Two-dimensional code investigation method and system

Abstract

The invention relates to a two-dimensional code investigation method. The two-dimensional code investigation method comprises the main steps that (1) the investigation content is compiled into a questionnaire; (2) an answering ID (Identification) is generated by the questionnaire; (3) two-dimensional codes are generated by the answering ID; (4) the two-dimensional codes are printed on a carrier; (5) a respondent scans the two-dimensional codes to participate in the investigation by virtue of a two-dimensional code scanning tool; and (6) information which is submitted after the respondent answers is recovered, cleaned and stored, and data processing and statistics are carried out on the basis of recovering the information. The invention also discloses a system for realizing the method. Due to the adoption of the method and the system, the conventional passive investigation of the respondent is changed into active participation type investigation, the investigation process breaks through the limitation of territory, time and equipment environment, and the investigation content has the advantages of abundance and the like.

Description

technical field [0001] The invention relates to a method for investigating two-dimensional codes. [0002] The invention also relates to a system for implementing the above method. Background technique [0003] According to the different ways in which the investigators contact the survey objects, the existing market research information collection methods can be divided into four categories: face-to-face surveys, telephone surveys, postal surveys, and e-mail surveys. [0004] 1. Face-to-face investigation [0005] In face-to-face surveys, investigators usually conduct on-the-spot sampling according to the region to find suitable survey objects, and conduct face-to-face direct contact with the survey objects, conduct surveys by asking me to answer, and record the results of the survey objects on the spot. Face-to-face surveys include home visits (investigators go to the respondents' homes to conduct surveys), street interception interviews (investigators intercept responden...

AI Technical Summary

Problems solved by technology

[0014] 2.1. Large time limit: the call time must be in the free rest time of the survey object, later or earlier will not work

Respondents cannot freely arrange the investigation process according to their own time

[0015] 2.2. High investigation cost: computer-aided telephone interview finds the survey object through random dialing, with low success rate and high investigation cost

[0016] 2.3. High difficulty in investigation: Due to the flood of sales calls in China, people are becoming more and more disgusted with answering unfamiliar calls, and the rejection rate of telephone surveys is getting higher and higher

[0017] 2.4. The content of the survey is limited: pictures, audio and video cannot be presented, and the answers to questions with a large number of options and open questions are not effective, and the effect of sensitive questions is not good

[0023] 4.1. R
