内陆待开发地区产业发展模式探讨——以内蒙古为例

以内蒙古为例，探讨了内陆待开发地区的产业发展模式，内陆待开发地区经济发展的主要制约因素是缺乏资金，缺乏技术，缺乏人才，因此，其经济发展必须有选择，有重点地优先发展部分行业。一般说来，待开发的内陆地区其经济发展必须以资源优势为依托，以市场为导向，开发优质名牌产品，发展优势产业，建设主导产业，带动地区经济的起飞。     

The Organization of Production in High Technology Industries: An Empirical Assessment*

Recent attention given to the concept of vertical integration and disintegration of production processes has identified the existence of a continuum, with small, flexibly specialized producers at one end and large, mass production units at the other end. Firms along the continuum constantly strive for the optimum combination of economies of scale and scope. This paper attempts to identify the organizational characteristics of high technology firms in one industrial complex of the U.S. Manufacturing Belt. A principal components analysis is performed on a number of theoretically relevant variables for a sample of high technology establishments in Northeast Ohio. The results indicate that the region contains a variety of organizational forms ranging from isolated workshops to large, vertically integrated assembly plants. These findings conform to expectations derived from recent conceptualizations in the literature. Additional empirical research will further enhance understanding of the processes that shape the organization of production in territorial complexes.     

从碱湖沉积和孢粉组合看内蒙古伊盟地区近5ka以来的古植被古气候变迁

内蒙古伊盟地区哈马尔太碱湖沉积特征和孢粉组合特征反映了该区近５ｋａ以来的古植被古气候变迁。研究表明，此期间该区植被由阔叶、灌木草原变为疏树灌木草原，最后变为荒漠草原。在这５ｋａ中存在两次暖期两次冷期，近１．６ｋａ以来以冷干为主。湿润气候只存在于４．５～５．５ｋａＢ．Ｐ．，气候总的趋势是由较湿润变干旱直至干燥。

Weights of Evidence Modeling of Mineral Potential: A Case Study Using Small Number of Prospects,Abra, Philippines

Weights of evidence (WofE) modeling usually is applied to map mineral potential in areas with large number of deposits/prospects. In this paper, WofE modeling is applied to a case study area measuring about 920 km² with 12 known porphyry copper prospects. A pixel size of 100 m × 100 m was used in the spatial data analyses to represent in a raster-based GIS lateral extents of prospects and of geological features considered as spatial evidence. Predictor maps were created based on (a) estimates of studentized values of positive spatial association between prospects and spatial evidence; (b) proportion of number of prospects in zones where spatial evidence is present; and (c) geological interpretations of positive spatial association between prospects and spatial evidence. Uncertainty because of missing geochemical evidence is shown to have an influence on tests of assumption of conditional independence (CI) among predictor maps with respect to prospects. For the final predictive model, assumption of CI is rejected based on omnibus test but is accepted based on a new omnibus test. The final predictive model, which delineates 30% of study area as zones with potential for porphyry copper, has 83% success rate and 73% prediction rate. The results demonstrate plausibility of WofE modeling of mineral potential in large areas with small number of mineral prospects.
