The 50% reduction of land value increment tax policy was implemented since 1st February 2002 and ended at 31st January 2004. The policy was enforced among every local government in Taiwan for two full years. For every local government, the degree of prosperity and the societal type of its city differs from each other. As for the policy itself, every county and city has different amount of lands to meet the qualification of the policy and different announced land current value. For example, Pingtung(«ÌªF) County is famous for agricultural production. In Pingtung County, although the policy uses half reduction of progressive tax rate to tax the land value nominally, the true origin of the tax is a ¡§public policy¡¨ that could affect the whole society. What has been affected or what has affected the policy on its implementation? Whether the prediction of real estate market boost and two times tax income of the Economic Development Advisory Conference are correct? This research is going to make a benefit evaluation of the policy¡¦s implementation. The research method of this research consists of survey, in-depth interview, and collection of governmental information and the research concentrated on presenting both objective and subjective perspectives, which will be showed in Chapter 3 and Chapter 4 for mutual proof of the policy¡¦s benefits. In terms of subjective evaluation, the land value increment tax policy benefited less then 20% for boosting the real estate market. On the contrary, according to our research result, 57.9% consider the policy as low interest loan, 70.6% thinks the policy is good for tax reduction, 76.6% thinks the policy is good for bankers, 52.4% thinks the real estate value never increased, 76% thinks the policy increases cases of ¡§faking trade but bestow in real,¡¨48.4% thinks the policy increase case of legal auction, 47.1% thinks it qualify for fair and justice, 44.3% thinks only consortium benefited from the policy, and 41.9% thinks the policy affected the social security. Among the objective governmental statistical information, it was found that the cases of legal auction indeed grew twice more. Before the implement of the policy, in 2001, there were 1890 cases. Since the implement in 2002, there were 3882 cases and 5839 cases in 2003.Furthermore, the issue of construction license and exercising of new house building also increased. In 2001, there were 1171 cases. In 2002, there were 1693 cases. In 2003, there were 2213 cases. However, during our in-depth interview, it was found that previous demonstrated growth of licenses was not due to the policy. The income of land value increment tax was 967805000NTD in 2001, 1160959000NDB in 2003. To sum up, the increment of real estate shifting cases and new built houses does not represent increment of tax income. Nonetheless, from both the subjective and objective evaluation, it is found that the policy is a good opportunity for tax reduction but not the primary reason for boosting land trading. It actually fastens the cases of legal auction, lower the bad debts and exceeding release ratio of banks, benefits only the consortium but shrink the budget of social security, and there might be no land tax in the incoming years. The policy does not meet the ¡§mark-up goes to the public¡¨ concept of the equal land right policy.
