居住在坦桑尼亚海岸附近岛屿的沿海居民是半自治的,并且是其邻近海洋和陆地环境的使用者。他们现在正面临一次经济转变,他们的生产计划已因此有所改变。我们用1993、1997和1998年的数据资料来评价沿海地区的个体是如何对环境和经济的变化作出反应的。评价集中在三个主要领域里:影响生产计划选择的潜在动力;生产限制以及风险多样化行为和在生存经济中的转变。结果显示,居民随着市场化的加深,他们的生产也不断专门化。此外随着生态系统的不断分化而开始进行生产资源的多样化,从市场价值和家用消费品结构改变的角度来讲,生存质量提高了。这次转变的结果是它增加了沿海居民收入的不平等性,其中最明显的是那些在他们生产计划中从事许多农业活动的个体。这种现象的原因可能是缺乏必要的金融手段来对新技术投资,以及在不同生产资源间的资本转移。
Coastal dwellers living on islands off the coast of Tanzania are semi-autonomous and are users of their immediate marine and terrestrial environment. They are now facing an economic shift and their production plans have changed accordingly. We use data from 1993, 1997 and 1998 to evaluate how individuals in the coastal areas react to environmental and economic changes. The evaluations are focused on three main areas: the potential drivers that influence the choice of production plan; the constraints on production and the diversification of risks and shifts in living economies. The results show that as their marketization deepens, their production continues to be specialized. In addition, the diversification of production resources as ecosystems continue to diverge and the quality of life improves in terms of market value and changes in the structure of household consumer products. The result of this shift is that it increases the income inequality of coastal households, most notably those who engage in many agricultural activities in their production plans. The reason for this phenomenon may be the lack of the necessary financial means to invest in new technologies and capital transfers between different productive resources.
