# Introduction uangzhou is an important manufacturing city in southern China. The manufacturing development not only speeds up the development of industrialization, but also becomes hard nucleus of economic sectors in Guangzhou after the reform and opening in China. However, the changes of economic environment in domestic and overseas lead to a series of problems loom large. Such as the cost of resource and environmental pressure are growing rapidly, structural shortage of labor is increasingly serious, the original labor costs and regional comparative advantage has been disappeared, the low level of industry, the lack of innovation and constraint of resources and environment in economic development. Therefore, it is a matter of Guangzhou's economic future to promoting the adjustment of manufacturing structure further. On that account, the article attempts to discuss the adjustment problems of manufacturing structure in Guangzhou based on the Dynamic Shift-Share Method. The changes of the manufacturing structure in Guangzhou are chosen as the research objects in this paper. Firstly, the dynamic DSSA econometric model has been introduced and it collects the relevant data during 2001-2011. Secondly, it carries on the quantitative empirical analysis of industrial structure, and then discusses Guangzhou's main dynamic changes of manufacturing structure. Lastly, the transformation with the strategy of speeding up structural adjustment and upgrading the manufacturing structure in the future are given. According to the DSSA model, the article analysis the dynamic data based on Output Value of Main Industrial above the Designated Size. All the data in the article comes from the GUANGZHOU TATISTICAL YEARBOOK (2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012). Through preprocessing the data and converting it to constant prices of industrial production in 2001, the article obtains the table of output Value of the main manufacturing industry (table 1). The above empirical analysis shows that remarkable results had been achieved on restructuring work of manufacturing in Guangzhou during 2001-2011. For example, it is mainly represented by the content of manufacturing and categories of leading industry have a fundamental change and the industrial structure has a rationalization and sophistication direction. On the other hand, proportion of advanced manufacturing has risen continually, overall size has increased considerably, and competitiveness has improved rapidly, that showing a good momentum of development. But these results are just beginnings. For various challenges caused by environmental changes, the rapid growth of the manufacturing has been faced the ceiling limit, and the marginal benefit has begun declined by using the original method of structural adjustment. # II. The Change Analysis Combined the above analysis with the current trend of the development of global manufacturing, it is necessary for manufacturing to convert the direction of industrial restructuring in Guangzhou. This is the only way that we can accelerate the pace of structural adjustment and improve the quality adjustment. According to current stage of economic development in Guangzhou and constraints of various factors, resources and environment, the article indicates that restructuring industry must transforms relying mainly on investment attraction and capital investment into focusing on innovation to improve the efficiency and high of industrial structure. Meanwhile, restructuring industry should promote the Guangzhou manufacturing from a labor-intensive and low value-added type to technology-intensive and high value-added type. According to the basic theory of spatial economics, it is obviously that Guangzhou has geographical advantages for the development of manufacturing industry. At the same time, mercantilist history and the policy of reform and opening making software and hardware environment of Guangzhou manufacturing both taking the lead. This may account for Guangzhou becoming the developed areas of domestic manufacturing from a weak region before the time of reform and opening. Nevertheless, it should be noted that many domestic regions such as Shenzhen, Tianjin, Suzhou, Ningbo, Dalian, and Chongqing are developing rapidly in recent years. The position of manufacturing of Guangzhou had decline relatively in the domestic. The trend of re-industrialization of developed countries and digitalization of global manufacturing promotes Guangzhou to face lots of new challenges. The experience of world's manufacturing notice that excellent environment is the key to the industry rising. In this way, there is still huge room for improvement of Guangzhou, although the country has a comparative advantage in the past. The formation of "Lewisian