housing prices, associated with mega cities’ growth.
As a result, real estate developers in Ningbo would choose to build new housing towers which are close to the new public transportation stations. Also, it would stimulate commercial real estate demands, so it is estimated that shopping agglomerates and upscale restaurants will be built close to these transit stations. Because developers have more investment options so they can reduce the competition for the prime sites in the traditional central business district. As transit stations are usually built in the suburban areas, the development of less developed areas will be speeded up.
5.25 Impacts on the land use
Kahn also states that like Internet, the high speed rail can play a similar role. The bullet trains can attract back office activities and help enterprises fragment, so they are able to send their routine activities to less expensive land at the periphery while keep their deal makers in the costly commercial real estate in the mega cities. The rapid development of high speed rail, such as Hong Yong High Speed Rail, can help to provide a more efficient allocation of business activities across space, which is beneficial for firms to control costs. It is considered to be a “win-win” strategy because the scarce and expensive land in the mega city, like Hangzhou, is efficiently utilized, at the same time, the second tier cities, such as Ningbo, can experience local growth (Kahn).
5.26 Impact on industrial clustering
According to a report conducted by Siemens, high speed rail can help to drive local economies by linking centers of knowledge, finance and technology (Siemens). All these factors are supportive to industry clustering. In 2013, the American Public Transportation Association conducted a research on the role of transit in support of high growth business clusters in the United State. It points out the importance of transportation. Transportation agencies should be able to provide adequate capacity to serve the industrial clusters. The study shows that traffic congestion can have a negative impact on the growth and productivity of densely developed districts by increasing travel times. Also, it may erase the agglomeration benefits. Researchers found that that “doubling the number of jobs accessible within 20 minutes of driving time leads to an increase in real average wages of 6.5%, while the impact for a similar increase within 20 to 30 minutes is as small as 0.5%.”
In the case of Ningbo, it is one of largest providers in Chinese clothing industry. Currently, there are over two thousand clothing producers in Ningbo, and their production capability can reach as high as 1.4 billion sets per year, which accounted for around 12 percent of the overall production capability in China. Favorable locational conditions can accelerate the development of industrial clusters. This high speed rail line connects Ningbo with other cities, making the transmission of knowledge be easier.

6. Conclusions 总结

The industrial structure is gradually optimizing, but the proportions of three sectors of economy are not optimal.

• The structural level of three sectors is not high.
• The scale level of secondary sector is low and the concentration level is not high.
• Regional transportation convenience in Yan
