技术独董、经济政策不确定性与企业创新产出

创新产出是企业创新能力的直观体现,也是企业价值创造的源泉。以2008—2017年披露了专利授权信息的中国A股上市公司为样本,研究了独立董事技术专长对企业创新产出的影响。结果显示：（1）技术独立董事显著地促进了企业创新产出,且这种促进作用受到经济政策不确定性的负向调节;（2）技术独立董事是通过提高企业的创新投入来促进企业的创新产出的;（3）技术独立董事兼职席位与企业创新产出呈倒U型关系。根据上述研究结论,企业应当增加技术独立董事的引入并适当限制技术独立董事在其他企业兼职的行为,以充分发挥技术独立董事的创新驱动效应,提高企业创新产出。     

探究“新零销售”模式下影响销售量的相关因素

在新零销售模式的推动下,客户越来越倾向于消费个性化的商品。为了精准预测客户的消费需求,论文以单款单色产品为研究对象,通过建立多元回归分析的数学模型,来探究影响商品销售量的相关因素。经过分析发现,除了一些定性因素外,定量因素对销售量也产生了一定的影响,其中实际花费总金额、实际销售单价、库存数等定量因素对销售量的影响较大,且各个变量之间具有相关性,所以电商平台应特别关注这三个变量的影响。     

Open access,common property and scarcity rent in fisheries

Open access resources are frequently not managed efficiently, resulting in falling stock levels and a declining income for fishermen. In the late 1970's, the policy response to this problem was the implementation of 200-mile fishing zones, which enabled the European Union to formulate and implement the Common Fisheries Policy, aimed at (among other things) conservation and distribution of available stocks. In Germany, this shift from an open access regime towards a common property regime had favourable outcomes. The trend of falling prices was reversed. The conclusion was that intertemporal efficiency had increased as a result of (inter)governmental policy. Apparently, a wedge was formed between price and marginal harvesting costs, implying that scarcity rent had returned as a component of prices.     

Multiple Species Boreal Forests – What Faustmann Missed

Recent research in natural sciences shows that the dynamics in boreal forests are much more complex than what many models traditionally used in forestry economics reflect. This essay analyzes some challenges of accounting for such complexity. It shows that the optimal harvesting strategy for forest owners is history dependent and for some states of the forest, more than one strategy may be optimal.This paper confirms earlier literature on shallow lakes and coral reefs and shows that this kind of phenomena seem much more common than previously thought. They are valid for a wide range of ecosystems that cover large surfaces and they do not depend on the choice of some specific function to model the non-linearity. There are also indications that theses results could be obtained even for resources with concave growth if at least one species with non-linear growth affects their dynamics.     

The research of Chinese karst ecological hydrology

1. Introduction The area of carbonate rocks protruding through the soil level in China is 9.07*105km2. According to the area of carbonate rocks stratum protruding through the soil level, it is 2.06*106km2. With the buried carbonate rocks stratum of the different depths, its total area can reach 3.443*106km2, ap- proximately accounting for 1/3 of the national terri- torial area. Chinese carbonate rock is mainly distributed to the south of the latitude belt of Tianshan Mountain – Yinshan Moun…     

中国企业人力资本产权变革三次浪潮评析

人力资本股权化是现代企业产权制度变革的基本逻辑和大趋势.如何在实际操作层面解决"两权分离"悖论,不仅是现代公司制度运作和发展的主题,也是中国企业人力资本产权制度变革的逻辑起点、核心问题和主要矛盾.1992年以来,中国企业人力资本产权变革经历了三次浪潮.目前,对于中国企业来说,实现人力资本股权化、稚行股权激励计划,已经不是什么"理论"问题而是如何实际"行动"的问题.基于人力资本产权制度变革积极推行股权激励计划,是未来中国企业必然而明智的战略选择.     

Simulation driven inferences for multiply imputed longitudinal datasets*

In this article, we demonstrate by simulations that rich imputation models for incomplete longitudinal datasets produce more calibrated estimates in terms of reduced bias and higher coverage rates without duly deflating the efficiency. We argue that the use of supplementary variables that are thought to be potential causes or correlates of missingness or outcomes in the imputation process may lead to better inferential results in comparison to simpler imputation models. The liberal use of these variables is recommended as opposed to the conservative strategy.     

产品内贸易、技术创新与中国企业可持续发展

在科技革命和经济全球化的共同作用下，特别是随着FDI的增长和跨国公司的全球布点，传统意义上的以商品贸易为基础的国际分工正在被打破，国际分工逐步深入到企业内部，分工方式由产业间分工向产业内部产品分工和要素分工延伸。本文以当前新贸易现象为实践基础，以贸易分工理论为理论基础，初步构建产品内贸易的理论模型及其利益分配机制，从产品内分工视角分析产品内贸易模式对发展中国家贸易条件的影响，并认为中国企业应该在国际分工价值链上进行攀升，进行技术创新，提升在国际贸易中的地位，化比较优势为竞争优势，实现企业的可持续发展。     

论两种规模经济：专业规模经济和综合规模经济

当前国际上出现了一种“企业规模无关论”的新观点,与我国目前盛行的“唯规模经济论”截然相反。笔者以为,上述两论都失之片面,正确的理论是在承认的前提下,将规模经济分为两类:专业规模经济和综合规模经济。前者因专业化分工效应而扩大产销规模与市场份额;后者因企业(集团)内部协调成本小于市场交易成本而获得效应。随着市场发育和市场交易成本下降,拥有专业规模经济的企业集团,比之拥有综合规模经济的企业集团更能适应市场的变化与竞争。     

试论波特劳勒“综合激励模型”的应用

知识型员工是知识经济时代出现的新型工作群体熏他们是知识资本的掌握者,是企业最为宝贵的资源熏文章通过对波特劳勒综合激励模型理论的分析认为:对知识型员工的激励熏应建立在满足其较高层次需要的基础上熏在激励策略方面熏主要采取报酬激励、精神激励和工作激励等方式熏并且应根据知识型员工不同的特点,选择不同的激励方式组合,才能充分发挥知识型员工的工作积极性。
