| In the era when the degree of global knowledge economy gets increasingly profound, technological progress has become the main driver of economic progress and significant field of comprehensive national competition in major developed countries, and even for the whole world thanks to its characteristics of increasing returns to scale. Although China has experienced rapid development in high-tech industry, there are still challenges from home and abroad. As China now is in a critical period of the economic growth mode transformation and industrial structure adjustment, it is an important tasks for the country to develop high-tech industries, and encourage high-tech industrial enterprises to enhance innovation ability in order to construct an innovative country. Compared to traditional industries, because high-tech industries are less constrained by natural conditions but highly dependent on knowledge and technology, their type of space layout mainly takes on the form of industrial clustering due to their needs for the dynamic externalities of knowledge and technology spillovers. In the early development phase of high-tech industries, regional specialization helps to promote labor productivity in regional industrial clusters. Because of the conspicuous inter-regional differences of high-tech industry development in China, the unique characteristics of high-tech industrial agglomeration and regional specialization in specific areas, as well as the large spatial dependence of regional high-tech industry output, it is useful for us to better understand the distribution of high-tech industry and regional development in China to study the effects of factor inputs, the degree of industrial concentration and specialization areas on high-tech industrial output under the spatial frameBased on related theories of industrial and regional economy, this paper first measures degrees of high-tech industrial agglomeration and specialization in each province, and finds out that the spatial layout of high-tech industry in China has undergone profound changes during the study period:the diffusion phenomenon from the developed provinces to less developed provinces is obvious in the eastern region, while; the degree of concentration of in the western region has seen an overall downward trend, which leads to an the expanding gap between other regions; high-tech industry center-east region of clear division of labor, in some regions where the central province has a rich high-tech industrial structure and surrounded by other provinces with higher degrees of specialization, there has formed clear division of labor; single structure of high-tech industrial development causes high level of specialization in western provinces.Then after a series of tests, this paper integrates the degree of industrial agglomeration and specialization as two indicator two indicator C-D production function to examine their influence on high-tech industrial output in each provinces n the space neighboring rights spatial Durbin model (SDM), together with inputs of capital and labor factors inputs. The results are as follows:the labor input produces a positive a direct effect on regional output but a negative spillover effect, while the negative effect is less than the positive effect on the adjacent regions, which result in a positive total effect; fixed assets investment in the region only has a positive direct effect; industry agglomeration for local and neighboring regions has both very significant promoting effects, while specialization weakly inhibit output in both local and adjacent areas. According to the conclusions and objective situations of different regions, this paper put forward proposals in order to promote the development of high-tech industry. |
