新疆对外贸易与经济发展相互关系研究

对外贸易是经济增长的“发动机”,许多国家和地区通过时外贸易来推动国家和地区经济发展。新疆对外贸易验证了与经济发展的互动关系,我区应大力发展对外贸易,带动经济增长。     

论生命视角下的教师教育

教育的起点是“人”的教育,教师的责任是教人做人。教育不仅要关注学生的生命成长,也需要关注教师的生命成长。在以往的教师教育中,我们过分注重教师的技能化培训,而忽视了教师生命的完善与发展。因此,要实现人的完整性,使之走向完美境界,就必须完善教师的生命价值,使其在帮助学生完整实现自己的同时也创造着属于教师自己的生命意义与自身价值。     

Boundary control of a linear distributed parameter bioprocess

This paper is concerned with boundary control of a linear distributed parameter bioprocess. Huang's result (Ann. Differential Equations 1(1) (1985) 43) on the spectrum determined growth assumption is applied to prove that the closed-loop system becomes exponentially stable under a certain condition with respect to the feedback gain. Moreover, it is shown that the decay rate of the open-loop system is given by letting the feedback gain tend to zero.     

Undesirable economic growth via agents’ self-protection against environmental degradation

Our model analyzes the effects of the interplay between environmental degradation and consumption choices on economic growth dynamics and on economic agents’ welfare. We show that if private goods can be consumed as substitutes for environmental goods, then economic growth may be fueled by environmental deterioration. In this context, undesirable economic growth may occur, characterized by an inverse correlation between aggregate capital accumulation and economic agents’ welfare.     

两类典型产业生态系统的建模及比较研究

基于两类典型的产业生态系统建立基本数学模型,提出清洁生产系数和耦合适应度系数概念,在运用数学模型对生态产业园区的几种类型进行解释说明的基础上,得出清洁生产具有广泛的适用性,生态产业园区和区域副产品循环网络具有相对的适用性,而技术创新是产业生态系统成功运行的关键因素等结论。     

唐山城乡居民消费对经济增长影响差异化的实证分析

作为多年来经济总量位居河北省第一位的唐山市,这几年国民经济得到了飞速发展,消费需求总量的逐步扩大在一定程度上对经济增长的拉动起到了举足轻重的作用。本文建立了城乡居民消费水平与唐山经济增长关系的误差修正模型,研究表明唐山城乡居民消费对其经济增长有正向拉动作用,城镇居民消费的拉动作用比农村居民的要大。因而,采取措施缩小城乡居民消费的差距,统筹二者的发展,是唐山完成两个"率先"的目标、建成全面小康社会不得不面对的问题。

Externalities, technological complementarities and sustained economic growth

Externalities as conventionally defined miss many of the spillovers that are both causes and consequences of the technological changes that underlie economic growth. We introduce a much wider concept called technological complementarities. New general purpose technologies (GPTs) rejuvenate the growth process by creating technological complementarities, which are adequately measured neither by total factor productivity (TFP) nor by externalities. There would be major gains from technological change even if the returns on capital invested in innovation never exceeded the returns on investing in existing technologies so that there were neither externalities nor positive changes in TFP.     

Potential production simulation and optimal nutrient management of two hybrid rice varieties in Jinhua,Zhejiang Province,China

Potential growth of two widely-grown hybrid rice varieties in the Jinhua district of Zhejiang Province, Shanyou63 for mid-rice and Xieyou46 for late rice, was simulated using a crop growth model of WOFOST. Parameters of the rice growth in WOFOST were calibrated through field experiments from 1999 to 2002 in Jinhua. The potential yield simulated with WOFOST was about 12 t/ha for Shanyou63 and 10 t/ha for Xieyou46, which are in good agreement with the highest recorded yield obtained in this area. Under farmers practice, current yield is about 7.5 t/ha for Shanyou63 and 6.5 t/ha for Xieyou46. There is a gap between the actual rice yield and the potential yield for these two hybrid rice varieties grown in this area. The attainable target yields were set to 70% to 75% of their potential yields for the two varieties. A recently developed software ＂Nutrient Decision Support System （NuDSS）＂ for irrigated rice was used to optimize nutrient management for these two rice varieties. According to NuDSS, the optimal fertilizer N requirement for the target yields was about 150 kg/ha for Shanyou63 and about 120 kg/ha for Xieyou46, which were only about 70% of the fertilizer N application under current farmers＇ practice. Comparing with farmers＇ practice, there is great potential to increase actual rice yields and to reduce fertilizer N use rates by improving rice crop management practice in Jinhua.
