In order to promote the coordinated development of industrial structure towards manufacturing industry and producer services and improve the level of regional economic development, the "double-wheel drive" development mode of modern service industry and manufacturing industry in developed regions or countries is studied, and the economic effect of the collaborative agglomeration of producer services and manufacturing industry is studied. The most basic economic effects of industrial collaborative agglomeration are economic growth effect and industrial structure upgrade effect. The Yangtze River Delta urban agglomeration must reasonably promote the "two-wheel" driving strategy, change the mode of economic development, relieve the crowded effect of industrial collaborative agglomeration, and transform the negative effect of industrial collaborative agglomeration on economic growth. This study has reference value in the following aspects: to ease the spillover conduction path of industrial collaborative agglomeration, to strengthen the coordinating and leading role of central cities, to accelerate industrial upgrading, and to narrow the regional income gap.

Capital Intensive

This paper, through examining the emergence and evolution of industrial structure in China's automotive industry, have attempted to assess the degree to which the country has succeeded in restructuring the overly fragmented and dispersed pattern of industrial organization in a capital-intensive industry featured by high economies of scale, the loss in economic efficiency due to fragmented structure of which is therefore greater. The result of the analyses shows that the fragmented industrial structure that emerged during the Cultural Revolution period, populated by numerous firms of sub-optimal scale that are scatted in all but a few regions of the vast country, have not only persisted throughout the reform era but in fact has become more fragmented both in terms of lower concentration ratios at firm level and greater geographical dispersal of production. Although there exist some signs of gradual progress in consolidation at the level of enterprise groups, the real economic effect of such restructuring, however, seems to be quite limited due to the lack of effective coordination and integration of operation between affiliate automakers nominally under umbrella of the same group.

Feeding Systems

Effective application of slag-forming mixtures (SFM), being fed into continuous castingg machine (CCM) moulds, depends on their even distribution on the melt surface. Manual feeding of the SFM which is widely usedd does not provide this condition, resulting in the necessity to actualize the work to elaborate systems of SFM mechanized feedingg into moulds of various types CCM. A concept of the designing of a system of SFM feeding into CCM moulds presented with the ratte strictly correspondent to the casting speed and providing formation of an even layer of fine material of given thickness on the whoole surface of liquid steel. The proposed methods of designing of the SFM mechanized feeding systems based on three-dimensional computer simulation with the subsequent verification of the correctness of the adopted technical solutions on field samples. Informattion is presented on the design features of the adjusted facilities intended for continuous supply of finely granulated and powder mixtuures on metal mirror in moulds at the production of high-quality billets, blooms and slabs. Variants of mechanical and pneumo-mechaanical SFM supply elaborated. At the mechanical supply the fine material from the feeding hopper is moved at a adjusted distance bby a rigid horizontally located screw. At the pneumo-mechanical supply the metered doze of the granular mixture is delivered by a sshort vertical screw, the lower part of which is located in the mixing chamber attached from below to the hopper and equipped with ann ejector serving for pneumatic supply of the SFM in a stream of transporting gas. It was proposed to use flexible spiral screws in the ffuture facilities of mechanical SFM feeding. It will enable to eliminate the restrictions stipulated by the lack of free surface for locatiion of the facility in the working zone of the tundish, as well as to decrease significantly the mass of its movable part and to decreaase the necessary power of the carriage moving mechanism driver. The novelty of the proposed technical solutions is protected by thhree patents. The reduction of 10–15% in the consumption of slag-forming mixtures during the transition from manual to mechanizeed feeding confirmed. The resulting economic effect from the implementation of technical development enables to recoup the costs inncurred within 8–10 months.

International Capital Movement

The paper deals with the past, current and future situation in Russian capital outflow and inflow. The specific features of the past situation (2001-2013) were as follows: big scale of Russian participation in international capital movement; turnover of national capital between Russia and offshores; stable surplus of capital outflow over inflow; inadequacy of industrial structure of capital inflow to Russian needs. The current situation is characterized by such new features as radical cut in volumes of capital outflow and inflow, some decrease in its level of offshorization. In the mid-term the probability of continuation of current trends is high. In the long-term the mode of Russian participation in international capital movement will prima facie depend on prospects of realization of systematic reforms in the Russian economy.

Primary Frequency Control

The paper gives the analysis of the problem of the primary current frequency regulation in the power system, as well as the basic requirements for NPP power units under the conditions of involvement in the primary regulation. According to these requirements, the operation of NPPs is associated with unloading and a corresponding decrease in efficiency. In this regard, the combination of nuclear power plants with a hydrogen complex is shown to eliminate the inefficient discharge mode which allows the steam turbine equipment and equipment of the reactor facility to operate in the basic mode at the nominal power level. In addition, conditions are created for the generation and accumulation of hydrogen and oxygen during the day, as well as additionally during the nighttime failure of the electrical load which allows them to be used to generate peak power.  The purpose of the article is to assess the systemic economic effect as a result of the participation of nuclear power plants in combination with the hydrogen complex in the primary control of the current frequency in the power sys-tem, taking into account the resource costs of the main equipment. In this regard, the paper gives the justification of cyclic loading of the main equipment of the hydrogen complex: metal storage tanks of hydrogen and oxygen, compressor units, hydrogen-oxygen combustion chamber of vapor-hydrogen overheating of the working fluid in the steam turbine cycle of a nuclear power plant. The methodological foundations for evaluating the working life of equipment under cyclic loading with the participation in the primary frequency control by the criterion of the growth rate of a fatigue crack are described. For the equipment of the hydrogen complex, the highest intensity of loading is shown to occur in the hydrogen-oxygen combustion chamber due to high thermal stresses.  The system economic effect is estimated and the effect of wear of the main equipment under cyclic loading is shown. Under the conditions of combining NPP power units with a hydrogen complex, the efficiency of primary reg-ulation is shown to depend significantly on: the cost of equipment subjected to cyclic loading; frequency and intensity of cyclic loading; the ratio of the tariff for peak electricity, and the cost of electricity of nuclear power plants.  Based on the developed methodology for assessing the effectiveness of the participation of nuclear power plants with a hydrogen complex in the primary frequency control, taking into account the damage to the equipment, the use of the hydrogen complex is shown to provide a tangible economic effect compared with the option of unloading nuclear power plants with direct participation in frequency control.