turning-point" shows that the demographic dividend of China's economic development is not exist in the future. This also means that the industrial development model of plenty of lowcost labor and various resources inputs is unsustainable. Therefore, the Primer Li Keqiang claimed that economic development should rely on reform dividends. To promote a better and faster future, create a high-level and embeddedness manufacturing and maintain the sustainable development of the manufacturing, the first step of restructuring manufacturing in Guangzhou is consolidating adjustments of foundation. Of cause, the boldness and courage of reform and institutional innovation are essential. It is necessary to modify various types of hardware and software environment, striving to improve dominant position in the domestic. Specifically, in a hardway, we should increase the investment for transportation, communications, energy, environmental protection, education, culture, municipal, information technology and other infrastructure via introduction of private capital; In the soft aspects, It is a drastic measure to play high value on business environment, investment and financing environment, innovative environment, technology and talent. At the same time, accelerating the transformation of government functions, the reform of approval system, the transition to a service-oriented government are the key to create outstanding environment. In this way, can industrial restructuring achieve excellence result. ii. Homing on the Higher End of Value Chain, Promoting the Upgrading of Traditional Manufacturing Guangzhou as the Pioneering areas of Chinese modern industrialization was called "millennium city". it contain kinds of traditional manufacturing with long-term advantages such as textiles and garments, food and beverages, light chemical, leather goods, building materials. They have been played a pivotal role in the development of the Guangzhou Economic. However, due to its low value-added, labor-intensive features and the increasingly prominent and environmental pressures, the relative share of these industries are shrinking. Therefore, these traditional manufacturing should not give up but make them stronger promoting its industrial competitiveness and efficiency to improve. For the above purpose, it is wonderful to make full use of excellent market environment, kinds of factors of production, advantages of information, opened export trade platform and so on upgrading the traditional manufacturing of Guangzhou, based on promoting the policy of "double shift". To be specific, firstly, we should aim at the ends of Smiling Curve and extension of industry value chain to speed up the product technology innovation, cultivate independent brand of product, and strengthen marketing channel construction and network layout. Meanwhile, it is necessary to develop industrial products design, promote the use of advanced technology and especial the information technology to upgrading traditional manufacturing. Thereafter, simplifying the low-level processing and OEM and increasing the product technology content and added value are a proper way to enhance the competitiveness of the traditional manufacturing in Guangzhou. iii. Strengthen the independent innovation, promoting cluster scale expansion of advanced manufacturing "There are other hills where stones are good for working jade". The experience of the world's advanced manufacturing indicates that innovation and technology attaches great importance to industrial structure adjustment. The Mainly Manufacturing Structural component Curve shows that Guangzhou has stepped in the stage of electronic information, manufacturing equipment manufacturing industry, automobile, etc. as the leading industry. The industry has already become the most important pillar industry in Guangzhou formed a large scale and certain competitive advantage, and its relative share in the manufacturing industry is increasing. Obviously, it is a correct direction to adjust the manufacturing structure in Guangzhou. In order to further strengthen the embeddedness and market competitiveness of such industry, we should strive to strengthen the independent innovation, improve innovation resource allocation capabilities, construct the innovation carrier and platform, and improve the regionnal innovation system, promoting advanced manufacturing transform the "made in Guangzhou" into "innovative in Guangzhou". The advanced manufacturing of Guangzhou has been developing rapidly in recent years. The focus and paths of its development should be planed to further increase its competitive advantage. Moreover, we should promote the expansion of advanced manufacturing cluster start with two points extending the industrial chain and making enterprise bigger and