The paper develops a new measure of development, namely, development quality Index (DQI), to compare performance of China and India. The results show that national level development quality grew three times faster in China than in India. Conversely, the health quality grew three times as fast in India than China over the period 1980-2004. The overall regional development quality level improved in both countries, but polarization widened in China. The sign of inter-regional polarization in China indicates a rising concentration of development gains from economic reform policies, while in recent years there are trends of polarization in economic dimension of DQI in India.
