制度创新与中国农业发展——兼论农业产业化的意义

在工业化的前提下,通过农业的技术进步促进农业发展是新古典经济学传统农业改造的核心思想,但其局限性是显而易见的。以新制度经济学的理论来看,中国农业问题的症结是以农户为基本经营单位的农业生产组织形式不能适应市场经济的要求,农业产业化是中国农业现代化的必由之路。

宏观经济政策与资本形成机制的契合——资本市场的宏观经济意义分析

资本形成机制的宏观经济含义体现为实现国民收入的良性循环,这一良性循环不只是消费、积累比例的确定,还体现在形成投资的现实效益,这种效益很大程度上体现为经济结构的优化。宏观经济政策在资本市场的传导,便以现实的资本形成机制的顺畅运行为前提。资本市场作为资本形成的实现机制,其宏观意义体现在其对宏观经济政策的顺畅传导中。     

美日两国产业结构政策比较

日本产业从战后的废墟中得以重建和繁荣,并以惊人的速度赶超欧美,成为世界第二大经济强国,日本政府英明的产业结构政策功不可没。然而面对20世纪90年代日本经济的极度萧条,政府的产业结构政策已无回天之力。相比之下,美国政府通用的产业结构政策却引导美国的产业发展在信息时代仍然处于不败之地,这不能不引起我们的思考。     

新形势下我国耕地保护的长效机制研究

耕地是人类赖以生存的物质基础，是国民经济和社会发展的宝贵资源，耕地数量的多少和质量优劣直接关系到国家粮食安全和社会稳定。因此，在新形势下，如何保护好有限的耕地资源，促进经济社会科学、合理地发展，已成为当今世界的重大课题。本文根据我国耕地减少的现实危机及原因，提出一套科学、合理的耕地保护长效机制，力求为进一步有效地保护耕地资源提供理论基础和现实途径。     

Does price reflect emotional,structural or performance quality?

Three denim jeans products from the same manufacturer with differentiated pricing and labels (antiqued, sandblasted, and stonewashed) were used to determine the relationship between price and quality. Both qualitative and quantitative procedures were used to analyse the garments. All three jeans were made of twill weave with 3 × 1 repeat. Both structural and performance characteristics were compared using standardized tests. Analysis of variance was used to compare the selected structural and performance characteristics among the three jeans products. Tukey’s HSD tests were used for post hoc multiple comparisons for three jeans. The findings revealed that despite the fact that all three jeans products were from the same store, and that the fabrics used the same weave, degree and direction of twist, the jeans differed significantly for several structural and performance characteristics. Several possibilities for future research were explored.

On the test of the correction mechanism for mis-pricing between assets using a statistical yield spread model

This paper investigates the existence of a correction mechanism for mis-pricing between Japanese stock and bond. By this correction mechanism we mean that when deviations occur from the equilibrium levels of the expected return differentials between stock and bond — the risk premium differentials, the market will tend to correct the mis-pricing and bring the expected return differentials back to the equilibrium levels. We assume that the yield spread between the predicted earnings price ratio of stock and the yield to maturity of bond reflects the risk premium between stock and bond, and estimate the equilibrium risk premium differentials and mis-prices between stock and bond by modelling their behaviors with a statistical yield spread model (SYS). Empirical results strongly indicate the existence of the mis-pricing correction mechanism, suggesting the inefficiency of securities markets.
