中国地区经济增长差距的成因分析

通过综合现有的经济理论并结合中国经济实际，建立储蓄增长、投资增长与经济增长关系的理论模型，同时采用Ｇｒａｎｇｅｒ因果检测检验各地区三者间关系，并与模型结论比较。结果表明，东部地区的三者关系与模型结论基本一致，即投资增长、经济增长及储蓄增长间存在良性循环；而中部地区投资效率低下、西部地区资本供给不足，致使中西部经济中的三者良性循环被迫中断或被低水平恶性循环取代，从而导致地区经济差距急剧扩大。

Capacity,sustainability, and the community benefits of municipal utility ownership in the United States

ABSTRACT

Most literature on utility sustainability focuses on internal operations; this misses the role that utilities could play within a community. This study measures the impact of municipal ownership of water and electric utilities on the sustainability policymaking of local governments. I find that municipalities with government-owned water utilities adopt more sustainability measures than those with investor-owned service. Similarly, municipally-owned electric utilities have higher levels of energy sustainability in the community, but not in government operations. The utilities provide fiscal and technical capacity to municipalities. Interdepartmental coordination also strongly predicts sustainability policymaking. This study brings potential community benefits to the discussion of private investment in public service delivery.

Adoption of improved irrigation and drainage reduction technologies under limiting environmental conditions

Modern irrigation technologies have been suggested as a means of conserving scarce water and reducing environmental pollution caused by irrigated agriculture. This paper applies an economic model of technology selection that provides a general framework to analyzing adoption of irrigation technologies under various environmental conditions. Data from the San Joaquin Valley of California is used to verify the theoretical relationships. Results suggest key variables to be considered by policy makers concerned with adoption of modern irrigation technologies. Among these variables are crop prices, water technology costs, farm organization characteristics, and the environmental conditions of the farm or the field. Policy implications were discussed and analyzed.This research was conducted while the first author was a visiting scholar with the Dept. of Agricultural Economics, University of California, Davis, and USDA-ERS, USA.
