Based on a number of cracks identified in the crossframe connection angles in a skewed bridge,a widely accepted criterion that has been used in de-tailing the connection angle thickness to avoid cracking was determined to be un-conservative and over-simplified.

本文采用央行储户调查报告中未来物价预期指数、简单菲利普斯曲线方法和随机游走模型计算预期通货膨胀率,考察了通货膨胀预期对企业研发创新活动的影响及其内在机理。实证结果表明,高通货膨胀预期导致企业创新投入下降,且相比于民营企业,对国有企业的创新活动的负面影响更小。无论是使用高新技术行业子样本、剔除经济刺激年份、替换研发创新衡量指标或采用面板固定效应模型,均不影响结论的稳健性。对影响渠道的检验显示,高通货膨胀预期加大了企业在未来面临融资约束的可能性及市场竞争压力,对研发创新投入产生资源挤占效应。本文的贡献在于,揭
