Brief introduction to the existed industrial classification in China,CSIC Rev. 2002 was revised on the basis of the classification standard in 1994 (CSIC Rev. 1994).,CSIC Rev. 2002 has been greatly modified and adjusted, comparing with previous version in 1994.,The total number of the categories in each four levels of the new classification has been increased,section has been added by 4; division has been added by 3; group has been added by 28; class has been added by 67,In the view of specific classification categories, some categories have been added while others reduced.,On the one hand, the new classification of version 2002 especially focused on the classification of service,From section E to section T,The section added by 4the division added by 3the group added by 31the class added by 124,On the other hand, we make the categories greatly reduced in the section Mining and Manufacture,Mining reduced by 20 classesManufacture reduced by 62 classes,The final revision,no changes, reduced or cancelled, further subdivided from the original class, respectively takes up 1/3 each.,2. The improvement of corresponding method between the new classification and the old,In CSIC revision 2002, we have changed the old method,Not only listing a changing process for the each category with written explanation,But also listing detailed corresponding code and title of the new and old classes,There are three kinds of corresponding relations:,no changesreduced or cancelledfurther subdivided from the original class,NBS has also developed two kind of software,one is for the conversion between the new classification and the oldanother is CSIC Inquiry System,3. The method and experience for conversion of data for Chinas Basic Unit Database,The Government Statistical System of China,The different condition for statistics foundation in various provinces The different conversion method in each province also,There are primarily two kinds of methods,One way,The improvement of the new-old corresponding method makes it possible to use computer to adjust history data,Most provinces have adopted this kind of data conversion method to adjust the unit database,The number of industry classes of the 2002 version,no changes, deleted, subdivided to new industry classes, respectively occupy about 1/3 of the total number,376 industry classes can (one-to-one) be directly converted,another 388 old industry classes can be directly merged into the nearly 200 new industry classes .(multiple-to-one),The remaining industry classes (around 1/3 one-to-multiple),can be further determined respectively with the primary activities filled into questionnaire by the units.,The census data show,the number of the corporate units in each region is around several hundred thousand. the maximum number of corporate units will be more than ten thousand in county level,Another way,To add an indicator of new industry code in the 2002 basic unit survey questionnaire, fill out the code of new and old industries respectively in accordance with the primary activities filled out by enterprises or units,In comparison the two methods each have their advantages and disadvantages.,This shows,The first method that uses correspondence conversion software can apparently reduce the workload of statistics office at basic level and increase work efficiency,This shows,The second method of re-determination of the industries involves huge workload, yet data quality collected by the second method will be relatively higher.,One point is important,The conversion work of the data must be don
