Abstract: Under the low carbon economy, this paper studies the relevant factors that affect the modern manufacturing industry in Beijing during the past ten years. This paper draws the following conclusions: (1) The innovation capability of Beijing modern manufacturing industry is constantly improving. The innovation capability of electronic equipment manufacturing industry (computer, communication, etc.) is higher than that of other industries and the transportation equipment manufacturing industry (Railway, ship, aerospace, etc.) and automobile manufacturing industry also play an important role in innovation. (2) In terms of the influencing factors of innovation capability, the investment of scientific research funds is the most important factor to improve the innovation capability of modern manufacturing industry in Beijing. The input of scientific research personnel, i.e. labor force, will also play a positive role in promoting innovation capability, but energy input will have a negative impact on innovation capability, and the impact is significant. Based on the above conclusions, this paper puts forward some countermeasures to improve the innovative ability of modern manufacturing industry in Beijing under the low-carbon economy, including increasing investment in scientific research funds and scientific and technological personnel. By doing so, energy consumption intensity can be reduced, and energy-saving technology are greatly developed. Further, low-carbon development, and the industrial structure of modern manufacturing industry in Beijing is optimized and low-carbon economy is achieved.
In view of the above research conclusions, we put forward in this paper the following strategies in upgrading the innovation capability of Beijing modern manufacturing industry:
Firstly, the government and enterprises should continue to increase investment in scientific research, especially in basic and strategic research. At present, the R&D expenditure of modern manufacturing industry is not adequate, and investment will become an important factor restricting the independent innovation of modern manufacturing enterprises in Beijing. Inadequate input will inevitably affect the output of independent innovation.Lack of independent intellectual property rights will inevitably lead to lack of research and development of new technologies and products in modern manufacturing industry. The research finds that the investment of scientific research funds contributes most to the growth of industry innovation production capacity. Strengthening investment in scientific research is helpful to transformation of modern manufacturing industry, introduction of technology, improvement of digestion and absorption capacity, and can actively promote the technological progress of modern manufacturing industry.
Secondly, Beijing’s modern manufacturing industry needs to focus on low-carbon development, vigorously develop energy-saving technologies, and constantly reduce the intensity of energy consumption. The low-carboncapability of Beijing modern manufacturing industry is the key to the technological progress and market competition and, therefore, create new competitive advantages. In recent years, the total energy consumption of Beijing’s modern manufacturing industry has declined significantly. Traditional manufacturing industry has been the main energy consumer of manufacturing industry, but its proportion of energy consumption has decreased. The total energy consumption of modern manufacturing industry has an upward trend, but the overall energy consumption efficiency has raised.
Thirdly, we should further increase the input of scientific and technological talents and build up a team of high-tech talents in Beijing’s modern manufacturing industry. The essence of innovation drive is the talent drive. In 2016, the total number of scientific research personnel in modern manufacturing industry accounted for more than 80% of the total manufacturing industry. With the increase of scientific research personnel in various industries, it is necessary to further increase the investment of high-tech personnel in modern manufacturing enterprises, especially first-class high-tech talents, create incentive policies for scientific research personnel, and stimulate the enthusiasm and creativity of all kinds of talents.
Finally, we should optimize the industrial structure of Beijing modern manufacturing industry and give priority to the development of high-end intelligent computer communication equipment. On this basis, build Beijing modern intelligent control and intelligent manufacturing system, give play to the radiation driving role of the industry. Further, we should accelerate the construction of industry informatization, and transform modern manufacturing industry with information technology, and reconstruct industry value chain and whole business chain with Internet thinking. By upgrading the investment structure and eliminating backward production capacity, the industrial structure can be optimized, the investment of enterprises which is highly dependent on resources and technology with low content and relatively serious pollution will be gradually reduced, the investment and R&D investment in technology-intensive industries, especially in high-tech industries, will be increased, and high-end products will be developed to promote industrial technological upgrading.
The above conclusions are developed by using the improved Cobb Douglas production function to analyze the influencing factors of Beijing’s modern manufacturing innovation capability under the low-carbon situation. We expand the research perspective of manufacturing innovation capability evaluation, which has theoretical and practical significance to guide China’s modern manufacturing industry regarding the improvement of its innovation capability under the low-carbon situation. However, there are still some deficiencies in the study of specific measures to further enhance innovation capability. In our future work, the scientific decision-making basis of innovation capability and low-carbon development capability of modern manufacturing industry in Beijing will be thoroughly studied by using model simulation method, and the decision-making optimization model of low-carbon development of modern manufacturing industry in Beijing will be constructed to carry out mid-and long-term simulation, in order to put forward reasonable and feasible development path and implementation plan.
