| Regional economic development is a process of production essential accumulation, combination and increment in given range. As the carrying of activity and production for people, land is special resource in fact. Regional economic development has to repose on the actual space, and it is unimaginable for regional development disengaged land support. Push industrial structure adjustment and optimization is the topic of regional development. Allocation effect of scarce resource is decided by industrial structure on a certain extent. Sometimes, land use structure is the special reflection of industrial structure. Actually, land resource is used by different industries, and then their production is largely different. With rapid economy development, it is difficult to extend the space for industrial development with land extensive use. Promoting land intensive use will be the main aim of regional land use. The mode, structure and change of land use lies on industry development and industrial structure evolvement. On the other side, the state, endowment, mode, policy of land use also can induct and restrict regional industrial development and the way of structure adjustment. Above all, there is conesponding relation between regional industrial structure and land intensive use. The paper will start from the relation between industrial structure and land use, and deeply discuss the mutual influence of regional industrial structure adjustment and land intensive use. Designing land intensive use policies to be one way of macroeconomic regulation and control induct and inhibit regional industrial structure adjustment through the level of land use intensive. Pursue to actualize the strategy of regional industrial structure adjustment advancing land intensive use. Realize the aime of land sustainable use and social and economic sustainable development. Be the bottom for harmonious society.Firstly, the objective & research background, theoretical framework & technique route, research objective & contents, research methods & sources of data used are introduced. The literature of domestic and abroad is reviewed and commented also. Then the definition and connotation of land intensive use is confirmed, and some relative concepts are distinguished. Also the connotation of region and industrial structure adjustment in this paper are explained. As research theoretical basic, land scare, rent & land-value, location, reward descending and sustainable development theories are reviewed and concluded.Since the complexity of regional industrial structure and land intensive use respectively, according to the common theory and evolvement rule of industrial structure, judge nowadays industrial development of China is on the stage of prophase and middle. Then analyze the mutual relation of industrial structure evolvement and land use change, and point out that limited land resource is not only the basic cattier also the space restriction. Industrial structure adjustment is direct drive to land use structure evolvement and influence the mode and layout of land use. Meantime, the distributing characters and production efficiency of industries would be restricted and influenced by the mode and degree of land use, and also various functions of land use would change. Emphasize the different stages of industrial development, and people exploit and use land resource has distinct age remarks. In China's development stage, land also is the important factor in economic development. The substitute rate of land and capital is gradually reducing, and it indicates that land intensive use is necessary trend with industrial structure adjustment. Recent years, the fact can verify it that China's land use mode from extensive use to intensive use. But since there are some problems such as the conflict of people and land, land use low efficiency, and deep sticking points like market and legal system faultiness, useless or inefficient control of government in China's transfer period. Judge that in certain future time, the stage of China's land use mode would still be a transfer period with extensive use and intensive use, but extensive use is still the main mode. It supports the necessary research visual angle, scope and logic basic to study on the influence of regional industrial structure adjustment to land intensive use.Paper analyzes the mutual influence mechanism and approach of regional industrial structure adjustment and land intensive use on theory and demonstration. Regional industrial structure adjustment is change and mergering of regional industrial distribution on geography. The effect of department allocation is the main way to improve the level of land resource intensive use with industrial structure adjustment. The character of reginal industrial structure decides convergency and radiancy of land and other factors. The benefit of scale and convergency reasonably promotes land intensive use. According to the analysis of market economic law, investment and output on land would change with the adjustment and layout of regional industrial structure. Internal value mechanism could induce the mode to land intensive use. So regional industrial structure adjustment could improve benefit and intensivism of constructive land, and be propitious to optimize land use structure. The result is layout like circles of regional industrial land. From the analysis of single indicator, there is the relation of distinct direct proportion between industrial structure change and land intensive use in China. That is the level of land intensive use will increase about 9% with 1%increase of the proportion of adding value on second & third industries in GDP. But population increase, economic increase, technology advancement, government control and the allocation level of land market are all important influence factors to industrial land intensive use. The analysis framework supplies the theoretic basic for farther quantitative analysis on land intensive use and industrial structure adjustment in China.Land intensive use has the counter force to regional industrial structure adjustment. Regional industrial structure is based on the factors such as land, human resource, capital and technology. The use mode and degree of land resource decide the structure and layout of regional industries. And pursuing benefit maximum is the internal drive whatever regional industrial structure adjustment. The effects of land supply and demand, cost and benefit of land use, land rent and location have distinct influence to regional industrial structure adjustment. Investment capability and output efficiency of different industrial land are different and dicide different level of land intensive use, then arise the change of regional industrial structure. The research aim of influence of land intensive use to regional industrial structure adjustment is service for design land use policy. But combining the detail situation of our country, market