Due to the practice of Taiwan’s six major metropolitan cites reform, not only 121 townships and cities transforming to districts, but many aspects have changed. Local autonomy was abolished, district heads were appointed by the government, and 70% of the population of Taiwan, which means sixteen million people or so, have lost their basic election rights. Metropolitan cities in Taiwan are centralized regimes. They are highly efficient in administration, but the value of democracy can be ignored and many issues in governance are generated including widening of urban-rural gap owing to the allocation imbalance of resources, decreasing of public participation, reducing of efficiency of local service and ill-exposing of local characteristics. These issues lead to decentralized governance. Decentralization governance can create numbers of merits such as reflection of diversified public opinions, power distribution, balance of efficiency and democracy, information transparency and decisions making by the public. All of such deepen democracy and eliminate the black gold politics.
