The PPP mode aims to establish a long-term cooperative relationship between the government and private capital. Private capital bears most of the work of infrastructure design, construction, operation and maintenance, and obtains a reasonable return on investment through "user payment" and the necessary "government payment".

However, from all localities to promote the practice of PPP, we still face many challenges. In some places, there are difficulties in landing projects and applauding them.

Insiders pointed out that the most difficult problem in the current PPP project is different ideas.

Local governments and departments regard it as a channel for investment and financing. Social capital wants to recover capital and technology as soon as possible, and some even hope to get huge profits from it.

And "whether the government can act according to the contract is the biggest concern of public funding."

Jin Yongxiang said.

For the public welfare projects that are hard to make profits in the course of urbanization, Jin Yongxiang said that the government can not see it as a "burden". Actually, from all localities, there is no lack of private capital from PPP projects. The key is that the government should change its concept, design the cash flow of the project, and ensure the return of the public capital through the government's purchase services and the feasibility gap subsidy.

For private investors, Sun Jie believes that there should be a correct view of profitability.

"The PPP project should ensure profitability, but not profiteering."

He suggested that the current PPP involving government funded services has been included in the budget, but the portion of the services purchased by residents has not yet been included in the budget.

But there is no problem of profiteering.

Can the PPP project become the cake that the three parties of the government, enterprises and society like to eat? The key is to perfect and refine the system construction.

Introduction, at present, the Ministry of finance is studying the responsibility of government contract payment into the budget management and interim financial planning of the government, which will solve the problem that social capital is worried that the government's responsibility to pay is not in place.

In addition, relevant documents, guidelines and guidelines will be developed to enhance social capital confidence and future projects.

The time between signing and landing will be greatly reduced.

The concept of global technology innovation center was first put forward by wired magazine.

The China Financial Information Center report believes that the technological innovation center with global influence is the source of global innovation resources, and is the original place of innovative ideas and innovative technologies, and can achieve efficient pformation in the local area.

The innovative products and innovative industries that it breeds has an obvious driving effect on the economic development of the surrounding areas, and can represent the country or a region to participate in global competition.

At present, Silicon Valley, Munich, Tokyo and other technological innovation centers and innovative cities have been formed worldwide.

Among them, the Silicon Valley model has become the object of competition in China.

The data show that the Silicon Valley mode is mainly guided by the enterprise's independent innovation of the whole society, combined with the efficient combination of production and learning, perfect venture capital system and good social division of labor.

It is reported that in the first quarter of 2014, 50% of US venture capital funds were invested in Silicon Valley.

Munich, Tokyo and other places are different in specific innovation models, or rely on local university resources or jointly promote technological innovation by the government and enterprises, but the whole society has created a new situation.

At home, Beijing, Shenzhen and other places are scrambling to promote technological innovation.

Data show that in 2014, Beijing research and development expenditure was 128 billion 660 million yuan, equivalent to 6.03% of GDP, ranking first in the country.

Between 2008 and 2014, the added value of scientific research and technology services in Beijing increased by 11.5% annually, and the value added of information pmission, software and information technology services increased by 10.9% annually.

Last year, Shenzhen research and experimental development funds amounted to 64 billion 330 million yuan, equivalent to 4.02% of GDP.

Shanghai faces both international and domestic pressures on technological innovation.

The 2014 global innovation city index released by the Australian think tank shows that Shanghai's ranking in the world's 445 evaluated cities has dropped from twenty-ninth in the previous period (2012-2013) to 35, and the trend is not very optimistic.

Statistics show that in 2014, expenditure on research and development in Shanghai amounted to 83 billion 100 million yuan, equivalent to 3.6% of GDP.

Despite the huge increase in funding for research and trial development in Shanghai in recent years, Shanghai should pursue higher goals in the era of innovation.

Last year, the senior executive suggested that Shanghai should enhance its core competitiveness and truly implement technological innovation to industrial development.

Subsequently, the construction of Shanghai science and technology innovation center has gone through more than six months of research and internal research, and has been a major issue of Shanghai Municipal Committee No. 1 in 2015.

Han Zheng, Secretary of the Shanghai municipal Party committee, defined the construction of the science and technology center as "the fundamental measure to break through the bottleneck of development and reconstruct the driving force for development".

Shanghai welcomes the new orientation of "fifth centers".
