What role does statistical data play in national economy and government decision-making?

Statistics is a very important basic work of national scientific decision-making and modern management, which can provide direct data basis for the correct decision-making of national economic government. Since the reform and opening up, the scientificity and accuracy of China's statistical work have been continuously improved, and the statistical data generally reflect the trend of economic and social development. It has played a very important role in understanding the national conditions and national strength and serving the national economy and social development. However, in some places and some grass-roots units, there are still some violations of law and discipline in statistical activities, which are highlighted in the fact that some leading cadres, in pursuit of so-called political achievements, instruct statistical agencies, statisticians or statistical investigation objects to tamper with statistical data, and some statistical objects fabricate false data to defraud honor and interests. Or under the pressure of local leaders, fabricate false data, and some statisticians are also forced to participate in fraud. Some statisticians are not so strong in professional ethics, and they do not perform their duties of verification even though they know that the statistical data are wet, so they report it, which leads to some gaps in some statistical data and cannot objectively reflect the reality.
