It makes the conclusion that FDI in different areas has different technological spillover effects and the local governments should make different policies accordingly so as to gain more obvious technology spillover effects.展开更多

By building a parametric cost frontier model using panel data, this paper investigates the drivers of economic growth transformation from a cost perspective. According to our research, among various effects triggering corporate cost variations and in addition to the expansion of production scale, the largest effect is from technological progress, followed by the effect of factor price adjustment and the effect of efficiency gains. Within the decomposition of factor price adjustment effect, the energy factor effect is the most significant. Furthermore, energy price fluctuations are likely to become major factors restricting saving-based growth. Further study reveals that both the ownership reform and opening up of SOEs are favorable to reducing the costs generated by inefficiency. This paper provides empirical evidence for the driving mechanism of saving-based growth transformation as well as empirical evidence to support to the further deepening of property rights and market-oriented reforms.展开更多

As health economic considerations get into focus in terms of business planning and reimbursement, valid and flexible economic feasibility studies get more important. Unfortunately, literature mostly provides only single economic views on specific aspects like cost savings from reduced rehabilitation in a special patient cohort. To make planning and technology value negotiation more effective and more valid, a methodology to collect relevant data from different studies and normalize it to a common set of parameters was developed for the field of cardiac monitoring in a mixed example population with an approach of simple external weight, ECG and blood-pressure measurement or implanted devices for cardiac monitoring. The target entities taken into account by the simulation model were the impacts on heart attack, stroke, heart failure and the process of implant monitoring. Simulation took place at an example population of 500 patients with specific morbidity criteria. The health economic value was calculated over a period of three years and was split into a technology effectiveness measurement in Quality-adjusted-Lifetime-Years (QALYs) and a “cost- saving-part”. QALYs were chosen as technology effectiveness parameter for a combined and weighted mortality- and morbidity-reduction. Allocating 24.000 Euro to a saved QALY, 42% of the cost would be allocated to QALYs meaning money being spent for gained lifetime-years. The remaining 58% would be the different real cost savings: a per patient gross saving of 3.308 € per year would result for that part (21% on heart attack, 3% on stroke, 68% on heart failure and 8% on implant monitoring). Up-to-date studies do not provide a simple mechanism to allow custom-tailored health economic feasibility study results in terms of other specific population mixes or outcome parameters. Target audiences for the methodology of the described simulation are payors and solution providers targeting a specific patient population or specific telemedical situations. This way product development can address market-related needs more specific and healthcare providers can compare different outcome parameters in the given entities.展开更多

The empirical analysis shows that inter-industry technology spillover has a significant positive effect on the labor productivity of each industry. The elasticity of productivity effects of inter-industry technology spillover is not only larger than that of direct R&D input, but also increases over time. We group the industries into four major categories and find that the inter-industry technology spillover effect within the categories is, on average, greater than that between the four categories, indicating that technology spillover occurs more easily between similar industries. This research shows that the interindustry technology spillover effect in China has begun to increase, and the government should take advantage of this effect.展开更多

Applying KBM Asympto-tic method, the vibration of the system in case of weak semi-active control is studied. ln pcactice, there are two types of vibration isolation. One is to isolate the transmitting of the cyclicunbalanced force generated by the revolving machine to the surroundings. The other is to isolatethe transmitting of the vibration displacement of the surroundings to precise equipment. Deduc-ing the influence of the roadway unflatness on vehicles also belongs to this type. For the firsttype of isolation system, the damper always dissipates energy, and the total work done by the spring in a vibration cycle is zero. For the second type of isolation system, the work done by the damper sometimes is positive, and sometimes negative. The damper dissipates less energy. The work done by the spring in a vibration cycle isn't zero, and it is usually positive. ln thispaper, the vibration isolation is refered to the second type. .展开更多

Under the constraint of the production possibility frontier, there is either complementarity or substitutability between domestic and foreign trade. It must be decided whether resources should be concentrated in one of the sectors (trade specialization) or instead allocated equally (trade equalization) between the two sectors. This paper firstly discusses how domestic trade and foreign trade work together to influence technological innovation, and how trade equalization and specialization affect different types of innovation. Using a provincial-level panel dataset from 2007 to 2015 in China, this paper constructs the indicators of domestic and foreign trade linkage and examines the impact of trade on innovation. The findings show that trade equalization mainly promotes incremental innovation, while trade specialization improves radical innovation. Thus, in the area of incremental innovation, attention should be paid to the equalized development of domestic and foreign trade, while in areas pursuing radical innovation, emphasis should be put on the specialization of the trade sector, avoiding equal allocation of resources to the two sectors.展开更多
