科技创新效率是反映一个区域创新资源配置状况和创新质量的重要指标。文章利用DEA-BCC模型和Malmquist指数法对2012-2018年京津冀城市群科技创新效率进行静态和动态评价。以各城市每年的综合技术效率值为被解释变量,利用Tobit模型分析经济发展水平、政府支持、工资状况、外商投资水平、劳动者素质5个因素对城市创新效率的影响。研究结论表明:受规模效率偏低的影响,京津冀城市群的综合技术效率不高,但是随着时间的变化,城市创新的全要素生产率、技术效率不断增长,创新程度不断增强。同时还发现,政府支持、外商投资水平与城市创新效率是正相关关系,经济发展水平与劳动者素质对城市创新的影响不显著。

创新效率是反映工业企业创新资源配置和创新质量的重要指标。文章利用Malmquist方法对2010—2019年京津冀、长三角、珠三角三大城市群中38个城市的工业企业全要素生产率进行测算,来反映工业企业创新效率的动态变化。研究表明:“十三五”时期工业企业创新效率的发展态势好于“十二五”时期。随着时间的推移,三大城市群工业企业创新效率动态变化存在差异,京津冀城市群和珠三角城市群工业企业创新效率处于提升状态,长三角城市群工业企业创新效率略有下降。同时,全要素生产率变化受技术效率变化和技术变化的影响程度存在区域差异。据此,文章提出要加快区域工业企业协同创新共同体建设,加大经费和人员等创新要素投入,完善企业创新服务体系等建议。

基于1990-2013年中国月度CPI数据,本文通过运用分位数自回归模型和分位数单位根检验方法,研究了中国通货膨胀惯性的非对称特征,并分析了不同分位点上的通货膨胀惯性系数、单位根检验结果和半衰期。结果发现:中国的通货膨胀持续期存在明显的非对称特征,1998年之后通货膨胀持续性要显著低于1998年之前;相比于高通货膨胀水平,低通货膨胀水平上的通货膨胀持续性要显著降低。

Objective:To investigate the effect of dexmedetomidine on inflammatory factors and immune function in elderly patients undergoing laparoscopic radical resection of colorectal cancer. Methods: From April 2016 to April 2017, 86 cases of elderly laparoscopic radical resection of colorectal cancer in our hospital were selected and randomly divided into the observation group and the control group. 2 groups of patients were open venous access, oxygen mask, monitoring heart rate (HR), blood pressure (BP), electrocardiogram (ECG), oxygen saturation (SpO2), bispectral index (BIS), after induction of anesthesia, the observation group was given dexmedetomidine 0.4 g/kg to 20 mL of normal saline control. Group of 20 mL saline, 15 min infusion is completed, and the observation group of dexmedetomidine in 0.4 g/kg - h continuous infusion of normal saline control group, continuous infusion, until the end of surgery. Before induction of anesthesia (T0), 2 h after operation beginning (T1), at the end of operation (T2), 24 h after operation (T3) in venous blood, using ELISA method for the determination of serum interleukin-2 receptor (sIL-2R) and interleukin-6 (IL-6), tumor necrosis factor alpha (the level of TNF-alpha);on preoperative and postoperative 4 h, 12 h, 24 h after operation in venous blood serum epinephrine ELISA method (E), norepinephrine (NE), endothelin-1 (ET-1) level;on preoperative and postoperative 4 h, 12 h after surgery, 24 h venous blood flow cytometry determination of CD3+, CD4+, CD8+, CD4+/CD8+.Results:compared with before operation, the observation group after 4 h, 12 h, 24 h NE, and the lower control group E, NE and ET-1 increased, the observation group after 4 h, 12 h, 24 h E, NE, ET-1 lower than that of the control group;compared with T0, 2 patients in group T2, T3 sIL-2R, IL-6, TNF-alpha were increased, the observation group T2, T3 sIL-2R, IL-6, TNF- were lower than that of the control group;compared with the preoperative, 2 group after 4 h, 12 h, 24 h CD3+
