A Comparative Analysis of Effective Free Trade Zone Policies in Ghana : A Model from Shanghai Free Trade Zone

The importance of export promotion contribution to the growth of a country’s economy cannot be underrated. It is well-established that, encouraging volumes of exports and/or value of exports results in the increase in the export of a country leading to an increase in earnings of foreign exchange and further results in economic boost of a country. A comparative analysis of effective Free Trade Zone Policies in Ghana using China (Shanghai) Pilot Free Trade Zone (“SHFTZ”) as a model has been done. Desktop research was used to analyze the data. It was found that there has been year on year increase in the number of companies registering with the Ghana free zones. On the average, there have been about 15% contribution to the gross export of Ghana. The China (Shanghai) Pilot Free Trade Zone (“SHFTZ”) contributed 5.68%, 13.2%, 15.2% and 22.9% from the first quarter after the inception of the FTZ, at the end of 2014, 2015 and 2016 respectively to the GDP of Shanghai.


Introduction
One strategy to achieve a good economic performance is to increase export.Free Zones has been identified and been used vigorously as an export support strategy [1].The free trade zone historically, dates back to the ancient Phoenicians era, when safe passage was the principal guarantee offered foreign traders coming to Tyre and Carthage [2], Free Trade Zone in the beginning were tools for the ag- gressive commercial power [3].The first concept of international free trade zone was created by the Phoenicians [4].This was followed by the Greek City-States and the Romans, the Romans established it into launching pads that were used as a tool for economic and political supremacy.For centuries, secure trade routes like Singapore, Gibraltar and Hamburg have been operating citywide free zones and entrepots that have free storage and exchange guarantee [5].As early as 1704 and 1819, Gibraltar and Singapore respectively had well established free trade zones [3].In 1960s, the "United Nations' Economic and Social Council" adopted a resolution at the 1506 th plenary meeting on August 41,967, suggesting that improving customs, ports and free zones infrastructure in developing countries is one of the primary ways of encouraging export expansion [5] [6].In Shannon, Ireland in 1959 the first modern free zones of industrial scale were established [4].
United Nations Development Program defines Free Zones as the various types of geographically delimitated area that exist within a country, functioning with a distinct administrative, fiscal and regulatory systems, different from the remaining part of the country [7].Economic experiments are carried out in these zones with infrastructure, regulatory, and fiscal policies, which differ from policies implemented in the remaining domestic economy, with the sole objective of employment creation boost in export and attraction of foreign direct investment [8].Zones with these characteristics are given diverse names by different countries.These names are; Export Free Zones, Maquiladora, Industrial Free Zone, Duty Free Export Processing Zone, Export Processing Zone, Free Export Zone, Free Zone, Investment Promotion Zone, Foreign Trade Zone, Development Zones, Economic and Technological Development Zones (ETDZs), Hi-tech Development Zones (HIDZs) and Special Economic Zones (SEZs) [9] [10].The international labour organization estimates about 3500 FZs exist currently in the world in about 130 countries and territories.The number of countries using FZs increased to 130 in 2006 from 116 in 2002 and 25 in 1975 [11].
Policy-makers across the world especially developing economies are carrying out various forms of Free Zones (FZs) programs with the intension to catalyze economic growth.According to literature, the main implementation objective(s) of free zones is to serve at least one of the following four policy objectives; 1) foreign direct investment attraction to the country, export promotion and ultimately industrialization; 2) to serve as a "pressure valve" for large scale unemployment alleviation 3) serve as a pillar for a broader economic reform strategy and 4) serve as laboratories for new policies and approaches experimentation [3] [4] [12] [13] [14].Free zones can be used as effective industrialization promotion mechanism and if executed correctly in the right context has the tendency to push the entire country on faster economic developmental trajectory [15] [16] [17] [18].[23].In the opinion of some environmentalists "free trade can destroy the environment".Thus, a section of the large and powerful environmentalist lobbyist has joined the growing alliance of interests seeking to scuttle what is left of international free trade [24].Shah and Rivera (2008) on the other hand revealed that in the case of Trinidad and Tobago's EPZs the situation is different and that facilities operating in the zones have a higher probability of better cooperate environmental performance when compared with those outside the zone [25].Several countries have had success with their SEZ, contributing immensely to their economic development whereas others have had utterly unsuccessful implementation of their SEZ.For instance, the government of the Philippines made substantial infrastructural investment for their zone in Bataan.This involved the upgrade of the port, erecting an elegant office building and the construction of a new energy supply dam.However, the much attraction needed for business to be established in the zone failed, rendering the project a very expensive failure to the Philippine government [28].[35].One purpose of setting up the free trade zone is to use it as a policy testing ground and spread it consecutively to other parts of the country when those policies and practices have fully-fledged [35].

