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.

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.     

论网站信息流整合及其对人流的导引

网站信息流是互联网信息传递的基本形式和唯一介质，是众多形态“流”中最具影响，并对人流的产生与变化发挥巨大的导引作用。本文以网站信息流的整合为切入点，从信息流受众接受信息的角度出发，将网站信息流对人流的导引视为主动式导引、被动式导引和互动式导引，剖析了与网站信息流导引密切相关的多种人流规律。

实施铁路建设投融资渠道和方式变革，实现铁路建设跨越式发展

铁路建设资金投入是实现铁路跨越式发展的一个重要方面。按照目前每年500亿元～600亿元的资金投入,是远远满足不了铁路建设的需要。铁路建设资金结构不尽合理,融资渠道狭窄,融资方法单一,对社会资金利用有限等是束缚我国铁路建设的重要问题。因此应从继续发挥政府投资的主渠道作用;提高国铁的融资能力;扩大债务性融资力度;深化股权融资、项目融资;开展租赁融资等方面,实施铁路建设投融资渠道和方式变革,为实现铁路建设跨越式发展提供资金保障。     

论庄子视野中的理想人格

庄子坚持从“他人为尊”、与人为善的“以鸟养养鸟”人格立场出发,追求人格的完善、独立和自由。庄子认为,要真正实现人格的完善、独立和自由,就必须挣脱物质和人身的依附关系,过平易恬淡的生活,不因所谓人生的辉煌腾达而改变自己高洁的志向,也不因生活窘困而变得庸俗不堪;并且,还必须在此基础上,进一步参透生死,依据自然的内在法则傲立于天地之间,从宇宙大道的立场观照死,从而达至内在与外在、天与人的和谐圆融的审美理想人格。庄子审美理想人格不是现实人格的简单复制或摹仿,它导源于、却又超越于现实生活中的各种人格,这本身彰显了庄子某种积极“入世”的对于社会民生困境与出路的深层关切。     

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.
