获得较高的农业环境效率值,但效率改进程度仅维持在2%左右,而主销区虽然农业环境效率较低,却能够获得超过20%水平的效率改进。然而,各功能区无论是农业环境效率值还是效率改进程度,在空间上存在显著的差异且在时间上呈现明显下降趋势。     

品牌延伸会影响品牌个性吗？——反馈效应的视角

品牌个性和品牌延伸都是品牌管理的重要内容，二者相互影响，过去的研究着重于品牌个性对品牌延伸的影响，但品牌延伸亦会影响品牌个性发展。选取我国医药行业老字号品牌云南白药作为研究对象，首先对云南白药的品牌个性进行探索性研究，通过四个定性研究确定云南白药品牌个性的项目词汇库，然后通过问卷调查获得的353份样本进行探索性因子分析，确定了云南白药的品牌个性的三个品牌个性维度，即经典真诚、可靠安全、独特神秘。在此基础上，针对云南白药向日化产品的品牌延伸如何影响其品牌个性提出理论假设，通过问卷调查获取205份样本，应用回归分析对假设进行检验，发现品牌延伸的两个维度情感延伸和功能延伸对品牌个性都有显著的正向影响，但功能延伸对品牌个性的正向影响更加显著，而且功能延伸和情感延伸对品牌个性各个维度的影响效果不一。     

全民所有自然资源资产保护和使用规划的功能定位与编制路径

研究目的：解析全民所有自然资源资产保护和使用规划的性质、定位、与相关规划的衔接关系、编制路径与主要内容。研究方法：基于产权理论、自然资源价值理论和资产规划理论的归纳演绎。研究结果：自然资源资产保护和使用规划兼具民事和行政属性，基于所有权和监管权的规划内容应有差异。规划定位是包含了资产选择搭配规划、资产运营规划和资产管理工作规划的自然资源资产权益管理顶层设计，是国土空间用途管制下的国有资产运营规划。自然资源资产规划与国土空间规划相互支撑、补充。研究结论：自然资源资产保护和使用方案应按照“分区、分类、分级”的技术思路编制，规划内容应包含资产管理制度建设和资产保护使用方案两项主要构成。     

Predictable forward performance processes: Infrequent evaluation and applications to human-machine interactions

We study discrete-time predictable forward processes when trading times do not coincide with performance evaluation times in a binomial tree model for the financial market. The key step in the construction of these processes is to solve a linear functional equation of higher order associated with the inverse problem driving the evolution of the predictable forward process. We provide sufficient conditions for the existence and uniqueness and an explicit construction of the predictable forward process under these conditions. Furthermore, we find that these processes are inherently myopic in the sense that optimal strategies do not make use of future model parameters even if these are known. Finally, we argue that predictable forward preferences are a viable framework to model human-machine interactions occurring in automated trading or robo-advising. For both applications, we determine an optimal interaction schedule of a human agent interacting infrequently with a machine that is in charge of trading.     

The Evolution of Income Composition Inequality in Italy, 1989–2016

We study the evolution of inequality in income composition in terms of capital and labor income in Italy between 1989 and 2016. We document a rise in the share of capital income accruing to the bottom of the distribution, while the top of the distribution increases its share of labor income. This implies a falling degree of income composition inequality in the period considered and a weaker relationship between the functional and personal distribution of income in Italy. This result is robust to various specifications of self-employment income; nonetheless, it hinges crucially on the treatment of rental incomes. While the dynamics of imputed rents has brought about a more equitable distribution of capital incomes across the income distribution, that of actual rents has led to higher concentration of capital incomes at the top in the decade preceding the outbreak of the financial crisis. Finally, we conceptualize a rule of thumb for policy makers seeking to reduce income inequality in the long run.
