In recent years, the bottleneck technology problems have become more and more in the high-tech industries of China. These problems suggest the serious problem of systematic defects in the innovation system of China. Industrial generic technologies belong to the fields of applied basic research, and they are always multidisciplinary technology integration. This kind of technologies needs to be accumulated and cultivated in a long-term. In the developing countries, it is very important to build many high quality research institutes of industrial generic technology, which should focus on the development of key generic technologies, and they will bridge "the valley of death" in the innovation system, promoting the technology upgrading of the regional industry.

With the new development pattern, the popular exploitation of scientific and technological resources provides a new path for the integration of science, technology and economy. China's relatively rich scientific and technological resources play an intrinsic role in promoting the economic development and the industrial transformation. The rational allocation, the function expansion and the effective transformation of scientific and technological resources are the key to promote the integration of science, technology and economy. The popular exploitation of scientific and technological resources can play an important role in optimizing the allocation of public resources, communicating science to the public, promoting the integration of science, technology and economy, and promoting supply-side structural reform. Meanwhile, there are still obstacles, including the lack of policy support, the insufficient motivation of scientists, the poor channels for popular exploitation and the lack of integration with industry. The paper proposes to provide the policy supply, the dynamic mechanism, the cooperation channel and the resource network for the integration of science, technology and economy by a top-level design, by creating a good ecology, improving the financial security and expanding the communication channels and forming industrial clusters.

In the context of the development of the engineering equipment industry in Shandong Province and Jining City, with the experience of the construction of machinery intelligent equipment innovation and entrepreneurship community as an example, this paper analyzes the importance of the construction of the industrial innovation and entrepreneurship community, and puts forward the operation mode, the existing problems and the construction experience of the industrial innovation and entrepreneurship community from different perspectives around the integrated layout of the innovation chain, the industry chain, the talent chain and the financial chain, focusing on the important responsibility and the role of the innovation and the entrepreneurship community in guiding the industrial development, organizing the enterprise collaborative innovation, and strengthening the industrial cluster of the whole province.

The agricultural economy, the industrial economy and the digital economy are three social development stages. In the digital economy era, the new generation of information and communications technology (Big Data, AI+, IoT) drives the productivity in a rapid development, and the relations of the production become more transparent and fairer. The continuous optimization of the efficiency, the quality and the structure of the supply system has a great impact on the demand system and the social governance system. From the angle of the productivity and the production relation, by comparing the digital economy with the agriculture economy and the industrial economy, this paper reviews the reforming trend of the supply and demand system and the development direction of the social governance system in the era of the digital economy, to provide a reference for China to build a new supply system for a high-quality economic development. It is indicated that the digital economy is one of the key factors in promoting China's supply system especially in building the smart productivity and the transparent, fair and efficient production relations. Beyond that, China has to be prepared to go from macro to micro, for the application of the technological innovation, the management mode optimization, the governance system reform and other aspects to benefit under the digital economy.

With the rapid development of the cross-border e-commerce, the corresponding cross-border payment shows a multi-channel, multi-mode and high-frequency nature. The practice of the cross-border e-commerce payment sees several risks from time to time, such as, in credit, interest rate, exchange rate and law. However, these "cross - border" payment risks have not been paid adequate attention in the academic literature, in particular, without in-depth researches on these risk formation mechanisms. With the help of the credit risk theory, combined with the analysis of the specific situations, the relationships and the practices of the cross-border e-commerce payment, this paper systematically discusses various formation mechanisms of the credit risk of the cross-border e-commerce payment, and outlines a three-dimensional picture of the occurrence logic of the cross-border e-commerce payment credit risk.
