Validity of unbalanced growth theory and sectoral investment priorities in Indonesia: Application of feature ranking methods

This study develops a new approach for testing the validity of unbalanced growth theory as well as determining the sectoral priorities for investment in Indonesia over the period 1995–2015. To this end, the high linkage sector(s) is identified through the input–output framework. Afterward, two different approaches, multiple linear regression and multi-layered perceptron (MLP) artificial neural network, are applied to capture the linear and nonlinear relationships between the extracted engine sectors and gross domestic product growth. Given that the detection of sector ranking is crucial for preparing a proper development plan, in the same vein we apply two types of feature-ranking methods (namely, stepwise regression and ant colony optimization (ACO-MLP based). The findings suggest a consistent relationship between the theory and economic growth in both linear and nonlinear models. However, the nonlinear model outperforms its competitor. In general, we find that the manufacturing sector is the most strategic sector in Indonesia, as it has been ranked first in both linear and nonlinear forms. Hence, its development path could be reinforced by more investment in this leading sector and then followed by investment in construction, hotels and restaurants, and agriculture.

Technological Change and Economies of Scale in U.S. Poultry Processing

This article uses a unique data set provided by the Census Bureau and a translog cost function to empirically examine technological change in the U.S. poultry industry. Results reveal substantial scale economies that show no evidence of diminishing with plant size and that are much greater than those realized in cattle and hog slaughter. Findings suggest that consolidation is likely to continue, particularly if demand growth diminishes, and that controlling for plant product mix is critical to accurate cost estimates.

Determinants of efficiency of vegetable production in smallholder farms: The case of Ethiopia

Improving production efficiency remains as a plausible means of increasing productivity when resource reallocation, and the creation and adoption of new technologies are limited. Technical, allocative and economic efficiencies are derived from a sample of smallholder vegetable farmers in Ethiopia using parametric and non-parametric methods. The results reveal that the two methods yield similar estimates and the existence of substantial inefficiencies in production as well as efficiency differentials among farmers. The analysis of the determinants of efficiency of vegetable production using regression models show that low asset ownership, illiteracy, large family size, inadequate extension contacts, small farm size, age, low off/non-farm income and high consumer spending are the major socio-economic factors causing inefficiency of vegetable production in the study areas. A comparison of the market-driven (vegetables) with the whole-farm (crops and livestock) production efficiency indicates that lower economic efficiency scores for the former might be related to the limited access to capital markets, high consumer spending, and large family size.     

基于共同管理的渔业管理制度分析——以日本为例

日本渔业资源管理能够在一定程度上避免公共资源利用的悲剧,使日本周边水域主要鱼种及其种群的资源状况逐渐得到恢复和改善,主要归功于适合的渔业资源管理制度和其实施主体——渔业管理组织.论文对日本渔业管理制度的历史变迁和管理组织的特征进行分析,试图从制度分析的视角,利用渔业相关统计数据,以期探讨日本渔业管理的成功经验,为重塑我国渔业资源的科学管理和可持续利用管理架构提供有益的借鉴.     

珠海市建设用地变化时空特征及其驱动力分析

应用ArcGIS将研究区域不同时期的土地类型图进行叠加,并将得到的土地覆被变化图与地形图进行叠加;运用SPSS软件对建设用地变化影响因素进行相关分析。研究结果表明:①1990年代以来,珠海市建设用地面积呈总量上升趋势,在三个研究时段内经历了"快速变化—缓慢变化—快速变化"的过程,耕地是新增建设用地的主要来源;②建设用地空间分布格局发生变化,重心由香洲区逐渐向斗门区和金湾区倾斜。研究结论:本区域建设用地变化与地形因素关系密切,在地势低平、坡度较小的平原区变化较剧烈,经济发展和人口增长因素是建设用地变化的最直接驱动力,同时还受政策因素的导向作用。