mechanism is the base to allocating land resource and government control is the complementarity. It is good to reasonably use land resource and improve land resource sustainable use. Also the action boundary of government must be limited.For answering how to influence and the indicating gist, paper handles the panel data, modeling and analyzes regional difference. According to compare dominance theory and proper model simulate the compare dominance of industrial land in China's east, middle and west regions. Then emphasize on the appraisal and compare analysis on land intensive use of the main industrial enterprises, for researching industrial land allocation and industries internal structure adjustment. Main conclusions are put forward as follows:(1) The influence of regional industrial structure adjustment to land intensive use is distinct and regional difference. The influences of second and third industries are both obvious. Comparatively, the influence of second industry is more. Meanwhile, different regions the influence is different. The influence in east region is most prominent, and in west region is lowest. It indicates that some region has the more developed second and third industries, and the higher level of land intensive use, and then adjustment of industrial structure would benefit to improve the level of land intensive use. From development trend, the elasticity coefficient of second industry in east region is higher than average level of China, and middle region is at the same level with average level, and the coefficient in west region is lower than average level. It is obvious grads, especially in middle and west regions, and the position upgrade of second industry will improve the level of land intensive use. The influence of third industry is a bit lower, especially in west region, but there is great potential of third industry pull the level of land intensive use increase with relative position change between second and third industries.(2) The influence of land intensive use to regional industrial structure adjustment is distinct and regional difference. The compare dominance of industrial land intensive use is the gist for regional industrial structure adjustment. The result of measurement for three economic regions indicates: the efficiency of the first, second and third industrial land intensive use all have compare dominance in east region; the efficiency of the first industrial land intensive use has compare dominance in middle region; the efficiency of the second and third industrial land intensive use has compare dominance in west region. So according to above compare dominance, plan the overall arrangement of industrial land and design region harmonious strategy tropism of industrial structure for improving land intensive use. The aim of industries transfer is gradually building a main superseding zone of national energy sources and mine sources in west region; building an important base of modern transportation and agriculture in middle region; developing high technical industries and modern service industries in east region, and enhancing the admittance threshold of labor intensive industries, and promoting traditional industries to transfer to middle and west regions. And land intensive use policy is the effective way to realize above aim.(3) The structure adjustment of the second internal industries would combine the level of land intensive use for optimizing industrial structure and overall arrangement and improving industrial land intensive use. Compared with the mode of economic increase, in the future recent years, the mode of land use in Jiangsu province would be in a transfer phase with extension expanding and intension advance. The results of investigation for main industrial enterprises land indicate: according to the level of different industrial land intensive use, electronic and other high & new technical industries would be encouraged to develop, and delicatessen, weave, engine, light industries would properly develop in the south of Jiangsu province; some industries with compare dominance such as building material, electric power, metallurgy, weave, and chemical industries would develop in the middle of Jiangsu province; delicatessen, medication, engine, and chemical industries would be the important developed industries in the north of Jiangsu province. More space for industries upgrade and development would be vacated in the south of Jiangsu province through industries transfer, etc. and pull rapid development of industries in the middle and north of Jiangsu Province.But above research results cannot answer how to put the though of land intensive use into the strategy of regional industrial structure adjustment. It needs the policy design of land intensive use. It still is relatively shortcut and effective method depending on policy to realize that land acts on macroeconomic adjustment and control for inducting industrial structure adjustment. From the experiences of theory and domestic and abroad, land intensive use policy can induct the direction and process of industrial structure adjustment, and it is propitious to optimize regional industrial structure and overall arrangement. Mode transfer of economic increase and the phase of regional industrial development would be combined in designing the policy. Also industrial policy would be matching. Regional industrial structure would improve to change to more reasonable upgrade through resource allocation reform, government function transformation, successful mode extended and policy innovation. Form a policy system of land intensive use, including stronger land property right management, better land market system, perfect land tax and fee policy, cooperating regional industrial policy, building regional cooperative mechanism and strengthening dynamic intendance on land use. Industrial land threshold is a policy innovation combined with land intensive use and regional industrial structure adjustment. Because of pertinency and complexity of the policy designing on industrial land threshold, paper would concretely innovates policy on regional land intensive use through the analysis results of demonstration in Jiangsu province. According to industrial development strategy in Jiangsu province and the results of analysis on industrial land intensive use, this paper chooses the key industries in different regions in Jiangsu province and designs three industrial land threshold in term of region division and industries partition, and they are building capacity rate threshold, investment intension threshold and land output threshold. It can make a strategy of regional industrial structure adjustment based on the level of land intensive use and supply the guidance for industrial development and land use in different regions of Jiangsu province.Lastly, paper shows the important conclusions of this research and proposes some advices for the continuous studies.