Evolution of the Ghana Free Zones Policy
Export promotion as a tool for economic growth is highly emphasized.It is acknowledged in theory that promoting volume and/or value of exports brings an increase in exports, increases foreign exchange and further improves a country's economy.Success in manufactured exports has been measured to be synonymous with rapid economic development.In the last thirty years' success in manufactured exports has been nearly synonymous with rapid economic development [36].Export promotion in Ghana is seen as an important policy instrument for the country in achieving sustainable economic growth.In order to promote competiveness in Ghana exports, several policy instruments have been adopted.

These include the Economic Recovery Program (ERP) initiated in 1983. The
Free Zones policy instruments have become a very popular instrument after its introduction.Free zones have become important part of policy instruments in developing economies in their quest to attract foreign investment, promote non-traditional exports and to increase exports in total [37].as a gateway to the West African sub-region.The Free zones under the Gateway project was established to pull in a large number of investors who were export-oriented in order to facilitate export-led growth and trade in general.Ghana in a bid to kick-start the growth of the economy, adopted the free zones concepts over a decade ago.This was meant to attract investment and capital and to encourage competitive enterprises focus mainly to produce for export [37].

Objectives of the China (Shanghai) Pilot Free Trade Zone
The State Council issued the "China (Shanghai) Pilot Free Trade Zone Overall Plan" ("SHFTZ Plan") within three weeks after the NPC promulgated the document that gave authority to the State Council over the SHFTZ.The principal objectives of China (Shanghai) Pilot Free Trade Zone (SHFTZ) are: 1) To accelerate governmental change in accordance with a changing economic environment [29].
2) To research new methods of administrative regulation [29].
3) To promote trade and investment [29].4) To serve as an experiment for national regulatory reform [29].
The SHFTZ Plan provides guidelines for the initial three years of the SHFTZ, it focuses on reforms concerning foreign investment, trade, financial services, merchandise classification, and currency exchange [29].With the above main objectives, six areas of focus for the free trade zone were emphasized to bring forth the multi-layered mission of the SPFTZ.These are: financial services; shipping and logistics; commercial trade; professional services such as law and engineering; culture and entertainment; and social services including education and healthcare [35].

Objectives of the Ghana Free Zones
The Ghana free Zones was established to achieve the below objectives: • Attraction of Foreign Direct Investments [38]; • Creation of employment opportunities [38]; • Increasing foreign exchange earnings [38]; • Provision of business opportunities for foreign and local investors to undertake joint-venture [38]; • Enhancement of technical and managerial skills/expertise of Ghanaians; Promotion of the transfer of Technology and Diversification of Exports [38].

Organizational Structure of SHFTZ-Economic Zones and the Decentralized Governance Model
China's path of development has closely resembled those of Taiwan, Singapore and South Korea in the sense that economic development has been accompanied and enhanced by the central authority being delegated, and promoting sufficient autonomy for domestic social groups and markets [39].There has been a recognizable increase in the power of the local government to regulate the areas under their jurisdiction as a result of decentralization of economic power to lower administrative levels.While carrying on this process, market mechanisms have been transplanted into the economic arena [35].The SHFTZ is made up of a complex structure of decentralized governance model of governmental organizations (Figure 1) that are categorized into two administrations for industry and commerce ("AICs") and a variety of local offices [29].

Governance of the Ghana Free Zone Authority
The organizational structure of the Ghana Free Zones Authority is depicted in   This is still employed outside the SHFTZ SFTZ2.With SHFTZ, foreign investors are able to invest freely in sectors not on the "Negative List" without any constraints or any joint venture requirements.Foreign enterprises register their projects, without the need to apply for approval.Thus, investments by foreign entities domestic entities go through the same procedures [42].

Faster, Simpler Business Registration
The business registration approval duration has been reduced to less than a week, while import and export license takes two weeks.The steps needed for the business registration (Figure 3) has also been made easy.The authorities are providing a One-stop filing and registration procedure instead of an approval process.The company is able to complete other necessary procedures on its own [43].Minimum capital requirements for companies in particular industries, for instance financial companies that provide loan services have been relaxed.In the SHFTZ annual inspection system has been substituted with annual reporting [42].Furthermore, having a virtual office in the SHFTZ is possible but this is not permitted in all parts of China [44].

