PM Narendra Modi launched a series of policies and measures to revitalize economy and reform government since he came to power in 2014，and tried to promote the transformation of Indian economic development strategy and correct the structural bias of Indian economy through the supply-side revolution. Modi government’s transformation of development strategy has brought some achievements in 2 years：the fundamentals of Indian economy show good signs，India’s growth rate has surpassed China’s and still maintains strong momentum，which caused widespread controversy in the international community on the sustainability of India’s growth，and whether the economic competition between China and India has entered an era of transition. This article analyzes and summarizes the characteristics of Modi government’s economic development strategy，and the pertinence and deficiencies for inherent economic issues and emerging issues of India by contrasting and observing the historical heritage of India’s economic development. Once the development strategies are made，it will become the direction and guidance of a country’s macroeconomic development in the long term，so the study on Modi government’s development strategy and its implementation will contribute to analyzing and predicting India’s economic development prospects and its impact on China to a certain extent.
