If the specific circumstances of different companies are different, the time from enterprise restructuring to listing should depend on the specific circumstances, and the overall time is more than one year. Under normal circumstances, the approximate time of each stage is as follows: it takes about 6 months from planning restructuring to establishing a joint stock limited company, and the time for changing a standardized limited liability company into a joint stock limited company can be shortened; It takes about 3 to 4 months for sponsors and other intermediaries to conduct due diligence and produce application documents; Theoretically, it takes about 3 to 4 months from the examination by China Securities Regulatory Commission to the issuance and listing, but the actual operation time is often about 1 months. However, it can be seen from the above that the preparation time for listing varies from enterprise to enterprise, so it is difficult to generalize, and sometimes it has a great relationship with the personality characteristics of the top leaders of enterprises and the professional level of intermediaries. From practice, it is very fast to declare within one year, and there are many cases of preparation for three to five years. This has not taken into account the influence of policy factors such as the suspension of acceptance by the CSRC during the period or restrictions on special industries.
