Tourism consumption can become the most active growth point to promote economic development，It can also become a driving force to promote the development of the trade circulation industry，In turn, it will drive the resource aggregation and integration of the commercial and trade circulation industry。Take tourism as the leader，Taking tourism consumption demand as the driving force，Formation of industrial agglomeration effect，And drive and extend business flow、Logistics、Funds、Message、Mobility gathering of talents and other resources，Thus promoting the resource aggregation of participating factors in the trade circulation industry。The tourism boom in the United States-Canada bet365 code has played a key role in regional economic development。

From a regional perspective，The bet365 code of North America consists of Ontario, Canada and eight states in the United States。Within the bet365 code，The Great Lakes urban agglomeration is a relatively important regional combination。Extending from the Midwestern United States to western Pennsylvania and upstate New York，and extending through southern Ontario to Quebec in southwestern Canada。The population of this region accounts for 50% of the Canadian population and more than 15% of the American population。

The development of water transport commerce in the 19th century，Promoted the rapid development of the Great Lakes urban agglomeration。The Illinois and Michigan Canal connects New Orleans to St. Louis、Chicago、The arc from Detroit to Buffalo to New York。During 1850-1970，At least 5 of the 10 largest cities in the United States are located on this arc。Chicago’s land market exploded during the construction of the canal in the 1830s。After the opening of the Ohio Canal and Erie Canal，Grain and oil、Meat product processing and trade cost reduction，Caused a large number of ranches to appear around the bet365 code。With the improvement of warehousing and logistics technology，The variety and throughput of trade continue to increase，By 1907，Cargo transported along the Detroit River has reached 67 million tons，More than three times the throughput of the ports of New York or London，The economic development of the bet365 code has achieved remarkable results。

During World War II，The bet365 code of North America relies on its unimpeded waterways、Highly developed transportation system、Advantages of financial center，And innovations in logistics and business organization，Become a leader in global manufacturing。1959，After the completion of the expansion of the St. Lawrence River and St. Lawrence River，The entire 3,700-kilometer line is navigable for 30,000-ton ships，80% of Atlantic ocean liners can reach the bet365 code directly。Expansion of this waterway，Greatly promoted the economic development of the bet365 code of North America，And gradually formed a diversified development pattern。For example，Rockefeller established pricing through Mobil、Logistics standard template for distribution and quality control。Ford’s automobile assembly lines and comprehensive production and sales capabilities have shaped Detroit into the world’s automotive center，And driven by tire demand，Transformed Akron, Ohio into a global leader in rubber production。During this period，Agricultural processing gradually formed in the bet365 code、Animal husbandry processing、Mining Mining and Transportation、Forestry mining, processing and transportation and the modern trade circulation system with the automobile manufacturing industry as the core，More than 200 million tons of cargo transported every year。

After 1980，With the rapid update of shipbuilding technology，The development trend of large-scale ships is gradually accelerating，The widespread use of 50,000-ton sea-going ships in the shipping market，The number of ocean-going ships entering the bet365 code has declined sharply。In addition，The rise of the air transport industry and the reduction of shipping costs，The competitiveness of manufacturing industries such as steel and automobiles in the region is gradually disappearing。The Detroit automobile industry is gradually unable to match the development of the Japanese automobile industry。Meanwhile，Due to the large-scale transfer of labor-intensive industries in the United States to overseas，Three major car companies in Toyota、Honda and Europe、Korean automobile companies are losing ground every step of the way，The decline of the manufacturing industry has affected the entire supply chain of the commercial circulation system。The decline of local economy has affected residents’ lives，The problem of population migration is prominent，Many middle-class and high-tech industries are experiencing serious job losses，The population of Detroit in 2010 was approximately 71.40,000 people，Compared to the peak of 1.85 million people in 1950，Sudden decrease in population。

What’s more important is，With agriculture in the bet365 code、The decline of traditional industries such as mining and forestry，The production capacity of old urban agglomerations is transferred with the transfer of global manufacturing centers。After the 2008 global financial crisis，The economy of the Great Lakes metropolitan area has fallen into a severe recession，The local government of Detroit declared bankruptcy in 2013。However，Although the financial crisis has had a serious impact on the Great Lakes urban agglomeration，It also provides opportunities for tourism to revitalize the local economy。The bet365 code is paying more and more attention to stimulating the growth of tourism consumption，Some metropolitan areas regard tourism and manufacturing as equally important，The development of tourism has become one of the main means to restore economic vitality。The natural and transportation foundation of the bet365 code creates objective conditions for tourism development to boost economic recovery。

First，Natural resources of bet365 code，Contains many sandy beaches、Island、Peninsula、Bay and estuary，Is the natural foundation for the development of tourism。For example，Michigan has the world’s largest、The most ecologically diverse freshwater lakeshore dunes；Indiana、Michigan and Ontario have about 30 large state or provincial parks。The winding shorelines of bet365 code、Numerous bays and frequent estuaries for cruise ships、Yacht、Sailboat、Water sports such as water skiing and boating provide a wide range of activities。Pollution reduction and fishing regulations，Also stimulates fishing、Camping、Hunting、Sightseeing、Skiing、The development of activities such as mountain biking (summer) or snowmobiling (winter) and related sporting goods manufacturing。Not only that，The catering industry accompanying tourism、Accommodation Industry、The ship leasing and buying and selling industry has also developed accordingly。

Second，Developed highways in the bet365 code、The railway and aviation systems have made important contributions to promoting the development of tourism。Based on the current situation that Americans prefer to go to Canada for vacation，Ontario, Canada, on the basis of ensuring efficient and modern transportation infrastructure，Built 14 land border crossings and 16,500 kilometers of highways，Greatly facilitates American tourists and international tourists entering Ontario，Convenience for travelers who own private cars and prefer to travel by bus and train。Not only that，The United States and Canada have also built large entertainment venues in their respective border cities，Attracting millions of tourists from both countries and other international countries to visit。In addition，The busy international airports in the Great Lakes metropolitan area also provide strong support for the bet365 code to attract international tourists from outside North America。For example，Toronto’s Pearson International Airport is the second busiest international airport in North America。In addition to direct flights to 54 cities in the United States, this airport’s international flights，You can also fly directly to 99 other international cities，Providing more than 500,000 flights to 47 million passengers every year。

After nearly ten years of development，Tourism has become an important support for the economy of the bet365 code of North America，Regional economic development has achieved positive results driven by tourism。What’s more important，Tourism development has made an important contribution to employment in the bet365 code。Data display，Tourism has become the ninth largest employer industry in the bet365 code，Employs approximately 2.7 million workers，Provides 6% of the jobs in the region，4 above the North American average.5%，its employees are widely distributed in accommodation、Transportation、Retail、Entertainment and catering departments。It can be said，Tourism development plays a key role in the economic transformation of the bet365 code，And will remain an important force in the economic development of the bet365 code in the future。
