Just now, Mr. Kang mentioned that data quality is the lifeline of censuses. During this census, how did you ensure the collected data was authentic and accurate? Thank you.
Kang Yi:
I would like to invite Mr. He to answer this question.
He Ping:
Thank you for your question. The NBS always prioritized the quality of statistics data throughout the fifth national economic census. This census followed a well-designed plan, enhanced whole-process data quality control as well as the strength of statistical law enforcement, and enforced various measures, to effectively ensure the quality, authenticity and reliability of census data. We mainly adopted three approaches:
First, we ensured data quality at the source. During the census, we regulated the collection of data, combining three methods of data collection: census workers collecting data on site, self-declaration, and reports from various departments. The census registration was standardized in an orderly manner, with measures taken to prevent deliberate disruptions. We enhanced training and guidance for census workers and promptly responded to concerns over the census from the public and targets being surveyed to ensure that they better understood the census and maintained cooperation. During the census, investigations were combined, when a business entity operates under several different titles with the same workforce and independent accountability is not feasible. Entities and self-employed individuals without actual business activities throughout the year were excluded from the census. Therefore, we ensured that those being surveyed conformed to relevant regulations of the census plan so as to improve the quality of data at the source.
Second, we enhanced data verification and review. During the census, we increased the use of information technology with the aim of facilitating the self-declaration of data and improving the effectiveness of data verification. We diligently implemented the measures on census data verification and acceptance. Census data were verified immediately upon collection. We used big data analysis and comparison and data logic examination, among other technical means and evaluation methods, to verify and confirm data. After the census registration concluded, we organized data quality review and selective follow-up examinations to thoroughly test the quality of the census registration, and address problems discovered in the process, as well as similar or related issues.
Third, we effectively investigated and dealt with illegal activities and discipline violations. We maintained a zero-tolerance approach toward all illegal activities and discipline violations in statistical work, with no exceptions, to achieve full coverage and a long-term deterrent effect. We showed no leniency to any such behavior, responding immediately upon discovery during the census. Illegal activities and discipline violations discovered in some localities during the census were promptly investigated and dealt with. The NBS also urged relevant authorities to strictly pursue the liabilities of responsible personnel according to the law as well as Party and government discipline.
Thanks to the support of society, the cooperation of surveyed units, and the dedicated work of more than 2.1 million census instructors and enumerators nationwide, the fifth national economic census achieved high data quality. The comprehensive error rate through self-declaration was 0.47%. The data quality met the control standards. Thank you.
