It is important to optimize the cooperative innovation network for the improvement of economic competence and innovative power. Based on the patent information services platform, we obtain invention patent data for the electronic information industry in Liaoning from 1985 to 2015. This paper analyzes the cooperative innovation network structure, its spatiotemporal evolution and the triple helix relationship of government-industry-university (GIU) by using the social network analysis method and the triple helix theory as well as UCINet, ArcGIS and NetDraw. The empirical results show that: 1) the number of the subjects of the electronic information industry GIU cooperative innovation network in Liaoning demonstrates a gradual increase from 1985 to 2015, with the same trend in concentration. In terms of its subject and its centrality, the universities have a higher position, and the industries have a lower position, while the status of the government is still unclear. 2) The cooperative innovation network presents a core-periphery structure, and the polarization effect of innovation subjects tends to be obvious. There is certain distance-decay regularity in the cooperative innovation network, and a strong geographical proximity to cooperative innovation. 3) The compactness shows a downward trend as a whole. In terms of the extent of participation, the industries are better than the government but worse than the universities. This means that the cooperative innovation network of GIU in the electronic information industry in Liaoning is in the initial stage of formation.

A data envelopment analysis cross-efficiency model was used to measure the innovation efficiency of Chinese intelligent-manufacturing (IM) enterprises. This paper took as samples the number of granted patents and R&D investments of IM enterprises listed from 2015 to 2020. This research used the modified gravity model to determine the innovation efficiency and the spatial correlation of IM enterprises in China and used UCINET software to reveal the innovation efficiency and spatial network characteristics of IM enterprises through a social network analysis. The study found that the relationship was significant and frequently close between innovation efficiency and the spatial correlation network of IM enterprises. The distribution of the spatial association network was “core-edge,” and IM enterprises in Eastern China were at the network core and mostly played an intermediary role. The spatial correlation network had four modules. The distribution of the enterprise innovation correlation was uneven within each module, amalgamation was poor among the subgroups, and characteristics of highly cohesive subgroups were present.

China proposes that supply-side structural reforms should be carried out in the context of serious contradictions and problems such as overcapacity and serious contradictions of upgrading of demand structure, and insufficient inner motivation for economic growth. From the perspective of short-term supply and demand management and long-term supply and demand management, this paper analyses the theoretical basis of taxation system arrangement under supply-side structural reform, construct the method of assessing the impact of taxation system under supply-side structural reform. From the perspective of supply-side structural reform and the construction of innovative taxation governance system, this paper puts forward policy suggestions on tax system arrangement under supply-side structural reform. Theoretical Basis of Taxation System Arrangement under Supply-side Structural Reform Say's law: In 1803, F rench economist J.B.Say proposed that in the two exchange modes of exchanging product for money and money for products, the role of money is only momentary. After the transaction, the transaction is to exchange one kind of goods for another kind of goods. For either the seller or the buyer, supply creates demand. Keynesian law:In the 1930s, the Great Depression broke out in the major capitalist countries of the world, the phenomenon that supply could not create demand on its own was gradually emerging. Keynes believes that under the combined influence of diminishing marginal propensity to consume, diminishing marginal efficiency of capital and rising interest rates caused by liquidity preference, aggregate demand will be insufficient and the economy will decline. He also believes that in response to the economic recession, governments should manage aggregate demand, and conduct expansionary fiscal and monetary policies to stimulate aggregate demand. Theory of Supply-side Economicsl: In the early 1970s, stagflation generally occurred in developed capitalist countries. On the one hand, economic development stagnated, while on the other hand, prices was rising continually. The usual demand management tools of governments have encountered an unprecedented dilemma, at that time, supply-side economics proposed their theory. Supply-side economics believe that the lack of supply is caused by excessive intervention of governments in economy and excessive tax burden. Therefore, in order to cope with stagflation, it is necessary to replace demand management with supply management, and to stimulate aggregate supply by reducing intervention of governments in the economy and drastically reducing tax burden.
