Currently, many developed countries have established super-ministry system and promoted "one-stop" service. The research team gives examples: South Korea has been promoting the super-ministry system, from which Guangdong should draw concentrative lessons. After all the previous reform, the government agencies of South Korea are in smaller quantities but of better quality, with only 15 ministries making up the central government. The super-ministry government structure brings convenience to the management of enterprise investment, due to fewer involved ministries, fewer steps of examination and approval and more fluent hand-over and take-over between ministries. Sometimes, procedures relevant to enterprise investment can be done in one single ministry. Singapore also owns similar administration structure. In addition, Singapore has set up an “one-stop” service center, in which enterprises and citizens can finish all the procedures at one wicket. Such measures have improved the working efficiency, avoided multiplying corruption and optimized the investment environment to great extent.
