In the last two years, the central and state governments have ushered in more than 10,000 reforms. Thanks to this, India has made a significant jump of 42 points in the global ‘ease of doing business' index," the Prime Minister said."As part of these reforms, more than 1,400 laws have been repealed. Major tax reforms have been brought in."Modi said the Goods and Services Tax (GST) had been the "biggest tax reform since independence" that had made the entire country into a single market and had widened the tax base.He said infrastructure development was taking place at a "record speed" with more than 10,000 kilometres of national highways built in the last one year."It means over 27 km road built per day. This rate is double as compared to road development during previous governments."