stronger. At the same time, it is important to note that the scale expansion of advanced industry cluster should avoid to become low-level and homogeneity. It is a measure to cultivate lots of giant bibcock enterprise of market competitive advantage forming a batch of high, refined, pointed products and brands which build up a number of high-quality advanced industry cluster. iv. Increase the intensity of support, and accelerate the development of potential strategic emerging industry Under the circumstance of the country promotes the development of strategic emerging industries, in the future, Guangzhou should focus on the national strategy, and pool resources to develop biomedicine, new materials, energy conservation, environmental protection, rail transportation equipment, nuclear power equipment and Marine engineering equipment, etc. Although this type of industry is still in its initial stage at present and the industrial proportion is not high, but upgrading of the industry must be carried out in the long term. Therefore these industries are full of great potential and broad prospects, and are also the direction of the economic development. As far as we can see, these industries will be the pillar industry of national economy in the future. Guangzhou is in the transitional period, so it should vigorously promote the development of emerging industry in order to grab the commanding heights of science and technology. Based on the above consideration, it is necessary to constantly increase the support to potential strategic emerging industry, so that they can form its scale and competitive advantage as soon as possible. Government should pay attention to complete the system of the industrial policy, and give more discounts to this kind of industry in financial input, taxation, financing, etc. For the enterprises that have more leading ability, outstanding agglomeration features and those projects which have good economic benefit of technology innovation and technological transformation, the government should give more positive guidance and attract this kind of enterprises and projects located in Guangzhou. At the same time, the government can also guide the market demand through government procurement to support the promotion and application of emerging manufacturing product. In addition, the country can encourage to form a cross domain, crossindustry, cross-regional alliance of industry around the strategic emerging industry, promoting the strategic emerging industry of important regional resource configuration optimization and orderly development. ![of Manufacturing Structure in Guangzhou during 2001-2011 a) Data sources and Processing](image-2.png "") ![convenience, and you can see the changes of manufacturing production and the structure component.](image-3.png "") 2![Figure 2 : Mainly Manufacturing Structural component Curve](image-4.png "Figure 2 :") 1GOutput ValueYear20012002200320042005200620072008200920102011Electronic and Information Technology206.9297 306.0305 436.3698 607.3858667.3737 693.3572 679.3954 797.5649 1075.7434 1353.2504 1489.2553Electric Equipment and Special-purpose Machinery222.1659 246.9731 300.8052 316.0689397.6001 476.3435 567.5450 647.1127 624.0201 712.4017 737.8249Petroleum and Chemistry441.8745 488.7314 693.8331 888.0777921.5423 1012.9157 1242.5231 1428.5666 1370.4644 1627.2533 1941.2752Food and Beverage164.7842 172.0396 192.8396 214.3245233.2436 261.6947 287.1502 310.7688 421.2735 441.9613 506.8789Textile and Garments228.0730 250.6241 284.5794 268.3972309.8316 341.1307 342.2227 415.9149 455.3405 563.4212 625.7588Logging and Papermaking 105.6884 106.0397 109.8935 114.5358120.2004 130.0997 154.7403 200.3959 180.8756 223.0338 213.8944Medicine61.568159.835568.089967.029577.506888.828896.8492101.2387 116.2172 130.6335 137.1172Author ? ? ? : Guangdong University of Technology, Guangzhou, Guangdong, China. e-mail: 1450780585@qq.com 2Output ValueYear12345678910Electronic and Information Technology0.3200.4610.7530.6640.4550.1580.2160.4710.5680.601Electric Special-purpose Machinery Equipment and-0.047 -0.143 -0.265 -0.185 -0.158 -0.151 -0.138 -0.288 -0.324 -0.353Petroleum and Chemistry-0.0530.0420.1340.007 -0.059 -0.018 0.006 -0.174 -0.178 -0.085Food and Beverage-0.115 -0.290 -0.348 -0.388 -0.414 -0.464 -0.487 -0.376 -0.465 -0.429Textile and Garments-0.060 -0.233 -0.424 -0.421 -0.458 -0.556 -0.515 -0.537 -0.515 -0.500Logging and PapermakingMotor Vehicle0.0910.2620.3180.5270.7871.0320.9061.1081.1130.956-0.156 -0.394 -0.485 -0.537 -0.575 -0.572 -0.499 -0.618 -0.602 -0.650 Medicine -0.187 -0.334 -0.473 -0.469 -0.479 -0.528 -0.565 -0.561 -0.591 -0.603 b) Empirical outcome and analyzingWedraw the corresponding curve (as shown in figure1, 2), based on the data in table 1 and table2 for © 2014 Global Journals Inc.
