【摘要】：李克特式量表可以定量地对指标进行评价,常常被用在包括区域科技创新环境在内的各种排名与其它统计分析中。李克特式量表在应用时首先设置不同选项(等级),要求受访者从中选择比较符合要求的一项,最后通过调查者赋予不同等级的选项以不同分值,进一步定量地计算所有受访者对该项测量指标的总体评价。然而,在李克特式量表中,问卷设计者主观赋予的不同等级分值与受访者认为的赋值可能存在一定的语义差异,从而导致测量结果在有些情况下不能充分反映受访者的真实态度,进而影响统计分析结果的可靠性。首先对语义差异进行了论述,然后通过李克特量表对区域科技创新环境排名的具体应用中语义差异导致的有效性问题进行了算例分析。此后,采用数值分析和数理推理方法,分析了确保调查结果可靠性的语义差异范围,并且给出了降低语义差异对李克特式量表排名影响的等级分值赋值方法。最后,通过一个实例分析了所探讨的问题并演练了相应理论结论的应用过程。
[Abstract]:The Richter scale, which can be used to evaluate the index quantitatively, is often used in various rankings and other statistical analyses, including the regional scientific and technological innovation environment. The Richter scale was first used with different options (rank, which asked the interviewees to select one that met the requirements, and finally, through investigators, to assign different scores to the options of different grades. A further quantitative calculation of the overall evaluation of the measure by all interviewees was made. However, in the Richter scale, there may be some semantic differences between the subjective scores assigned by the questionnaire designers and the assigned values of the respondents. As a result, the measurement results can not fully reflect the true attitude of the interviewees in some cases, and then affect the reliability of the statistical analysis results. Firstly, the semantic differences are discussed, and then the validity of the semantic differences in the application of the regional scientific and technological innovation environment ranking is analyzed by using the Richter scale. Then, the range of semantic differences to ensure the reliability of the survey results is analyzed by numerical analysis and mathematical reasoning, and the method of rating assignment is given to reduce the influence of semantic differences on the ranking of Richter scale. Finally, an example is given to analyze the problems discussed and the application process of the corresponding theoretical conclusions is drilled.
