The development of North-Western construction industry is mainly fit for the social and economic development of the region. But the levels of main economic indexes of the industry are lower than the average of Chinese construction industry, and there are gaps between the profit situation and the industrial scale and production capacity. These two questions are mainly caused by the structural default of segment trades in this industry. There will be a large scale construction market that will be caused by huge...

The development of North-Western construction industry is mainly fit for the social and economic development of the region. But the levels of main economic indexes of the industry are lower than the average of Chinese construction industry, and there are gaps between the profit situation and the industrial scale and production capacity. These two questions are mainly caused by the structural default of segment trades in this industry. There will be a large scale construction market that will be caused by huge sum capital investment in North-Western territory in next Five-year Plan. To meet this demand,this paper gives some suggestions as fouows: First,segment trades structure in the industry should be improved. Second, skeletal general contractors should be developed. Third, joint-contract with advanced construction enterprises should be advocated on advanced projects. Forth, construction market of other regions should be developed. Finally, the management of this industry and contractors should be improved.

西北建筑业发展水平与该地区社会和经济发展水平基本适应。产业主要经济指标均低于全国建筑业平均水平,并且获利水平与其规模和生产能力之间存在较大差异,主要由产业内部细分行业结构缺陷导致。为适应“十一五”期间巨额固定资产投资所形成的西北建筑市场需求,西北建筑业应着力改进和完善内部细分行业结构,培育强势总承包企业,在不具备独立承包能力的先进项目上与区外企业开展联合承包,在优势领域拓展区外市场,改善建筑业行业和企业管理。

BP neural network is an effective method to deal with complex and nonlinear problems. It has been widely used and gradually applied to deal with problems of macroeconomics at present. In this paper, the author systematically combines econometrics with BP neural network,and improves BP neural network predictive model for research economics field problems, which is based on causality theories to determine the input variable of BP neural network, on coitegration theories to analyze the reliability of BP neural network system, and on the momentum BP algorithm of alterable learn rate. It strengthens the theoretical basis and improves the quality of network model. The improved BP neural network has been applied to predict and control northwest construction industry and the results are satisfactory.

BP神经网络是分析处理复杂非线性问题的一种有效方法,是目前广泛应用的一种神经网络,已被逐渐应用于对宏观经济问题的研究中。本文有机地整合了计量经济学与BP神经网络,建立了基于因果关系理论来确定BP网络的输入变量,基于协整理论来分析BP网络系统的可靠性,基于学习率可变的动量BP算法的用于研究经济领域问题的改进BP神经网络预测模型,加强了网络模型的理论基础,提高了网络模型的质量,并将其应用于西北建筑业的预测和控制中,取得了令人满意的效果。
