我国中药产业国际竞争力提升策略研究

中医药作为中华传统文化的载体,兼具人文交流与服务贸易的双重功能,对于提升我国在"一带一路"合作中的软实力及发展服务贸易新业态具有独特作用。本文从中药标准化生产能力、国际市场份额、国际专利水平以及研发投入等角度综合阐述我国中药产业国际竞争力现状。分析表明,创新理念缺乏、制度保障不强以及管理水平不高是制约我国中药产业国际化的主要因素。提升我国中药产业国际竞争力,要制定中药产业国际化战略、增强在世界中医药标准与知识产权中的话语权、强化企业跨国经营能力并加强国际化人才培养。     

基于库诺特竞争模型的技术创新投资可行域分析

运用完全信息静态博弈的库诺特模型对寡头企业的技术创新投资进行了分析,得出如下结论:①寡头企业通过技术创新投资可以提高企业的商品市场占有份额、降低产品价格,并使企业赚取更多利润;②两家寡头企业同时进行技术创新比只有一家企业进行技术创新给社会及消费者带来更大利益;③合谋垄断条件下,进行技术创新后社会总供给增加、产品出清价格降低,技术创新给消费者带来更大利益;④两家寡头企业联合进行技术创新,相对于一家企业独立创新中,只有技术创新的固定投入使得创新产品的单位成本降低的幅度满足一定条件时,联合创新的产品价格才会降低,产品的总产量增加,产品总利润提高。基于上述结论得出技术创新投资的可行域。     

企业信息化人才可持续发展机制浅探

在全面迈进信息时代的21世纪,企业的生产经营能否取得令人瞩目的成效,关键取决于企业攫取信息的速度、深度以及由此而做出的正确响应.因此,系统掌握信息技术和技能的信息化人才的培养,尤其是企业信息化人才可持续发展机制的建立,则成为了企业发展的关键要素.本研究基于调研统计和回归分析,说明了信息化人才是企业不可或缺的关键资源,同时也是最短缺的资源,基于此提出了企业信息化人才可持续发展策略.     

On Gravity,Specialization and Intra‐industry Trade

Contrary to the popular belief, specialization is not necessary for gravity equations. This paper shows that the simple gravity equation holds if and only if the market share of an exporting country is constant across all importing countries. Specialization is just one special case satisfying this condition. The constant‐share condition can hold in a variety of situations where multiple producers compete with a homogeneous good. Further, this paper shows that the ratio of bilateral trade to the product of partner incomes is increasing in the extent of specialization and in the intensity of intra‐industry trade. Since the relationship is not model‐specific, the correlations among these variables do not support any specific model.     

A DYNAMIC ANALYSIS OF COOPERATIVE RESEARCH IN THE SEMICONDUCTOR INDUSTRY*

In this article I construct a dynamic oligopoly model of research joint ventures (RJVs) where firms, investing to improve product quality, fully share the rewards of research success. RJVs benefit firms by eliminating duplicative research efforts, but firms also give up the possibility of becoming a solo innovator. Consumers benefit from lower prices, but may have to wait longer for new products to arrive. I show that RJVs are welfare enhancing by quantitatively evaluating these trade‐offs with data from the semiconductor industry. I also analyze how changes in product market competition affect research cooperation.

不同配筋率的钢筋混凝土阻尼性能的实验研究

混凝土的阻尼功能对于提高结构稳定性、安全性和耐久性以及防震减灾等具有重要意义。本文通过试验模态分析法对不同配筋率的钢筋混凝土梁在其各阶固有频率下的阻尼性能进行了研究,结果表明随着配筋率的提高,钢筋混凝土构件的阻尼比是不断减小的。研究构件在自由振动下动态特性对于混凝土结构抗震设计有参考价值。

Empirical research on time-varying characteristics and efficiency of the Chinese economy and monetary policy: evidence from the MI-TVP-VAR model

Based on the general time-varying parameter vector autoregressive model and data mining technology, this study proposes a new extension mixed innovation time-varying parameter stochastic volatility vector autoregressive model and investigates time-varying characteristics and efficiencies of different shock effects on China’s monetary policy towards inflation and GDP. Using sample monthly data for 1979–2014, we utilize typical time points to illustrate the mechanisms between different economic variables via the Markov Chain Monte Carlo method and impulse response function. The empirical results show that the monetary transmission mechanism in China can be effective in the real economy, but with delay and efficiency leakage. The average delay and maximum efficiency can be measured through the MI model, which can capture accurate information of economic variables, effectively improving the precision of macroeconomic regulation and control. Meanwhile, the difference between the impacts of different channels is obvious; while the impact of interest rates is not significant, the impact of stock market is significant. The action mechanism between GDP and the inflation rate undergoes a gradual structural change, evidently displaying time-varying characteristics and a gradually weakening impact over time.
