林毅夫. 90年代中国农村改革的主要问题与展望. 管理世界. 1994;(3):139-144.Abstract

一、中国农村改革的成就与面临的新问题中国农村改革与发展取得了举世瞩目的成就。在组织与制度创新方面,打破了单一公有制的所有制格局,以合作制为主体,多种所有制并存且相互交融的格局已基本形成;集中度颇高效率却很低下的传统计划机制随着其组织载体——人民公社的解体,对农业生产经营和流通的影响力大大下降,市场机制在农村资源配置中的作用则越来越明显,政府也正在着力进行利用经济参数调控市场的尝试。在经济增长方面,联产承包责任制的广泛推行有力地加速了农业增长,1978～1992年,农业总产值年均增长速度达到了5.9％,增长速度最低的1984～1988年间也达到了4.1％,分别超过了对应时期人口的增长率(1.4％、1.6％)3.5个和2.5个百分点,这不但一举结束了多年来农产品总供给始终不足的历史,而且较为明显地改善了城乡居民的膳食结构;乡镇企业的异军突起改变了农村的产业结构,也促进了农村居民收入的增长。

1 Introduction The technology of the laser-heated pedestal growth (LHPG) in making single crystalsand fibres is based on the Czochralski technique, which makes use of a laser as heaterto produce all kinds of high melting temperature oxide single crystal materials. Inthe early 1980s, the Bell Laboratory in USA produeed some kinds of single cryatalsand fibres having special properties by using this technique. Since 1986, high-T_csuperconducing fibres have been produced in many laboratories of LHPG insome countries, and the Institute of Metal Research, Academia Sinica,also built an experimental apparatus financially supported by the NationalSuperconducting Centre specially to study the superconducor.

厉以宁. B股对内开放利大于弊. 山东金融. 1994;(2):42.Abstract

Ｂ股对内开放利大于弊厉以宁人民币特种股票（Ｂ股）的发行曾被国内经济界寄以较大希望，认为这是吸引外资的又一条有效途径。但没有隔多久，Ｂ股市场便一蹶不振，交易日益萎缩，新发行的Ｂ股无人间津。迄１９９３年八月中旬为止，市场上的Ｂ股股价前景始终黯淡。不少人发...
