Adoption of new tobacco varieties in Greece: Impacts of empirical findings on policy design
研究了希腊烟农采用新型烤烟品种的影响因素，发现农场规模、离城市远近、多样化程度和烟农年龄是关键，而制度接触次数反而与采用负相关，为烟草政策设计提供参考。
Greece is a major international tobacco producer. Flue-cured tobacco varieties constituted the major alternative crop to Greek farmers growing certain oriental tobacco varieties. Diffusion of flue-cured tobacco was rapid due to its high yields and the depressed market for certain oriental tobacco varieties. Currently, the common organisation of the tobacco market is undergoing substantial changes, and the farmers' response will be a vital factor of success. A portfolio selection model reveals that the major factors influencing the adoption decision of tobacco growers are the size of the farm measured in annual work units, the farm's proximity to urban centres, the farm's diversification and the farmer's age. The number of contacts with institutions is, surprisingly, inversely related to adoption. Future tobacco policies impinging on factors influencing decisions to adopt new varieties or production practices may be more cost-effective. © 1998 Elsevier Science B.V. All rights reserved.
