摘要
为研究新型城镇化进程对消防安全工作的影响,筛选出能够综合评价河北省各市新型城镇化水平的17项统计指标,利用因子分析法对指标进行分析并提取出4个公因子。选取2012年数据对各市消防4项指标与新型城镇化4个公因子做多元相关分析,结果显示:火灾次数与4个公因子呈正相关关系;死亡人数、受伤人数和直接经济损失与4个公因子的回归模型拟合效果差,无法得出这3项指标与4个公因子之间明显的相关关系。受伤人数与城建和交通公因子的偏相关系数为0.568,说明二者之间具有一定的正相关性。
In order to study the impact of new urbanization process on fire safety,17 statistical indicators were filtered out which can comprehensively evaluate the new urbanization level of different cities in Hebei province.The factor analysis method was used to analyze the indicators and 4common factors were extracted.With the help of the statistical data got in 2012,a multiple correlation analysis was conducted on the 4firefighting indicators of each city and the 4common factors of the new urbanization.The result revealed that fire frequency was positively correlated with the 4 common factors;the regression model formed by death toll,the number of the injured and the direct economic losses with the 4common factors did not have an effective fitting.Therefore it cannot conclude that there was a significant correlation between these 3indicators and the 4common factors.Because the partial correlation coefficient of the number of the injured with the common factor of urban construction and transportation was 0.568,it indicated that a certain positive correlation exists between them.