Trade
The SHFTZ opens up the business front line (the boundary between the Shanghai SHFTZ and overseas) and effective control in the second business line (i.e.
the boundary between the SHFTZ and the rest of mainland China), and then free flow within the SHFTZ itself: The sales of the products into the non-FTZ Figure 3. Processes for establishing a business in SHFTZ (Adopted from: Grmanova. CzehTrade) [42].
from the SHFTZ is regarded as domestic import implying that applicable processes have to follow, Frontier Opening: This implies products will be given

Ghana Export Processing Zone Incentives
Enterprises established in these zone enjoy these incentives: 100% exemption from payment of direct and indirect duties and levies on all imports for production and exports from free zones, 100% exemption from payment of income tax on profits for 10 years and shall not exceed 8 percent thereafter, total exemption from payment of withholding taxes from dividends arising out of free zone investments, total exemption from payment of withholding taxes from dividends arising out of free zone investments, relief from double taxation for foreign in- acres and affords investors a suitable environment for production such as the convergence of all frontline export promotion institutions into a one-stop-shop.
There are good road networks that link Tema EPZ to the airport and seaport [37].

Ashanti Export Processing Zone.
The Ashanti EPZ with a land area of 1099 acres is located in the Ashanti Region in Ghana and close to the inland port of Boankra.This enclave when developed is envisaged to be an ICT Park.It is to provide the necessary telecommunications enabling infrastructure for investors.It would have facilities including, warehousing, agro processing and light industrial/electronic sub-enclaves with a complementary residential estate for enclave employees [37].

Sekondi Export Processing Zone
This zone has been earmarked for oil refinery and related activities.It has a land area of 2200 acres.A direct rail link to Ghana's second seaport is ideal to harness the proximity of this EPZ for heavy industrial activities [37].

Shama Export Processing Zone
A third zone, the Shama Export Processing Zone, has been designated as a multi-purpose enclave and has a land area of 3000 acres.With this enclave interested developers are welcomed to develop the enclave [37].

Shanghai Pilot Free Trade Zone Performance
Progress in the following areas has been in place since the commencement of the SPFTZ in 2013.First of all, there has been a quick increase in newly registered enterprises.There were 12,547 new registered enterprises in the SPFTZ by 26 September 2014, consisting of 10,788 domestic investment enterprises and 1759 foreign investment enterprises.As seen in Figure 5, there was a steady increase, from 11.6% to 24.9% of the proportion of foreign investment enterprises [26].
Secondly, financial innovation in SHFTZ has made progress.As at the period of discussion, there were 484 free trade accounts operated by enterprises, and the RMB balance of these accounts was about 90 million.As can be seen in Figure 6 in the first quarter after the inception of the SHFTZ, not much growth or contribution to the Shanghai economy was observed, only 5.68%.SHFTZ was estimated to have contributed about 13.2% of Shanghai GDP, increasing to 15.2% and 22.9% in 2015 and 2016 respectively.These figures give a clear indication of the contribution of the SHFTZ to the acceleration of the economy of the area as in accordance with the maturity expectations [47].
Many financial institutions have business in the SHFTZ, including 23 foreign banks, 14 Chinese banks, three security companies and 11 insurance companies.
Twenty-eight (28) enterprises had built so called "RMB money ponds" in the SHFTZ, having a balance of 16.9 billion.The RMB cross-border settlement in the SHFTZ is 111.5 billion.Seventy (70) of the enterprises are involved with RMB finance from abroad and are running on a balance of 16.06 billion [26].
Registered enterprises within the SHFTZ have continuously increased to a  total of 25,304 of which sixty-seven percent (67%) of them were registered after the SHFTZ was set up.Meanwhile, each enterprise's registered capital has increased from 43.71 million to 63.36 million [48].As informed by the local official of the SHFTZ, in 2015, the number of registered foreign-invested enterprises within the SHFTZ increased by one and a half times that in 2014.This as they noted, covers about half the total number in the whole city of Shanghai.Foreign-invested enterprises in the SHFTZ have increased from 5% (from the beginning) to 20% for the period under discussion.The average registered capital of foreign-invested enterprises is twice that of domestic-invested enterprises [48].
Table 1 shows the changes on income, tax, profits, and number of employees before and after the SHFTZ was set up in 2013.Apart from few figures like Investment and exports due to the fast increase rate of imports and exports within SHFTZ.What is significant here is the volume of imports and exports via the SHFTZ, particularly with regards to the rapid increase after the SHFTZ was set up.This proves the SHFTZ concept's attraction to investors [48].

Registration of Companies
Since the inception of the free zones program, a number of companies have been licensed under the scheme in order to benefit from the incentives that render them competitive and also give them the opportunity to reach a large international market.The Ghana Free Zones Board has progressively registered new companies each year.Total number of registered free zone companies as at 2014 was 352; the yearly distribution from 1996/97 to 2014 is shown in the graph (Figure 7).

Employment Generation
Total employment generated under the Free Zone Program as at the end of 2014 was 30,271 the yearly distribution is shown in Figure 8.

Production Value
Annual production value of Free Zones Companies in 2014 was US$2200.18M.
The yearly figures from 1996/97 to 2014 are shown in the graph (Figure 9).

