R&D/产品问题模型对于价格竞争的包容性探讨——价格竞争也是一种数量竞争

R&D/产品问题的文献,都无一例外地在模型中采用了数量竞争(产量作为决策变量)的形式;而现实中市场往往以产品的价格作为第一操作变量进行竞争,或采取更为剧烈的“价格战”。从价格竞争的Cournot均衡模型出发,对模型中的变量进行替换得到产量竞争模型的形式,在这一变换中,并不改变竞争各方非对称的产品替代性和竞争优势,表明这种形式上的转化并没有使原来的产业特性在转变中发生相对改变。进一步对模型中的产品替代性进行讨论,可以说明Bertrand式的价格竞争也可以映射一种数量竞争。     

专利保护和加计扣除政策能够促进私人农业技术创新么？

摘要：专利保护和加计扣除政策是政府保护和激励私人技术创新的重要手段。本文利用2005-2015年间77家农业上市公司公开数据，研究了专利保护和加计扣除政策对私人农业研发投入与研发投入强度的影响。结果表明，专利保护政策并未促进私人农业研发投入或者提高私人研发投入强度，而加计扣除政策则显著提高了私人的研发投入和研发投入强度。通过设置专利保护和加计扣除政策的交互项，发现专利保护的增强削弱了加计扣除政策的溢入效应。本文结论验证了已有的部分研究结论，建议进一步完善专利保护政策，加强加计扣除政策的实施广度和强度，推动国家创新体系建设。     

Relative efficiency of R&D activities: A cross-country study accounting for environmental factors in the DEA approach

This paper applies the production framework associated with the data envelopment analysis (DEA) method to evaluate the relative efficiency of R&D activities across countries. R&D capital stocks and manpower are treated as inputs while patents and academic publications are considered as outputs. A three-stage approach, which involves using DEA for evaluating efficiency and using Tobit regressions for controlling the external environment, is applied to 30 countries in recent years. The results show that less than one-half of the countries are fully efficient in R&D activities and that more than two-thirds are at the stage of increasing returns to scale. Most countries have a more significant advantage in producing SCI cum EI publications than in generating patents.     

基于纵稿控制框架的上游企业R＆D研究

本文在纵向控制框架内研究上游企业R&D。R&D活动降低中间产品转移价格 ,增加最终产品供给数量 ,纵向兼并、全面一体化增加R&D和最终产品供给数量 ,但都比社会福利最大化时小 ;R&D边际成本增加减少R&D和最终产品供给数量。政府应当补贴R&D ,鼓励纵向兼并和全面一体化 ,避免横向兼并

Can creative destruction be destroyed? Military IR&D and destruction along the value-added chain

We elaborate a supply chain innovation matrix that can be applied to both commercial and military supply chains. By shifting the analysis from a focal firm to industry structure, we argue that the market structure of the entire supply chain functions as a major moderating variable in determining both the timing and adoption of innovations, both for commercial and military markets. We extend work on supply chain resource dependency by drawing a distinction between market-structure-induced resource dependency and supplier over-reliance on a customer in a competitive market. This has policy implications for the organization of military industrial research and development (IR&D). Joint service research and development (Jointness) will certainly bring about innovation, but it will be incremental, reinforcing established military hierarchies. Policy makers may need to add this probable consequence when comparing Jointness and inter-service rivalry. The cost savings inherent in Jointness may unwittingly sustain a military force unready for fighting the next war.

R＆D资本化下高新技术企业价值评估研究

本文在阐述R＆D支出是决定高新技术企业价值的主要因素之一，并在描述各国有关R＆D的会计处理原则的基础上，以“自由现金流量”模型中的主要变量：现金流量、资本回报率、预期增长率为评定指标，比较分析R＆D费用化和资本化下各评定指标的波动所导致的对企业价值增长的不同判断，最终为我国现行的R＆D支出会计处理原则提出改进建议。
