A visit to one of Changsha's newest success stories offers an example of the government's methods. Hunan Sunzone Optoelectronics, a two-year-old company, makes solar panels and ships close to 95 percent of them to Europe. Now it is opening sales offices in New York, Chicago and Los Angeles in preparation for a push into the American market next February. To help Sunzone, the municipal government transferred to the company 22 acres of valuable urban land close to downtown at a bargain-basement price. That reduced the company's costs and greatly increased its worth and attractiveness to investors. Meanwhile, a state bank is preparing to lend to the company at a low interest rate, and the provincial government is sweetening the deal by reimbursing the company for most of the interest payments, to help Sunzone double its production capacity. Heavily subsidized land and loans for an exporter like Sunzone are the rule, not the exception, for clean energy businesses in Changsha and across China, Chinese executives said in interviews over the last three months.