Total Expor
Annual total export value of licensed Free Zone Enterprises from 1998 to 2014 amounted to US$26,563.33.The breakdown is shown in Figure 10.program to increase investment from foreign investors.The benefits of foreign investment are relatively obvious-more capital, increased access to foreign markets, economic development, and availability of foreign products to domestic consumers notwithstanding, there are concerns to foreign investment.Firstly, there is a probability of it influencing domestic politics.China has historically resisted foreign influence strongly, so this SHFTZ has been a significant policy consideration.Secondly, there was a reduction in fund received by the central government due to the incentives introduced by the program.Shanghai, the financial centre of China was chosen strategically as the testing grounds for the economic reforms.This was to enable the program to balance the negative and positive sides of foreign investment promotion, to limit the risk that SHFTZ can bring while maximizing the potential gains.Shanghai hold offices for a number of foreign companies and is also noted for hosting conferences and events on trade promotion.So initially consolidation of the existing four Free Trade Zones was a good way of making use of existing infrastructure and also taking advantage of proximity to foreign companies.With a GDP contribution of 5.68%, 13.2%, 15.2% and 22.9% from the first quarter after the inception of the FTZ, at the end of 2014, 2015 and 2016 respectively, to the Shanghai economy it can be said finally that the SHFTZ idea has yielded its intended goals significantly.

Variation in the Zone Performance: The Ghana Free Zones
There has been year on year increase in the number of companies registering for the free zone initiative.Even though the rate of export has increased over the years under discussion, it has not been that prominent.Taking the exports from the export processing zone as a proportion of the gross exports of Ghana, one can see an average of 15% to the gross exports of the country as can be seen in  can to a greater extent tow the China line of decentralized zone creation and governance.While business registration approval duration for SHFTZ has been reduced to less than a week, while import and export license takes 2 weeks, the approval duration for the Ghana free Zones take about 28 days.

Conclusion
A comparative analysis of effective Free Trade Zone Policies in Ghana using China (Shanghai) Pilot Free Trade Zone ("SHFTZ") as a model has been done.
The pilot project of the Shanghai free trade zone was successful in its implementation, leading to increase in zone demographic area the elimination of some trade regulations in China.The decentralized nature of the governance structure of the Shanghai free trade zone and the quality of infrastructure have been major success factors.The Ghana export processing zone on the other hand has been performing fairly well, but can do better.There has been a gradual increase in the firms registering and carrying out business in the zone.The Export processing zone was initiated with an important aim of boosting the gross national export but has not been contributing much since its inception.

Recommendation
• There should be the necessary regulatory amendment to streamline company registration with a one-stop-shop approach.• The processes of relevant institutions like the Customs, Excise & Preventive Service, the Ghana revenue Authority, the registrar General department etc. need the necessary regulatory amendment to streamline their processes, red tape and bureaucracy to aid the agencies fast track commercial activities for these companies.
• There should be massive development of railways and other relevant infra-

After 15 years
of economic reforms prior to the inception of the Free Zones program in Ghana, Ghana's business environment was said to be amongst the best in Africa for private sector development.This was after a benchmark study was commissioned by the Government of Ghana for the Gateway project to compare investment climate to those of Mauritius and Dubai (considered best practices); and Togo and Kenya (potential competitors).The study confirmed that Ghana compares favorably to Togo and Kenya and had advantages that make it attractive to Mauritius and Dubai.However, foreign investors in Asia, Europe and other parts of the world were largely not aware of the Ghana's business potential both as a platform for production for the world markets and also D.

2. Evolution of Free Trade Zone 2.1. Evolution of the China (Shanghai) Pilot Free Trade Zone Policy
Despite its enormous trade volumes, the national government is encouraged to test new methods to promote international trade and foreign investments due to the slowing domestic economy.The NPC onAugust 30, 2013, promulgated the "Decision of the Standing Committee of the National People's Congress sanctioning the State Council to Provisionally Adjust the Applicable Administrative Approval Items Set in Laws in China (Shanghai) Pilot Free Trade Zone".The four aforementioned SEZs were stated in this legislation to be merged into one single FTZ and authority was given to the State Council to create administrative guidelines to set up and regulate the SHFTZ for three years.Pursuant to this document, the SHFTZ was established on October 1, 2013 [29].The most advanced Shanghai Pilot Free Trade Zone (SPFTZ) in Shanghai was reinvigorated by the government of China in September 2013 and is seen as another key [29]service that it offers are the same as that of the SEZs in the SHFTZs and the success of the Pudong Airport Free Trade Zone is attributed to its superior air and land transport systems.Pudong Free Trade Zone went into strategic development alliance with the other three SEZs called the ("Three Ports, Three D.
