昆明市“十四五”时期国土空间规划GDP发展指标预测与分析

作为国土空间规划中的核心指标,地区生产总值(GDP)的预测与分析结果直接影响着地区各项专项规划和未来经济社会的发展,本文依据云南省昆明市历年GDP发展水平、社会状况及昆明市“十四五”时期经济社会发展纲要指标要求,采用非线性预测中的多项式预测与指数函数预测,对昆明市“十四五”时期经济社会发展主要指标中的GDP指标进行预测与分析,在对GDP指标预测的基础上,对预测结果进行修正,实现对昆明市“十四五”时期经济社会发展GDP指标的准确控制及优化,并将最终分析结果和市政府下达的指标进行验证,契合度较高,可见本文采取的方法有较高的可执行性,对正在开展的昆明市“十四五”时期经济社会发展各项主要指标预测与分析有较强的指导和借鉴作用。     

Co-evolution of three mega-trends nurtures un-captured GDP – Uber’s ride-sharing revolution

Uber used a disruptive business model driven by digital technology to trigger a ride-sharing revolution. The institutional sources of the company’s platform ecosystem architecture were analyzed to explain this revolutionary change.Both an empirical analysis of a co-existing development trajectory with taxis and institutional enablers that helped to create Uber’s platform ecosystem were analyzed.The analysis identified a correspondence with the “two-faced” nature of ICT that nurtures un-captured GDP. This two-faced nature of ICT can be attributed to a virtuous cycle of decline in prices and an increase in the number of trips.We show that this cycle can be attributed to a self-propagating function that plays a vital role in the spinoff from traditional co-evolution to new co-evolution. Furthermore, we use the three mega-trends of ICT advancement, paradigm change and a shift in people’s preferences to explain the secret of Uber’s system success.All these noteworthy elements seem essential to a well-functioning platform ecosystem architecture, not only in transportation but also for other business institutions.     

油库容量确定方法探讨

随着我国经济的迅速崛起,油库建设也得到飞速的发展。然而有些油库在建设或者改造过程中,油库容量确定不合理,影响油品的正常供应,给油库经营带来很大的不便。本文以某油库为实例,通过GDP（国内生产总值）预测法和一元线性回归预测模型法就合理确定油库容量进行探讨。     

径向函数网络对国民经济生产总值预测研究

为了建立国民经济生产总值（GDP）神经网络预测模型,构造了双层网络结构的基于径向基网络,通过学习训练,确定径向基数神经网络参数和结构。仿真结果表明,生成的径向基函数模型应用于国民经济预测比BP神经网络模型具有更高的预测精度和良好的泛化能力。     

山东省社会用电量与生产总值指数的回归分析

对山东省 1978～ 1999年国内生产总值指数与全社会用电量做了对数线性回归分析 ,进一步对模型进行了相关性检验 ,通过一阶差分变换对模型进行了修正 ,最后得到合理的回归方程。用此模型对山东省“十五”期间的全社会用电量进行了预测。     

落实节能降耗目标的主要障碍分析

从“十一五”规划开局第一年的单位产值能耗情况看，完成规划节能降耗的目标存在很大的难度。为了能够实现预定的节能降耗目标，制定政策和措施，需要认真分析难点的根源所在。     

China is moving away the pattern of “develop first and then treat the pollution”

Confronted with the rising costs of environmental degradation associated with rapid economic growth, the top Chinese leaders have gradually recognized that the conventional path of encouraging economic growth at the expense of the environment had to be changed. In order to avoid the situation that its rampant environmental pollution problem will only worsen before it gets better, China's environmental regulatory agency is trying to change the incentive structure and establish an institution for fundamentally ensuring local officials to be more environmentally responsible for their decision making.
